text list to array

(1/2) > >>

Anguz:
if I have a text with urls, one per line, how can they be put into an array?

horus:
I usually use "explode",

explode ( string separator, string string [, int limit]))

checkout php.net [nofollow]

Metho:
This'll go right off the text file, auto put into an array based off of endlines. Very easy. And yes, php.net is your friend.
myurls.txt
----------------
http://www.simplemachines.org
http://www.yabbse.org
http://www.php.net
http://www.google.com
---------------------


--- Code: ---<?PHP
$urlarray = file ('myurls.txt');
echo "$urlarray[2]";
?>
--- End code ---

Will return http://www.php.net. Neato, huh? :D

I was thinking about that, but wasn't sure how

sweet! I didn't know the file() function!

http://mx2.php.net/manual/en/function.file.php
it says there that the newline is kept at the end of each value of the array... so if I want to use the url in a link, I should trim() it, right? like:


--- Code: ---echo '<a href="' . trim($urlarray['2']) . '">php.net</a>';
--- End code ---

Anguz:
hmm... what if the text is in a variable because it was retrieved from the db? like:


--- Code: ---$urlarray = file($myurls);
--- End code ---

the name of the function doesn't suggest it would work, that's why I ask...

if it doesn't, then, is there a function like this one that'd work with a variable? or would I have to go with explode()?
