Best PHP Image Crop Class

Question

I\'m designing a website and I need to:

• Upload the image
• Validate that it\'s an image (and not, oh I don\'t know.... a virus :) )
• Resize the Imag

Answer 1

My personal favorite Image Manipulation Library is WideImage. It makes is ridiculously easy to do that kind of task.

WideImage::load('pic.png')
->crop('center', 'center', 90, 50)->saveToFile('cropped/pic.jpg');

As for validating if it is actually an image or not, use finfo or PEAR::Mime_type. I personally prefer PEAR::Mime_Type. It uses finfo but it's just simpler to use.

Using finfo:

$finfo = finfo_open(FILEINFO_MIME_TYPE);
$mimetype = finfo_file($finfo, $filename);

$isImage = (preg_match('#^image/#', $mimetype) === 1);

Using PEAR::Mime_Type:

$mimetype = MIME_Type::autoDetect($filename);

$isImage = MIME_Type::wildcardMatch('image/*', $mimetype);
