How to check if a string ends with another string in PHP

This snippet will enable you to check if a string ends with a certain string. Particularly very handy when checking filetypes, like is something a jpg or not.
The third parameter is optional, if set to true then the comparison will be case-specific.

function endsWith($haystack,$needle,$case=true) {
    //If its case specific
    if($case){
      return (strcmp(substr($haystack, strlen($haystack) - strlen($needle)),$needle)===0);
    }
    return (strcasecmp(substr($haystack, strlen($haystack) - strlen($needle)),$needle)===0);
}

Sample Code

if(endsWith("hello.jpg", '.jpg')) {
    print "true";
}
else {
    print "false";
}
//True

Here strcmp plays major role which compare two strings and returns < 0 if string1 is less than string2; > 0 if string1 is greater than string2, and 0 if they are equal.
