checking for a value in a string...

dv6cougar

what i have is a website url field right...

problem is that some people put www.whatever.com and not http://www.whatever.com , while some do ti right with [url]http://[/url] first.

now i can use this...

str_replace("www.", "http://www.", $whatever_string);

but then when someone did it right and did use [url]http://[/url] i'm gonna get http://http://www.whatever.com

so i was hoping there was a function that checks for a value in a string... so i could do this....

//where str_find stands for the function i'm looking for 
//and site_url = the url i need to fix if neccessary
$http = str_find("http://", $site_url);

if($http == "yes") {
//do nothing, the [url]http://[/url] exist
} else {
//http:// is not existant, make it
$site_url = str_replace("www.", "http://www.", $site_url);
}

any ideas? thanks alot 😃

There is a smooth way with preg_match, but Im to tired (2am)

Do this.
Replace www. with http://www. as you did it

then make a replacement
http://http://www. to http://www.

Hey, its dirty, but it works 🙂
Else goto search or google and enter preg_match URL or something.

haha, that would work

i'll check google though, thanks 😃

Hey, you asked for something that works, and it WORKS, so whats the problem? ;-) ;-D

Gosh, I need to get some sleep before I actually start coding like this.

Also you could replace "a href=" with "a target="blank" href=" ... just a thought. But then you would have to replace "a target="blank" href="http://this.server" with a href again, since its local. Aww. my head hurts now. Go google for eregi_replace OR preg_match and URL replacements 🙂

I would highly recommend that you DON'T use regular expressions unless it is absolutely essential.

Use str_replace instead, it is MUCH faster.

= = = = = = = = = = =

To check the existence of a substring in a string, use the following:

if (strstr('http://www.phpbuilder.com','http://')) {
	echo "Substring found."
} else {
	echo "Substring not found."
}

You could also use stristr() for case-insensitive searches.

= = = = = = = = = = =

Here is my suggestion.

<?
$string='http://'.str_replace('http://','',$string);
?>

Hope this helps,
cdbsi. 😃

that's probably the best idea 🙂

sometimes the unlogical works best 😃
