Finding a word within a string

By James Middleton - Added 11th of January 2009

Now that we know how to hold words as variables or 'strings', let's see if we can use an 'if' statement to find a certain word within a given string:


/// The following uses a 'Needle in a haystack' principle.
$word = "PHP";
$sentence = "PHP is such an elegant language.";

if(strstr($sentence ,$word))
{
echo "Found a PHP!";
}


The native PHP strstr function looks for the '$word' value in the '$sentence' string.

The Above example is case sensitive. If you wanted to perform this search as a case insensitive, substitute 'strstr' with 'stristr'.
