Question about strpos: how to get 2nd occurrence of a string?

Question

I understand that this function will get the first occurrence of the string.

But what I want is the 2nd occurrence.

How to go about doing that?

Answer 1

function substr_Index( $str, $nth ){
    $str2 = '';
    $posTotal = 0;
    for($i=0; $i < $nth; $i++){

        if($str2 != ''){
            $str = $str2;
        }

        $pos   = strpos($str, ':');
        $str2  = substr($str, $pos+1);
        $posTotal += $pos+1;

    }
    return $posTotal-1;
}


echo substr($mystring, substr_Index( $mystring , 2) );

Function returns position of nth delimiter.

Second parameter of substr_Index must be bigger than 0;

To find second occourance use substr_Index( $mystring , 2)
