How to increase memory limit for file_get_contents of 5.8Gbyte zipfile

Question

I am trying to backup 5.9gbyte files in php. But my code is memory limit. file_get_contents function is not reading big file such as 3G, 5G zip file. So i have memory error. So i tried to split file

enter code here
    $in = @fopen($file, "r");
    $path = str_replace($source . '/', '', $file);
     while ($buff = fread($in, 4096)) {
     $zip->addFromString($path, $buff);
    }

But this is error about backup of big file when create zip file from big file directory. Thanks.

wait, you're zipping 5.8gb with php? Please... do `exec('zip backup.zip file.a file.b file.z')` or a recursive. Don't use php for the zipping, use the native tools. Hell even install 7zip if you're running on windows and use the command line part of it. — Tschallacka, Nov 20 '17 at 10:13

thanks for your reply, how? – Jincowboy Nov 20 '17 at 10:11
Top of the php file that you read your data. – pr1nc3 Nov 20 '17 at 10:12
try upload_max_filesize in case post does not work. You can put any value you want after `=` so i suggest you don't keep it unlimited (for security reasons) – pr1nc3 Nov 20 '17 at 10:14
thanks for your reply, I am trying :ini_set('post_max_size',0); – Jincowboy Nov 20 '17 at 10:17
That's an option or you can change it straight inside your .ini file. – pr1nc3 Nov 20 '17 at 10:19
I am trying again this.:ini_set('post_max_size',0); ini_set('upload_max_filesize ','5000M'); $zip->addFromString(str_replace($source . '/', '', $file), @file_get_contents($file)); – Jincowboy Nov 20 '17 at 10:20
but it says error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 144227184 bytes) – Jincowboy Nov 20 '17 at 10:20
Ok locate your php.ini file and look for `post_max_size` and change it there. Careful to select the CORRECT php.ini. This will solve your problem. – pr1nc3 Nov 20 '17 at 10:21

thanks, yea. i created php.ini of wp plugin backup php directory. and post_max_size=50000M it is not working: allowed memory error,sir – Jincowboy Nov 20 '17 at 10:26
I am trying again: upload_max_filesize = 10000M post_max_size = 20000M memory_limit = 30000M file_uploads = On max_execution_time = 1800 – Jincowboy Nov 20 '17 at 10:28
Did you try to set it to unlimited? – pr1nc3 Nov 20 '17 at 10:28
it is error also: Allowed memory size of 268435456 bytes exhausted (tried to allocate 144227184 bytes) – Jincowboy Nov 20 '17 at 10:28
i want 5gbyte zip file creation of file directory – Jincowboy Nov 20 '17 at 10:29
You said you are using WP. try this `define( 'WP_MAX_MEMORY_LIMIT', '10G' );` or just `define( 'WP_MEMORY_LIMIT', '10G' );` – pr1nc3 Nov 20 '17 at 10:31
thanks, but where should write this? – Jincowboy Nov 20 '17 at 10:34
Top of the file or find this fields in your .ini file and change them – pr1nc3 Nov 20 '17 at 10:35
thanks, i tried again. but error. and only 372MB backup zip file creation – Jincowboy Nov 20 '17 at 10:38
Try convert it to MB and add it as MB number. Also your execution time is 3 minutes make sure you don't crush there. – pr1nc3 Nov 20 '17 at 10:38
thanks for your lots of reply. but it is not working in local wp plugin of wordpress – Jincowboy Nov 21 '17 at 01:07
