Writing array to a file

[devWhiz]

<?php
$file = 'test.txt';
$lastfm = file_get_contents('http://www.last.fm/group/Rishloo/members');
preg_match_all('/id="r4_([\d]+)">/', $lastfm, $matches);
file_put_contents($file, $matches[1]);


sleep(100000);

?>

 

That puts the array in a file but I need each value on a new line but it bunches it all up..

 

this just puts "Array" in file

 

 

<?php

$file = 'test.txt';

$lastfm = file_get_contents('http://www.last.fm/group/Rishloo/members');

preg_match_all('/id="r4_([\d]+)">/', $lastfm, $matches);

file_put_contents($file, $matches[1]."\n");

 

 

sleep(100000);

 

?>

 

what do I need to do to print all of the values on a new line?

 

Thanks

You need to convert the array into a string. For this you can use implode

file_put_contents($file, implode("\n", $matches[1]));

Wildteen your awesome!! helped me with alot of stuff today..

 

one more question

 

so

file_put_contents($file, implode("\n", "blah".$matches[1]));

writes the matches each on a new line... how would I go about putting something in front of the id like this

 

$ID[] = 1234578;
$ID[] = 1234578;
$ID[] = 1234578;
$ID[] = 1234578;
$ID[] = 1234578;
$ID[] = 1234578;

 

instead of

1234578
1234578
1234578
1234578
1234578

 

Thanks!

If you're planning on adding all ids into an array again then you can just open the file with file. That function will load each line into an array. So you won't need to add $ID[] = at the start of each line.

sweet that works! now one last thing and ill be done..

 

how would I add a \n line break at the beginning of each id

[devWhiz]

Cant edit above post, but this is the code I have..

 

<?php
$file = 'Lastfm IDs.txt';
$ch = curl_init();
for($cwb=1; $cwb!=399; $cwb++)
{
curl_setopt($ch, CURLOPT_URL, "http://www.last.fm/group/i'm+not+anti-social%2C+i+just+enjoy+my+music./members?memberspage=".$cwb);	
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
preg_match_all('/id="r4_([\d]+)">/', curl_exec($ch), $matches);
file_put_contents($file, implode($matches[1], "\n"), FILE_APPEND);
echo "#".$cwb." pages with user ids loaded...\n";
}
curl_close($ch);
sleep(100000);
?>

 

now,, everytime it does a loop it loads a different members page.., every time it loads a new one and writes the ids from that page.. it looks like this in the id file

 

14423441
32839962
36683385
3670648838089858
11899884
31379239
31517343
14856674

 

when it should be

 

 

14423441
32839962
36683385
36706488
38089858
11899884
31379239
31517343
14856674

 

Thanks for the help man

Change to use this line, it'll add the extra return.

 

file_put_contents($file, implode($matches[1], "\n")."\n", FILE_APPEND);

 

May I ask in what way these id's will be used? I'm curious.

[devWhiz]

shit man so simple! how did I not think of that.. prob cuz I tried it without implode and it just wrote "Array" to the file Lol, thanks man I appreciate it!!

 

And last.fm is a site where people can discover new music based on the music you scrobble on yor computer with the last fm scrobbler, so it records everything you listen to and recommend similar artists to broaden your taste and such in music.. if that makes sense

 

well this script loads members pages from group on the site that people put together so people can talk about music and such, well the script loads all of the ids of members in the group.. and writes to a text file..

 

Later on I am going to make a script that will request friendship with that list of ids.. I will have a couple hundred thousand by time Im done

 

Thanks for the help, Im sure I will need some help when I go to write the script to add the friends, I usually get stuck where it is always a simple solution.. Lol
