Solution to insufficient php memory

Sometimes when we run the php program again,

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

# will appear ##The reason for this error: After making sure that it is not caused by the program (such as an infinite loop), it is because the maximum memory consumed by the PHP page is 8M by default (can be seen in the PHP ini file),

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 larger), restart the apache service

2. Add in the PHP file ini_set('memory_limit','**M'); Note: For the normal use of other resources of the system, please do not set the memory_limit too large, where -1 means no limit

3. Modify the .htaccess document (The premise is that the directory supports .htaccess) Add a new sentence in the document: php_value memory_limit 16M (or greater)
