[SOLVED] Could someone help me understand this ===0

[natepizzle]

I understand '===0' means is exactly the same but i don't understand the return statement with that on the end. I saw this code snippet at http://www.jonasjohn.de/snippets/php/starts-with.htm and its dated back in 2007 so maybe its just old and not UTD with php 5. Maybe there is an implied if statement there saying return this line only if it is exactly equal to 0. Thanks for any help.

 

[cod]

 

function StartsWith($Haystack, $Needle){

    // Recommended version, using strpos

    return strpos($Haystack, $Needle) === 0;

   

}

You are correct it is an implied if statement, but I would consider it extreme shorthand and not considered valid syntax. Basically it will return 0 if the function evaluates to TRUE. Else it will not return anything.
