It appears that imagecrop() will output a black line along the bottom the resulting image until version 5.6.12. Your only choices are to upgrade PHP or use imagecopyresampled().

Use imagecopyresampled to crop your image instead, and it should work correctly in PHP 5.5+ without any black lines.

<?php
// Desired function call.
$cropped = imagecrop( $image, array( 'x' => $x, 'y' => $y, 'width' => $width, 'height' => $height ) );

// Equivalent function which works in both PHP pre 5.6.12 and 5.6.12+.
$cropped = imagecreatetruecolor( $width, $height );
imagecopyresampled( $cropped, $image, 0, 0, $x, $y, $width, $height, $width, $height );
?>

To get the center crop of a image in php:

           
$new = imagecreatefromjpeg($uploadedfile);

    $crop_width = imagesx($new);
    $crop_height = imagesy($new);
               
            $size = min($crop_width, $crop_height);
           
           
            if($crop_width >= $crop_height) {
            $newx= ($crop_width-$crop_height)/2;
           
            $im2 = imagecrop($new, ['x' => $newx, 'y' => 0, 'width' => $size, 'height' => $size]);
            }
            else {
                $newy= ($crop_height-$crop_width)/2;
           
                $im2 = imagecrop($new, ['x' => 0, 'y' => $newy, 'width' => $size, 'height' => $size]);
                }
           
               
    imagejpeg($im2,$filename,90);
