What to do if php has insufficient memory

The solution to insufficient php memory is to increase the maximum memory size of php. Specific method: [ini_set('memory_limit', '16M')]. The ini_set() function is used to set the value of php.ini, which takes effect when the function is executed. The setting becomes invalid after the script ends.
