Php check string

Strpos in php

<?php
$mystring = 'abc';
$findme   = 'a';
$pos = strpos($mystring, $findme);

// Note our use of ===.  Simply == would not work as expected
// because the position of 'a' was the 0th (first) character.
if ($pos === false) {
    echo "The string '$findme' was not found in the string '$mystring'";
} else {
    echo "The string '$findme' was found in the string '$mystring'";
    echo " and exists at position $pos";
}
?>

Php check string

// if you want to test content of a string to match a model

//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/'
