My Experiments for Truth.

You can put the below code in a memory.php file and then view the result from browser by http://yourdomain.com/memory.php echo 'Current Memory Usage: '.number_format(memory_get_usage()/1024/1024,"2",".",",").' MB'."\r\n"; echo 'Current Memory Allocted: '.number_format(memory_get_usage(true)/1024/1024,"2",".",",").' MB'."\r\n"; echo 'Peak Memory Usage: '.number_format((memory_get_peak_usage()/1024/1024),"2",".",",").' MB'."\r\n"; echo 'Peak Memory Allocated: '.number_format((memory_get_peak_usage(true)/1024/1024),"2",".",",").' MB';

CURLOPT_RETURNTRANSFER is a simple way of copying a file from a remote server onto your own. However, if you’re downloading a large file you may hit memory limits because the entire contents of the download have to be read to memory before being saved. Note: Even if your memory limit is set extremely high, you would be putting unnecessary strain on your server by reading in a large file straight to memory. Instead you can write the download straight to a file stream using CURLOPT_FILE. Download file with cURL & PHP $url = 'http://www.example.com/a-large-file.zip'; $path = '/path/to/a-large-file.zip'; $fp = fopen($path, 'w'); $ch = curl_init($url); curl_setopt($ch, CURLOPT_FILE, $fp); $data = curl_exec($ch); curl_close($ch); fclose($fp);

You can find using this command as which user Apache is running # echo $(ps axho user,comm|grep -E "httpd|apache"|uniq|grep -v "root"|awk 'END {if ($1) print $1}')
