PHP - Removing Certain Text With Php?

Ok i have just installed anope irc services on my irc network and they use MySQL databases.

Through this, I can use the same info/passwords to link user/website accs.

However it stores passwords as md5:someHashHere

How would i get a php script to remove the md5: from the start, or would it just be easier checking against md5:$md5(enteredpassword)?

I need to remove some text from a php variable.

right now

$testv = <span id="sobi2Details_field_street">www.google.com</span>

I need to remove the <span id="sobi2Details_field_street"> and the </span> so im left with

$testv = www.google.com

Hello,

I have a field in which when a user types something into it, it saves it into a table in my SQL. But is it possible to remove a particular phrase from the field if the user enters it.

Example:

I have a text field that says 'please enter your website domain here'. The user then enters 'www.domain.com'. Is it possible for PHP to remove the 'www.' and only save the 'domain.com' to my SQL (bearing in mind that not all users may enter www.)

Here is the code for the text field:

Code: [Select]
<input name="website_name" type="text" class="text-box" id="website_name" value="<?php echo $website_name; ?>" size="24" />
Here is the code for the _POST:

if(isset($_POST['send']))
            {
$database->updateUserField($session->username, "website_name", $_POST['website_name']);
}

(the code so far all works fine - I just want to add an extra 'variable', if you will, to the code)

Thanks for your help!!

Merry xmas and happy new in advance to you all.

I have a web form where user submit an ad. Everything is working just fine. However there is a field name brief. The brief field is where user add info about their ad. Now people are including web url, phone numbers and email address in this field which make the ad look like spam.

In the code there is already a function that check if they have entered their email address in the email field. I want to add a function to the check field to include the brief field. The function should either automatically delete any phone number/email addr/web url or replace with with my website name if detected in the brief field.

Your help will be highly appreciated.
