Code added to this post will calculate date difference in days, months, years format. So using this code you can calculate age by sending birth date as parameter. Or you can calculate difference between today’s date and any date in past.


function get_Age_difference($start_date,$end_date){
	list($start_year,$start_month,$start_date) = split('-', $start_date);
	list($current_year,$current_month,$current_date) = split('-', $end_date);
     $result = '';

    /** days of each month **/

    for($x=1 ; $x<=12 ; $x++){

        $dim[$x] = date('t',mktime(0,0,0,$x,1,date('Y')));

    }

    /** calculate differences **/

    $m = $current_month - $start_month;
    $d = $current_date - $start_date;
    $y = $current_year - $start_year;

    /** if the start day is ahead of the end day **/

    if($d < 0) {

        $today_day = $current_date + $dim[$current_month];
        $today_month = $current_month - 1;
        $d = $today_day - $start_date;
        $m = $today_month - $start_month;
        if(($today_month - $start_month) < 0) {

            $today_month += 12;
            $today_year = $current_year - 1;
            $m = $today_month - $start_month;
            $y = $today_year - $start_year;

        }

    }

    /** if start month is ahead of the end month **/

        if($m < 0) {

        $today_month = $current_month + 12;
        $today_year = $current_year - 1;
        $m = $today_month - $start_month;
        $y = $today_year - $start_year;

		}

    /** Calculate dates **/

    if($y < 0) {

        die("Start Date Entered is a Future date than End Date.");

    } else {

        switch($y) {

            case 0 : $result .= ''; break;
            case 1 : $result .= $y.($m == 0 && $d == 0 ? ' year old' : ' year'); break;
            default : $result .= $y.($m == 0 && $d == 0 ? ' years old' : ' years');

        }

        switch($m) {

            case 0: $result .= ''; break;
            case 1: $result .= ($y == 0 && $d == 0 ? $m.' month old' : ($y == 0 && $d != 0 ? $m.' month' : ($y != 0 && $d == 0 ? ' and '.$m.' month old' : ', '.$m.' month'))); break;
            default: $result .= ($y == 0 && $d == 0 ? $m.' months old' : ($y == 0 && $d != 0 ? $m.' months' : ($y != 0 && $d == 0 ? ' and '.$m.' months old' : ', '.$m.' months'))); break;

        }

        switch($d) {

            case 0: $result .= ($m == 0 && $y == 0 ? 'Today' : ''); break;
            case 1: $result .= ($m == 0 && $y == 0 ? $d.' day old' : ($y != 0 || $m != 0 ? ' and '.$d.' day old' : '')); break;
            default: $result .= ($m == 0 && $y == 0 ? $d.' days old' : ($y != 0 || $m != 0 ? ' and '.$d.' days old' : ''));

        }

    }

    return $result;

}

/* Call this function as */
$date_difference= get_Age_difference("2004-10-10",date("Y-m-d")); /* get_Age_difference(Birthdate,Todays_date) */
echo $date_difference;

Above code will output difference in format like
5 years, 10 months and 13 days old

PHP Add One Month, one day or one Year to todays date

snilesh — Sat, 26 Jun 2010 08:16:58 +0000

This example shows you how to add one day, one month or one year to todays date using PHP Date Functions.
for more information refer PHP.net

";

//Add one day to today
$dateOneDayAdded = strtotime(date("Y-m-d", strtotime($todayDate)) . "+1 day");

echo "After adding one Day: ".date('l dS \o\f F Y', $dateOneDayAdded)."
";

";
?>

Create Image using PHP

snilesh — Thu, 04 Mar 2010 10:47:10 +0000

PHP have mosts of functions available to create a image on the fly. You can use these functions to create a captcha image or a add banner on the fly.

Create Image

Create image using the PHP function createimage(), function will create image with the dimensions of the image, namely its width and height in that order

Apply Colors

Next thing is to apply colors using the imagecolorallocate() function.
Colours are allocated using the imagecolorallocate() function. This function will automatically fill the background of the image with the colours you specified, and return an identifier for that particular colour. Subsequent calls to imagecolorallocate() will create a colour identifier for your colour.
imagecolorallocate() returns FALSE if the function fails for any reason.

Write Text On Image

We can write text on images using the function imagestring().
imagestring ( resource $image , int $font , int $x , int $y , string $string , int $color );
1] $image is image source
2] Font Can be 1, 2, 3, 4, 5 for built-in fonts in latin2 encoding
3] x-coordinate of the upper left corner.
4] y-coordinate of the upper left corner.
5] The string to be written.
6] A color identifier created with imagecolorallocate().

Display Image

Image is created using imagejpeg()
In this example i passed header( “Content-type: image/jpeg” ) as i want to create a jpg image.
Other functions are
1]imagepng()
2]imagegif()

Free Resources

Free individual resources which are created using the imagecolordeallocate() function and the image resource using the imagedestroy() function.

Following code will retrieve all file names from a specified folder.

";
    $fileCount++;
  }

  echo sprintf("All Files in %s

%sTotal Files: %s",$filePath,$string,$fileCount);
}
?>

Get Image width height type using PHP

snilesh — Sat, 02 Jan 2010 11:52:23 +0000

This is excellent php function which can be used to get Width,Height,Type of a Image using PHP. for more information read PHP.net

echo "
";
echo "Height " .$height;
echo "
";
echo "Type " .$type;

Jquery PHP Multiple File Upload

snilesh — Tue, 18 Aug 2009 06:46:02 +0000

Here in this post i created multiple file upload using latest version of jQuery and Ajax upload library by Andrew Valums. Just download both libraries and include them in your files.

