Question

Basically I have the code:

echo strcasecmp('hello', ' ') ? 'true' : 'false';

I don’t quite understand, I’m expecting the result here to be false and not true because the string aren’t equal…

Is there another better way to compare strings in a case INSENSITIVE way?

Answer 1

From http://php.net/manual/en/function.strcasecmp.php

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.

You need to do it like

echo strcasecmp('hello', ' ') == 0 ? 'true' : 'false';
