PHP Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 8192 bytes) in /home/example/public_html/vendor/intervention/image/src/Intervention/Image/Gd/Decoder.php on line 154

The error message indicates that the PHP script has exceeded the allowed memory limit. One solution is to increase the memory limit in the PHP configuration file (php.ini).

To do this, locate the php.ini file on the server and open it in a text editor. Look for the line that sets the memory_limit and increase the value to a higher number, such as 128M or 256M. Save the file and restart the web server.

If you don't have access to the php.ini file, you can try increasing the memory limit in the PHP script itself using the ini_set() function. However, this may not work if the server has a hard limit on memory usage.

Another solution is to optimize the image processing code to use less memory. One way to do this is to process the images in smaller batches instead of all at once. For example, you could process one image at a time and free up memory before processing the next image.

Here's an example of how to process images in batches:

$images = ['image1.jpg', 'image2.jpg', 'image3.jpg', 'image4.jpg', 'image5.jpg'];

foreach ($images as $image) {
    $rental_imagesname = $rentaldata->rental_name . '-' . rand(111, 9999) . '.' . $extension;
    $alternatelarge_image_path = 'imagesforthewebsite/rentalhouses/alternateimages/large/' . $rental_imagesname;
    $alternatemedium_image_path = 'imagesforthewebsite/rentalhouses/alternateimages/medium/' . $rental_imagesname;
    $alternatesmall_image_path = 'imagesforthewebsite/rentalhouses/alternateimages/small/' . $rental_imagesname;
    
    ini_set('memory_limit', '128M');
    
    $rental_imagestmp = Image::make($image);
    
    $rental_imagestmp->resize(1040, 1200)->save($alternatelarge_image_path);
    $rental_imagestmp->resize(520, 600)->save($alternatemedium_image_path);
    $rental_imagestmp->resize(260, 300)->save($alternatesmall_image_path);
    
    unset($rental_imagestmp);
    
    $rental_images = new Alternaterental_image();
    $rental_images->image = $rental_imagesname;
    $rental_images->house_id = $id;
    $rental_images->save();
}
