php check regular string
//You should use a regex filter with preg_match who returns 1 or 0
// this filter works for most of cases
/* use this regex */ preg_match("/^[a-z ,.'-]+$/i", your_string);
if you want more regex filters you can make yours on 'https://regex101.com/'string match in php
You could use regular expressions as its better for word matching compared to
strpos, as mentioned by other users. A strpos check for are will also return
true for strings such as: fare, care, stare, etc. These unintended matches can
simply be avoided in regular expression by using word boundaries.
A simple match for are could look something like this:
$a = 'How are you?';
if (preg_match('/bareb/', $a)) {
echo 'true';
