ImageCreateTureColor php占用了太多内存

我有一个php代码，它通过ajax调用获取它的值。这些值由裁剪模块提供，用户使用裁剪模块来裁剪图像

<?php

ini_set('Memory_limit', -1);

$imgUrl = $_POST['imgUrl'];
// original sizes
$imgInitW = $_POST['imgInitW'];
$imgInitH = $_POST['imgInitH'];
// resized sizes

$imgW = $_POST['imgW'];
$imgH = $_POST['imgH'];
// offsets
$imgY1 = $_POST['imgY1'];
$imgX1 = $_POST['imgX1'];
// crop box
$cropW = $_POST['cropW'];
$cropH = $_POST['cropH'];
// rotation angle
$angle = $_POST['rotation'];

$jpeg_quality = 100;
$uniquename=uniqid().time();
$output_filename = "croppedimages/".$uniquename;
// uncomment line below to save the cropped image in the same location as the original image.
//$output_filename = dirname($imgUrl). "/croppedImg_".rand();

$what = getimagesize($imgUrl);

switch(strtolower($what['mime']))
{
    case 'image/png':
        $img_r = imagecreatefrompng($imgUrl);
        $source_image = imagecreatefrompng($imgUrl);
        $type = '.png';
        break;
    case 'image/jpeg':
        $img_r = imagecreatefromjpeg($imgUrl);
        $source_image = imagecreatefromjpeg($imgUrl);
        error_log("jpg");
        $type = '.jpeg';
        break;
    case 'image/gif':
        $img_r = imagecreatefromgif($imgUrl);
        $source_image = imagecreatefromgif($imgUrl);
        $type = '.gif';
        break;
    default: die('image type not supported');
}


//Check write Access to Directory

if(!is_writable(dirname($output_filename))){
    $response = Array(
        "status" => 'error',
        "message" => 'Can`t write cropped File'
    );  
}else{

    // resize the original image to size of editor
    $resizedImage = imagecreatetruecolor($imgW, $imgH);
    imagecopyresampled($resizedImage, $source_image, 0, 0, 0, 0, $imgW, $imgH, $imgInitW, $imgInitH);
    // rotate the rezized image
    $rotated_image = imagerotate($resizedImage, -$angle, 0);
    // find new width & height of rotated image
    $rotated_width = imagesx($rotated_image);
    $rotated_height = imagesy($rotated_image);
    // diff between rotated & original sizes
    $dx = $rotated_width - $imgW;
    $dy = $rotated_height - $imgH;
    // crop rotated image to fit into original rezized rectangle
    $cropped_rotated_image = imagecreatetruecolor($imgW, $imgH);
    imagecolortransparent($cropped_rotated_image, imagecolorallocate($cropped_rotated_image, 0, 0, 0));
    imagecopyresampled($cropped_rotated_image, $rotated_image, 0, 0, $dx / 2, $dy / 2, $imgW, $imgH, $imgW, $imgH);
    // crop image into selected area
    $final_image = imagecreatetruecolor($cropW, $cropH);
    imagecolortransparent($final_image, imagecolorallocate($final_image, 0, 0, 0));
    imagecopyresampled($final_image, $cropped_rotated_image, 0, 0, $imgX1, $imgY1, $cropW, $cropH, $cropW, $cropH);
    // finally output png image
    //imagepng($final_image, $output_filename.$type, $png_quality);
    imagejpeg($final_image, $output_filename.$type, $jpeg_quality);
    $response = Array(
        "status" => 'success',
        "url" => $output_filename.$type,
    );

}
print json_encode($response);

如果你检查你的
php.ini
文件，你会得到它的
内存限制
不是
内存限制

请参阅：

因此，将
ini\u集（'Memory\u limit'，'-1'）
更改为
ini\u集（'Memory\u limit'，256）
或
ini\u集（'Memory\u limit'，'-1'）
您是自托管还是付费提供商？正在使用localhost，但可能会将此模块添加到一个实时网站。我将使用其他图像处理库。此库用于学习。您是否正在运行suhosin？GD必须将整个图像加载到内存中才能使用它。您可能会更幸运地使用没有此限制的。不，我没有使用@mkaatman
