text list to array

[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]

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.php.net
http://www.google.com

Code Select Expand

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

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

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 Select Expand

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

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

Code Select Expand

$urlarray = file($myurls);

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()?

[Metho]

Well, with that trim thing, I tested it, and I don't get the newline return attached...so it might depend on php version, not sure.

Anyhow, if you've already got all of the url's in a VARIABLE, then yes, do an explode. When you said text I assumed you meant a text file. You'd do something like:

$urlarray = explode("\n", $myurls)
