How to check if text exist in a string?

[t_machine]

Hi, I am wondering if someone could help with this. I would like to check if a word exist in a string and if yes do something.

 

example:

 

$string = 'This website is cool';

 

How to I check if the word 'website' exists in that string?

 

Thanks

try this:

<?php

$string = 'This website is cool';
$find = 'website';

if(strstr($string, $find)){
echo "This has $find in it!";
}else{
echo "This does not have $find in it!";
}

?>

Thank you both very much for the help Either of eregi or cmgmyr's example works great for what I needed.

I don't want to be annoying or something (because the problem is already solved), but I think it's better to use strpos().

 

From the manual, the strstr() function:

Note:  If you only want to determine if a particular needle  occurs within haystack, use the faster and less memory intensive function strpos() instead.

 

And here's how you do it (allow me to use your example, cmgmyr):

<?php

$string = 'This website is cool';
$find = 'website';

if(strpos($string, $find) !== FALSE){
echo "This has $find in it!";
}else{
echo "This does not have $find in it!";
}

?>

 

 

Orio.
