Querystring参数explode str_replace数组仅适用于1个分隔符

Question

I am using a explode and str_replace on the get parameter of the query string URL. My goal is to split the strings by certain characters to get to the value in the string that I want. I am having issues. It should work but doesn't.

Here are two samples of links with the query strings and delimiters I'm using to str_replace.

http://computerhelpwanted.com/jobs/?occupation=analyst&position=data-analyst

as you can see the URL above parameter is position and the value is data-analyst. The delimiter is the dash -.

http://computerhelpwanted.com/jobs/?occupation=analyst&position=business+systems+analyst

and this URL above uses same parameter position and value is business+systems+analyst. The delimiter is the + sign.

The value I am trying to get from the query string is the word analyst. It is the last word after the delimiters.

Here is my code which should do the trick, but doesn't for some reason.

$last_wordPosition = str_replace(array('-', '+')," ", end(explode(" ",$position)));

It works if the delimiter is a + sign, but fails if the delimiter is a - sign.

Anyone know why?

Answer 1

You have things in the wrong order:

$last_wordPosition = end(explode(" ", str_replace(array('-', '+'), " ", $position)));

You probably want to split it up so as to not get the E_STRICT error when not passing an variable to end:

$words = explode(" ", str_replace(array('-', '+'), " ", $position));
echo end($words);

Or something like:

echo preg_replace('/[^+-]+(\+|-)/', '', $position);
