[SOLVED] Add Numbers in PHP

[Sangha-08]

I've currently got a basic php script to format the query, I'm new to php. Here is the script that I have:

 

$titlea = $_GET['title'];
$titlea= str_replace ("-", " ", $titlea);
$titlea = ucwords($titlea); 
$titlea= str_replace (" ", "_", $titlea);
echo($titlea);

 

This converts the query "php-freaks-is-awesome" to "Php Freaks Is Awesome"

 

But, If i send it a query, something like "show-search-1" I want it to produce an output of "show-search-2" which is basically +1 to the number in the query, does anybody know how I can do this? I've looked everywhere but I am unable to do this.

 

Could someone tell me how to do this?

 

Thanks.

$a = "show-search-1";
$a++;
echo $a;

 

wait... this will only work for digits from 0 to 8

$a = "show-search-1";
$a++;
echo $a;

 

wait... this will only work for digits from 0 to 8

 

is there any other way, btw, I want it to do +1 to every number in the script... Ive searched google for, well, about 2 hours. I still cant get anything..

Is the number always at the end of the string, and after a dash ( - ) ?

Nope, there can be (sometimes) more characters after the number

[Mchl]

ok...

but will there always be only one number in a string?

Yeah, there will always just be one number, but not one digit number, if you know what I mean.

 

omg, thanks for all your help

$a = "show-search-1-foo";
$array = explode("-",$a);
foreach($array as $key => $value) {
if (is_numeric($value)) {
	$array[$key] = ((int)$value)+1;
}
}
$b = implode("-",$array);
echo $b;
