I know this is simple, but I get asked it all the time! Here is how to search a string for another string using PHP.
PHP Code:
<?php
$x = "brown"; // searching for
$y = "The quick brown fox, jumped over the lazy dog"; // search in
$result = strpos($y,$x); // execute the search
if($result=== false) {
echo "The word brown was NOT found in the sentence.";
}
else {
echo "Yes! The word brown was found in the sentence.";
}
?>
Notice, that we searched for the existence of the word "brown" AKA $x in the sentence $y.
