string match php code example

Example 1: php check if string contains word

$myString = 'Hello Bob how are you?';
if (strpos($myString, 'Bob') !== false) {
    echo "My string contains Bob";
}

Example 2: if part of stringp ph

$a = 'How are you?';

if (strpos($a, 'are') !== false) {
    echo 'true';
}

Example 3: 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";
}
?>

Example 4: string match in php

//str_contains ( string $haystack , string $needle ) : bool

if (str_contains('Foo Bar Baz', 'Foo')) {
  echo 'Found';
}

Example 5: php regex

preg_match('/(foo)(bar)(baz)/', 'foobarbaz', $matches, PREG_OFFSET_CAPTURE);

Example 6: 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';
}
