Where is PHP strcmpi?

Aren't all PHP functions named the same as in C/C++?

No. Many PHP functions do in fact have the same name as their C/C++ counterparts. Regardless, strcmpi and stricmp are not standard C/C++ functions.

The C/C++ functions strcmpi (or stricmp or _strcmpi), have no identically named function in PHP.

However, the equivalent binary-safe case-insensitive string comparison function in PHP is called strcasecmp. It is defined as follows:


int strcasecmp ( string str1, string str2 )

Returns < 0 if str1 is less than str2 ; 
> 0 if str1 is greater than str2 , 
and 0 if they are equal.

The strcasecmp() function is available in PHP 3.0.2 or higher, PHP 4, and PHP 5, so you should have no trouble using this in your PHP scripts.

I hope this information helps your PHP web development efforts!
