PHP Fatal error: Allowed memory size
I am receiving the following error whilst trying to download huge size file from live php serve
php Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 1705654 bytes)
Here are some options to increase PHP memory allocation

Here are some options to increase PHP memory allocation
- If you can edit or override the system php.ini file, increase the memory limit. For example, memory_limit = 256M
- If you cannot edit or override the system php.ini file, add php_value memory_limit 256M to your .htaccess file
- If you cannot edit or override the system php.ini file, add php_value memory_limit 256M to your .htaccess file
You can increase the memory allowed to php script by executing the following line above all the codes in the script
ini_set('memory_limit','-1');
But is never good. If you want to read a very large file, it is a best practise to copy it bit by bit. Try the following code for best practise.
$path = 'path_to_file_.txt';
$file = fopen($path, 'r');
$len = 1024; // 1MB is reasonable for me. You can choose anything though, but do not make it too big
$output = fread( $file, $len );
while (!feof($file)) {
$output .= fread( $file, $len );
}
fclose($file);
echo 'Output is: ' . $output;
