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

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

Change display_startup_errors = Off 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 for troubleshooting. if I open

Display_startup_errors = On appears

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

The solution is also 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

Open the php directory and start debugging ...... It took some time to find the root cause. if you encounter this problem, you can try the following solutions:

Open the php installation directory and edit the php. ini file. search for the following fields.

Extension = php_exif.dll. after finding it, add a semicolon to the front, as shown below:

; Extension = php_exif.dll, save and restart iis, and then access the php file to see if there is no memory location access failure.
