1. memory_get_usage:此函数返回当前PHP脚本所使用的内存量。它返回的值以字节为单位,可以通过除以1024来将其转换为KB、MB或GB等更为常见的单位。 “`php $memoryUsage = memory_get_usage(); echo “Current memory usage: ” . $memoryUsage . ” bytes
Description Hi! We recently upgraded to PHP 8.1 and now we sporadically get this kind of new errors: Failed to set memory limit to 536870912 bytes (Current memory usage is 870318080 bytes) The problem is, the memory usage cannot be that ...
