Error importing image: Allowed memory size

Question

I’m using a simple script to crop the image, while cropping some images it gives this error:

Allowed memory size of 268435456 bytes exhausted (tried to allocate 155648 bytes) in /home/site/public_html/admin/controller/photo.php on line 65

The strange thing is that the image is only 65kb, does anyone know what it might be? There’s a way I can generate a more detailed log?

below the script and the commented line 65:

//RECORTAR E IMPORTAR AS FOTOS NO FTP ****************************************

        list($width, $height, $type, $attr) = getimagesize($photo_url);

Good morning, you can check your php.ini the directive memory_limit change to something around 1024M or more.

Some returns referring to memory limit:

PHP: Fatal Error: Allowed Memory Size of 8388608 Bytes Exhausted - 8 MB
PHP: Fatal Error: Allowed Memory Size of 16777216 Bytes Exhausted - 16 MB
PHP: Fatal Error: Allowed Memory Size of 33554432 Bytes Exhausted - 32 MB
PHP: Fatal Error: Allowed Memory Size of 67108864 Bytes Exhausted - 64 MB
PHP: Fatal Error: Allowed Memory Size of 134217728 Bytes Exhausted - 128 MB
PHP: Fatal Error: Allowed Memory Size of 268435456 Bytes Exhausted - 256 MB
PHP: Fatal Error: Allowed Memory Size of 536870912 Bytes Exhausted - 512 MB
PHP: Fatal Error: Allowed Memory Size of 1073741824 Bytes Exhausted - 1 GB

As you can see, yours is at 256MB.

You can also check these other directives that are also related to file uploads (but the first solution above already solves your problem):

upload_max_filesize
file_uploads
upload_max_filesize
max_file_uploads
post_max_size
max_input_time

Remembering that after making this change in your php.ini your apache must be restarted to work.

If you want to put the solution in your file use the code below. But I recommend changing php.ini.

<?php
    ini_set('memory_limit', '1024M'); // no caso usando 1G

I hope I’ve helped
