How to resize image in PHP?
Images can be resized using ImageMagick or GD functions. If GD’s functions are used, the size of the image file is also reduced when raw digital camera images are sampled. We will see how GD can be used to resize an image in the below code.
function image_resize($file_name, $width, $height, $crop=FALSE) { list($wid, $ht) = getimagesize($file_name); $r = $wid / $ht; if ($crop) { if ($wid > $ht) { $wid = ceil($wid-($width*abs($r-$width/$height))); } else { $ht = ceil($ht-($ht*abs($r-$w/$h))); } $new_width = $width; $new_height = $height; } else { if ($width/$height > $r) { $new_width = $height*$r; $new_height = $height; } else { $new_height = $width/$r; $new_width = $width; } } $source = imagecreatefromjpeg($file_name); $dst = imagecreatetruecolor($new_width, $new_height); image_copy_resampled($dst, $source, 0, 0, 0, 0, $new_width, $new_height, $wid, $ht); return $dst; } $img_to_resize = image_resize(‘path-to-jpg-image’, 250, 250);
