Find the occurrence of backslash in a string

Question

If my string is : aud\\ios, how do i check it out for the presence of \\ in it?

I tried using preg_match(\'\\\\\' , $string) but

Answer 1

I use this function a lot, you can easily check if a string contains

function StringContains($the_string,$contains)
{
    return strpos($the_string, $contains) !== FALSE;
}   

check it out: http://3v4l.org/LrDBd

of course you have to escape the backslash when calling the function like this StringContains('aud\ios','\\');
