PHP detection to obtain memory information_PHP tutorial

PHP can also detect and obtain the memory information of Windows, and the code is quite simple. I discovered it accidentally and thought it could be used in the future, so I would like to share it with you.

This code will get the total memory, initial usage and other memory information:

　01

　02echo "Initial: ".memory_get_usage()." Byte n";

　03for ($i = 0; $i < 100000; $i++) {

　04 $array []= md5($i);

　05}

　06for ($i = 0; $i < 100000; $i++) {

　07 unset($array[$i]);

　08}

　09echo "Final: ".memory_get_usage()." Byte n";

　10echo "Total memory: ".memory_get_peak_usage()." Bytes n";

　11?>

Example of running results:

Initial: 66104 bytes Final: 590600 bytes Total memory: 12591704 bytes
