PHP bulk zoom image code [ini parameter control]

First, use an ini file to set the size of the image to be scaled. If the image is wide or high 0, it will enlarge or shrink. If both are 0, it will still be the same size.

Note: the ini file is interpreted as an annotation file using PHP and has no output, which is intentional for security reasons. But; Is the comment to the ini file.

An example of the ini file I set is as follows:

 
<?php 
 
?> 

The following is the PHP code written to scale the image. The variable classes is an array, and you can select the Settings specified in any number of ini files:

 
<?php 
$oimg = "test.jpg";//Original image name 
$classes = array('Translation','AutoHeight','AutoWidth','Stretch');//Give classes for the new creating images' size which are defined in the specified ini file 
$suffix = 'jpg';//The new image's suffix 
$inifile = 'image.ini.php'; 

$size = getimagesize($oimg); 
$x = $size[0]/$size[1]; 
$name = explode('.',$oimg); 

if(!file_exists($inifile)) die('Ini file does not exist!'); 
$cn = parse_ini_file($inifile,true);//Parse the class style image size from ini file 
foreach($classes as $class){ 
foreach($cn as $k=>$v){ 
if($k==$class){ 
if($v['width'] && $v['height']){ 
$thumbWidth = $v['width']; 
$thumbHeight = $v['height']; 
}elseif($v['width']){ 
$thumbWidth = $v['width']; 
$thumbHeight = round($thumbWidth/$x); 
}elseif($v['height']){ 
$thumbHeight = $v['height']; 
$thumbWidth = round($thumbHeight*$x); 
}else{ 
$thumbWidth = $size[0]; 
$thumbHeight = $size[1]; 
} 
break; 
} 
} 
if(!isset($thumbHeight) && !isset($thumbWidth)) die('Ini file Settings error!'); 

$nimg = $name[0].'_'.$class.'.'.$suffix;//New image file name 
$source = imagecreatefromjpeg($oimg); 
$thumb = imagecreatetruecolor($thumbWidth, $thumbHeight); 
imagecopyresampled($thumb,$source,0,0,0,0,$thumbWidth,$thumbHeight,$size[0],$size[1]); 

if($suffix=='jpg') $method = 'imagejpeg'; 
else $method='image'.$suffix; 
$method($thumb, $nimg); 
imagedestroy($thumb);//Release the image source 
imagedestroy($source); 
} 
?>
