Hi,
In Facebook there are various applications which makes a collage of all your friends. The application may be showing your top followers, or friends who are in your same organization and so on. In this post I have created a PHP script to do exactly the same. But for demo I have used a static array of users to create the collage image, which of course you can convert to a dynamic array fetching data from the database.
First lets see the output:
Everytime you refresh the sequence of users will get shuffled and the angle of rotation of the images are also randomly selected between -10 to +10 degrees. Few prerequisites before using the code is to copy a font file(.ttf) and paste it in the directory of the code. Rename the ttf file to "cfont.ttf". Secondly and most important is to enable you GD library if it is not enabled.
The code to get the above is:
<?php
$im=imagecreatetruecolor(300,300);
$white=imagecolorallocate($im,255,255,255);
$black = imagecolorallocate($im, 100, 100, 100);
imagefilledrectangle($im,0,0,800,500,$black);
$font = 'cfont.ttf';
$users=array();
$users[0]['image']="statham.jpg";$users[0]['name']="Jason Statham";
$users[1]['image']="antonio.jpg";$users[1]['name']="Antonio Benderas";
$users[2]['image']="will_smith.jpg";$users[2]['name']="Will Smith";
shuffle($users);
$marge_left=20;$marge_top=20;$i=0;
foreach($users as $key){
$i++;
$img_element=imagecreatefromjpeg($key['image']);
$angle=rand(-10,10);
$img_element = imagerotate($img_element, $angle
, $black);
$text=$key['name'];
imagettftext($img_element, 10,0, 10, 20,$white, $font, $text);
imagecopy($im, $img_element, $marge_left, $marge_top, 0, 0, imagesx($img_element), imagesy($img_element));
$marge_left+=120;
if($i%2==0){
$marge_left=20;
$marge_top=$marge_top + 120;
}
}
header("content-type: image/jpeg");imagejpeg($im,null,100);
