Remove A Comma Off The End Of A String?

I want to remove the comma off the end of a string. As it is now i am using

$string = substr($string,0,-1);

but that only removes the last character of the string. I am adding the string dynamically, so sometimes there is no comma at the end of the string. How can I have PHP remove the comma off the end of the string if there is one at the end of it?

String Value Applies XYZ Except For Non-alpha-numeric Characters?

The script below takes the text already given to it and makes all the characters lowercase, makes the first letter uppercase, and then limits the string to no more then 36 total characters.

However I am having a problem when it takes a non-alpha-numeric entity such as & and cuts it off mid-way for example. This creates a parsing error which disables my page served as application/xhtml+xml.

$mail['shortsubject'] = ucwords(strtolower(substr($mail['subject'], 0, 36)));

So what I want to do is tell the page to do the same thing EXCEPT when encountering non-alpha-numeric entities such as the amperstamp.

RegEx Remove Space After Every Comma In String?

I have a string of names separated by commas. I'm exploding this string of names into an array of names with the comma as the delimiter. I need a RegEx to remove a white space(if any) only after the comma and not the white space between the first and last name.

So as an example:

$nameStr = "Sponge Bob,Bart Simpson, Ralph Kramden,Uncle Scrooge,Mickey Mouse";

See the space before Ralph Kramden? I need to have that space removed and not the space between the names. And I need to have any other spaces before names that would occur removed as well.

P.S.: I've noticed an interesting behavior regarding white space and this situation. Take the following example:

When not line breaking an echo like so:

$nameStr = "Sponge Bob,Bart Simpson, Ralph Kramden,Uncle Scrooge,Mickey Mouse";
$nameArray = explode(",", $nameStr);
foreach($nameArray as $value)
echo $value;

Remove Characters After String?

I have strings that looks like this:

John Miller-Doe - Name: jdoe
Jane Smith - Name: jsmith
Peter Piper - Name: ppiper
Bob Mackey-O'Donnell - Name: bmackeyodonnell

I'm trying to remove everything after the second hyphen, so that I'm left with:

Peter Piper
Bob Mackey-O'Donnell

So, basically, I'm trying to find a way to chop it off right before "- Name:". I've been playing around with substr and preg_replace, but I can't seem to get the results I'm hoping for...

Remove Characters From String?

(my first post was not clear and confusing so I've edited the question) I was studying string manipulation. You can use strlen() or substr() but cannot rely on other functions that are predefined in libraries. Given string $string = "This is a pen", remove "is" so that return value is "Th a pen" (including 3 whitespaces). Remove 'is' means if a string is "Tsih", we don't remove it. Only "is" is removed.I've tried (shown below) but returned value is not correct.

Remove First 4 And Last 5 Characters From A String?

I am using a CMS that automatically puts tags around content to dummy proof it for the end user. In this situation I am outputting a UL but the UL must retain a class so I want the CMS to just output the code starting with <li> and ending with </li> while the page itself contains the <Ul class="1234"> followed by the script output by the CMS. Currently the issue is that the CMS is automatically putting <ul>code</ul> making the page ultimately show <Ul class="1234"><ul>code</ul></ul>. What I want to accomplish is to remove the first 4 and the last five characters (<ul> and </ul>) from the string the CMS creates.Its portant to note that I can't use php to simply remove all the ul tags because in some cases there are nested uls that are output by the CMS and the uls in the middle of the code are necessary.Here is a sample of the script placed on the page to display the code from the CMS:
