PHP "invalid memory location access" _ PHP Tutorial-php Tutorial

PHP "invalid memory location access ". The newly configured PHP environment or configuration changes have just been made, such as the newly loaded DLL extension and webpage access, may cause invalid access to the memory location. . The main reason is that the DLL extension loads the PHP environment with the new configuration, or you have just made configuration changes, such as the newly loaded DLL extension and accessing the page, "the access to the memory location is invalid ." . The main reason is that the DLL extension fails to load.

We need to find the DLL file to load. The troubleshooting method is as follows:

Change display_startup_errors = Off in php. ini to display_startup_errors = On.

When you access the php page, a php error dialog box will pop up on the server. you can clearly see which dll file fails to be loaded, and sometimes multiple dll files fail to be loaded, you need to annotate php with a semicolon (;) first. ini prompts that the dll will be accessed again and again.

After the problematic dll is commented out with a semicolon (;), php can run normally.

Handler process, delete the previously loaded dll, re-add the new dll, and then restart IIS.