Then first we will create a upload button and when user click on this button user can add files. we are not using classic File input box for the file upload

   1. 
   2. Upload File

   3. 
   4.

Here we created the Upload button and for the status message which is used to display the status of the file upload

Applying Style

#upload_button{
	margin:30px 200px; padding:8px 5px 8px 5px;
	font-weight:normal; font-size:1em;
	font-family:Georgia,Arial, Helvetica, sans-serif;
	text-align:center;
	background:#000000;
	color:#ffffff;
	border:2px solid #DADADA;
	width:150px;
	cursor:pointer !important;
	-moz-border-radius:5px; -webkit-border-radius:5px;
}

#status_message{
	font-family:Arial; padding:5px;
	color:#b00000;
	font-size:12px;
	font-weight:bold;
}
ul#files_list{ list-style:none; padding:0; margin:0; }
ul#files_list li{ padding:10px; margin-bottom:2px; width:200px; float:left; margin-right:10px; text-align:center;color:#ffffff;}
ul#files_list li img{ max-width:180px; max-height:150px; }
.success{ background:#000000; border:1px solid #cccccc; }
.error{ background:#f0c6c3; border:1px solid #cc6622; }

PHP code to upload files

Files are uploaded to the “uploads” folder. for that create ‘upload-file.php’ files with the above code.

Javascript Code

Now the Jquery and Javascript code to add the ajax features using the AJAX Upload library.

$(function(){
		var btnUpload=$('#upload_button');
		var status=$('#status_message');
		new AjaxUpload(btnUpload, {
			action: 'upload-file.php',
			name: 'uploadfile',
			onSubmit: function(file, ext){
				 if (! (ext && /^(jpg|png|jpeg|gif)$/.test(ext))){
                    // extension is not allowed
					status.text('Only JPG, PNG or GIF files are allowed');
					return false;
				}
				status.text('Uploading...');
			},
			onComplete: function(file, response){
				//On completion clear the status
				status.text('');
				//Add uploaded file to list
				if(response==="success"){
					$('
').appendTo('#files_list').html('
'+file).addClass('success');
				} else{
					$('').appendTo('#files_list').text(file).addClass('error');
				}
			}
		});

	});

Code Explanation

To use the AJAX Upload library we need to initialize the AjaxUpload object and provide it with parameters. The first parameter is the id of the button element on which the user will click and second is the server side script that’ll handle file upload. The second parameter can accept an array of various options to give you more control over the process.

For more details of the of options for file upload you can check the Ajax Upload Library.

Note: The file upload using AJAX is not true ajax as it uses hidden iframe to upload the form data but his whole process is transparent by using the AJAX Upload library and gives a feel of AJAXified file upload.

Dynamic Font Replacement

snilesh — Thu, 30 Jul 2009 17:05:05 +0000

For every website design Typography plays a very important role.
And in current website trends there are many fonts used for better user experience but on most of cases they are not system fonts so cant be displayed on any cases.
For this fonts problem there is a solution i.e. Image Replacement which has always been a good solution.

Here I put together a clean list of popular Dynamic Image Replacement solutions that will help you solve various font related issues.

1] sIFR 2.0

sIFR is meant to replace short passages of plain browser text with text rendered in your typeface of choice, regardless of whether or not your users have that font installed on their systems. It accomplishes this by using a combination of javascript, CSS, and Flash.

2] SIFR 3

sIFR lets you use your favorite font on your websites by cleverly working with Flash, JavaScript and CSS.

3] SIIR

The SIIR program serves to basically change dynamic text on your website into pretty generated images with any font of your liking.

4] cufón

Cufón aims to become a worthy alternative to sIFR, which despite its merits still remains painfully tricky to set up and use. Cufón consists of two individual parts – a font generator, which converts fonts to a proprietary format and a rendering engine written in JavaScript.

5] P+C DTR

P+C DTR allows you to take a vanilla standards-based (X)HTML web page and dynamically create images to replace and enhance page headings using only PHP + CSS.

6] FLIR

FLIR dynamically generates image representations of text on your web page in fonts that otherwise might not be visible to your visitors. The generated image will be automatically inserted into your web page via Javascript and visible to all modern browsers.

7] DTR

A pretty old JavaScript and PHP technique by Stewart on A List Apart.

8] Typeface.js

Instead of creating images or using flash just to show your site’s graphic text in the font you want, you can use typeface.js and write in plain HTML and CSS, just as if your visitors had the font installed locally.

9] IFR

By using a dynamic Flash movie, some slick JavaScript and well-structured mark-up the same consistent branding can be achieved while greatly reducing production time and preserving the cleanliness of the mark-up.

10] PHP+CSS DTR

PHP+CSS Dynamic Text Replacement is a JavaScript-free version of the Dynamic Text Replacement method originally created by Stewart Rosenberger. This is the P+C DTR version with word-wrapping and the ability to use inner tags.

11] CSS Image Replacement [static]

Just thought we could include this nice article by Chris Coyier explaining 9 different CSS Image Replacement Techniques. These techniques are the best if you just have very few elements to be replaced.

12] swfir

Using the dark arts of JavaScript and Flash, swfIR gives you the ability to apply an assortment of visual effects to any or all images on your website. This is again not for fonts but is another dynamic image enhancing solution.
