check if a word exists in a string

[juschillin]

I need to check to see if a word exists in a string. If its there then (do something), else(do something else).

I tried the explode function which would work if the word I was looking for was at the beginning, but it could be listed anywhere in a paragraph of about 20 words.

help please. This is the first time i have ever gotten stuck on php. I usually read some forums and figure it out. This seems like such a simple task, but I can't seem to get it right.

something along the lines of.

$word_search = "your_string";

if (preg_match("/your_word/", "$word_search")) {
do this;
) else {

do something esle;

}

That ought to do it.

$result = strpos($haystack, $needle);

if (is_integer($result)) { echo "You found a needle in the haystack!"; }

I think this would be the easiest way:

<?php
$text = "Paragraph one blah blah";
if (strstr($text, "word")) {
//do something
} else {
//do something
}
?>
