The problem with this is you can accomplish essentially the same thing in userland if you know how to write a good "compiled regex" ... Calling the pcre functions in C land gains you very little. An extension is totally unnecessary. |

Using pure PHP, you need to load a lot of class files. and function calls, method calls, hash find are pretty slow in pure PHP.
- First of all, while using C extension, you don't need to reload these php class files again and again. it reduces the class loading overhead.
- Seconds, looping and string comparison is pretty fast in C. it's because in pure PHP, it duplicates the string when calling functions/methods in the runtime.
- Third, there are a lot of spaces to optimize the code in C rather than in pure php.
- Last, pure PHP consumes a lot of memory, but in C extension, the memory footprint is pretty small.
