match in php code example

Example 1: preg_match in php

<?php
//Syntex : int preg_match( $pattern, $input, $matches, $flags, $offset)
  
// Declare a variable and initialize it 
$str = "Check For Testing."; 
  
// case-Insensitive search for the word "Check" 
if (preg_match("/\bCheck\b/i", $str, $match))  
    echo "Matched!"; 
else
    echo "not matched";   
  

// Output : Matched
?>

Example 2: string match in php

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

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

Example 3: php regex

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

Example 4: 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';
}
