Sometimes when we run php again, it will appear

Allowed memory size of 8388608 bytes exhausted (tried to allocate 1298358 bytes)

The reason for this error: to ensure that it is not the cause of the program (such as endless loop), it is due to the default maximum memory consumption of php pages is 8M (you can see it in PHP ini) ,

If the file is too large or the image is too large, the above error will occur when reading.

Solution:

1. Modify php.ini to change memory_limit from 8M to 16M (or greater), restart apache service

2. Add ini_set ('memory_limit','** M') to PHP file; Note: For normal use of other system resources, please do not set memory_limit too large, where-1 is unlimited
