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";
}
?>string match in php
//str_contains ( string $haystack , string $needle ) : bool
if (str_contains('Foo Bar Baz', 'Foo')) {
echo 'Found';
}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('/\bare\b/', $a)) {
echo 'true';
