I'm trying to find a function that will check / search for a value inside of a string inside of a variable. Similar to in_array().

It returns the index of a searched string, or false if the searched string isn't found.
Say I wanted to find 'York' inside of 'New York'
<?php
$string = 'New York';
$find = 'York';
strpos($string, $find); // Would return 4
echo strpos($string, $find) ? 'Found it!' : 'Did not find it.'; // Would echo 'Found it!'
Is this what you mean?

Python Development Techdegree Student 22,377 PointsI ended up doing something like this:
<?php
$find = "Full DOB available and matched input";
$test = strpos($response, $find);
if ($test) {
echo "You have passed age verification.";
} else {
echo "You have failed age verification";
}
?>
I don't really understand what is going on here:
<?php
echo strpos($string, $find) ? 'Found it!' : 'Did not find it.'; // Would echo 'Found it!'
?>
I'm assuming that is some shorthand syntax for testing if the expression is true?
