ISAPI

PHPPHP

PHP executes as an external process.

Stable however there’s a challenge in performance.

IIS

PHP as In-process.

Speeds up performance but issues on non thread safe extensions.

IIS Execution ModelsIIS Execution Models

Extension to CGI allowing reuse of a process.

Advantages

Easy to Configure

Faster than CGI

More stable than

PHP on ISAPI

Can run non-

thread-safe

versions of PHP

Invokes a process for each request.

Advantages

Easy to Configure

Stable Execution

Disadvantages

Slow due to I/O

Overhead of

Process Creation

Loaded as extension in process.

Advantages

Better Performance

Disadvantages

Many PHP

Applications are

not Thread-Safe
