Troubleshooting of invalid access to memory locations The configuration environment is as follows:

Solve the "invalid memory location access" errorMethods and steps(Some invalid debugging steps are skipped ..)

1. enable IIS errors. no error cause is found!

2. check for IIS Extensions. The ISAPI, php. ini, and Mysql configurations, and the corresponding installation directory ACLs permissions are all correct.

3. reclaim IIS process. the error still shows "invalid memory location access "....

4. open display_startup_errors = On in php. ini. The problem is finally found... (Note: If you open display_startup_errors of php. ini, if php has an error, a prompt will be displayed, and there will be a record in the event viewer. If it is set to display_startup_errors = Off, no prompt will be displayed)

V. Warning

Cannot load module 'sqlite 'because required module 'pdo' is no loaded

The above error message was finally found. Probably because SQLite desktop database support is enabled in the php. ini configuration, but the related pdo mode is not enabled, the pdo module loading fails .....

6. the solution is also very simple. because the php_sqlite.dll file is not loaded when it is loaded, the system prompts that the access to the memory location is invalid when running the phpinfo () function. Find the php. ini configuration file and remove the semicolon before "; extension = php_pdo.dll". extension = php_sqlite.dll

Then, reclaim the IIS application pool process and solve the problem ....

Hoho, I hope it will be helpful to my friends who have encountered this problem...
