The most straightforward way is to use PHP's imageXXX() routines, such as imagecreatefromjpeg() etc. For more powerful scripted image editing, consider ImageMagick, or some other scriptable image processor.

ImageMagick offers best quality and lot of other features. Use adaptiveSharpenImage function:

<?php
try
{
    $image = new Imagick('image.png');
    $image->adaptiveSharpenImage(2,1);
}
catch(ImagickException $e)
{
    echo 'Error: ' , $e->getMessage();
    die();
}

header('Content-type: image/png');
echo $image;
?>

Here's an unsharp mask for PHP. (Unsharp mask is one of the most common types of sharpening used.)

Here's another option (using GD).
