This function will take an parse_url array, and return a URL.
You may be wondering what the point of it is, as (normally) if you have a parse_url array, you have the URL. I was creating a PHP script to grab news from a site (using preg_match_all()) and produce an Atom feed. An Atom feed is XML, therefore must be well-formed, so all the parts of a URL must be properly escaped. |
Indeed, this is very useful for that. Its also good for script like that one topsite (Gold something? I don't remember the name.) that stored urls all broken up by parse_url() (For some pointless reason.) And they manually put the URLs back together for redirection, but this would reduce their code alot by using a simple, useful function. Thanks for this.
