If you just want to do a simple replacement and don’t mind where the word might appear, you would be better off using PHP’s str_replace() function:

1
2
3
4
$word = "foo";
$replace = "bar";
$string = "<img src="hello.png" alt="This is a nice foo image" /><p>This is a nice foo string</p>";
echo str_replace($word, $replace, $string); // <img src="hello.png" alt="This is a nice bar image" /><p>This is a nice bar string</p>
