match word in string

[dreamwest]

Whats the quickest way to find a word in a string and wrap <b> tags around it?

 

$search =  "php web";
$striing = "PHP is the web scripting language of choice";

 

 

Basically im looking for the output to be :

"<b>PHP</b> is the <b>web</b> scripting language of choice"

If it's only those two specific words. you can do

<?php
$search = array('PHP','web');
$replace = array('<b>PHP</b>','<b>web</b>');
$str = "PHP is the web scripting language of choice";
$new = str_replace($search,$replace,$str);
echo $new;
?>

If you get your $search word(s) into a regular expression OR | format -

<?php
$search =  "php|web";
$string = "PHP is the web scripting language of choice";

$string = preg_replace("/($search)/i",'<b>\1</b>',$string);

echo $string;
?>
