Find, replace and print only a specific word from a string

hi,
I have this string:

$mystr = "<ul>bla bla bla bla...</ul>";

Code (markup):

I want to find the "</ul>" and replace it with "</table>" but to print only this and to exclude any other text before or after that. how i can do this?

Thank in advance.

 

So you basically want to get rid of <ul>bla bla bla bla...</ul>

 

start with str_replace(). everything else you need is here http://php.net/manual/en/ref.strings.php​

 

Best way to solve this is with the following code:

$mystr = "<ul>bla bla bla bla...</ul>";
$mystr = str_replace(array('<ul>', '</ul>'), array('<table>', '</table>'), $mystr);

PHP:

Or if you only want the </ul>:

$mystr = "<ul>bla bla bla bla...</ul>";
$mystr = str_replace('</ul>', '</table>', $mystr);

PHP:

 

You can use following function to find and replace

<?php
function str_replace_once($search, $replace, $subject) {
    $firstChar = strpos($subject, $search);
    if($firstChar !== false) {
        $beforeStr = substr($subject,0,$firstChar);
        $afterStr = substr($subject, $firstChar + strlen($search));
        return $beforeStr.$replace.$afterStr;
    } else {
        return $subject;
    }
}
?>
