Check if webpage contains text

Question

I am getting a webpage using file_get_contents();:

$file = file_get_contents('http://example.com');

How do I check if the webpage contains the text 'hello' or 'bye'

$file = file_get_contents('http://example.com');
$exists = (strpos($file, 'hello') !== false) || (strpos($file, 'bye') !== false);
if ($exists !== false) {
    print 'Found';
}

@bobjomes Look at the code, have a guess! If you cannot work this out then maybe you need to find another career or hobby – RiggsFolly Aug 15 '16 at 16:23
@bobjomes it checks for both, if either hello or bye is found `Found` will get printed – Kamrul Khan Aug 15 '16 at 16:24
@user3360140 Actually its not fool proof as it stands, maybe if you read this you can work out a better solution ___Warning This function may return Boolean FALSE, but may also return a non-Boolean value which evaluates to FALSE. Please read the section on Booleans for more information. Use the === operator for testing the return value of this function.___ – RiggsFolly Aug 15 '16 at 16:25
Thats better so +1 – RiggsFolly Aug 15 '16 at 16:30
@RiggsFolly you are right. Thanks for pointing that out :) – Kamrul Khan Aug 15 '16 at 16:31
