php pages consume too much memory for processing

Solutions:

1, modify php.ini
Change memory_limit from 8M to 16M (or greater), and restart the apache service

2. Add ini_set(" memory_limit ", "100M") to the PHP file;

Note: for the normal use of other resources of the system, please do not set memory_limit too large, where -1 is unlimited

3. Modify the.htaccess document (provided the directory supports.htaccess)
Add a new sentence to the document: php_value memory_limit 16M(or greater)
