Multiple reg.exp. and a loop

look_at_me

Hi!
I've worked out this code to grab stuff from a gallery website...
<?php
$content = strip_tags(implode("",file('http://ADDRESS/')),'<a><img>');
preg_match_all("/<a.?href=\"(.+?)\".?>(.+?)<\/a>/is",$content,$matches);

for ($i=0;$i<count($matches[0]);$i++) {
$txt = $matches[2][$i];
echo 'URL : '.$matches[1][$i].' ';
echo 'Text : '. $txt .' ';
preg_match("/(\d+) pics made by (.+)$/i",$txt,$out);
echo 'Pics : '. $out[1] .' ';
echo 'Author : '. $out[2] .' ';
}
?>

But the out array doesn't contain anything, nothing is written after "pics" and "author"...
Can you please tell me what i'm doing wrong?

Does the "Text:" part print out what it's supposed to? I'm guessing not...

This doesn't look right:

for ($i=0;$i<count($matches[0]);$i++) {
$txt = $matches[2][$i];
echo 'URL : '.$matches[1][$i].' ';

I think it should be this instead:

for ($i=0;$i<count($matches);$i++) {
$txt = $matches[$i][2];
echo 'URL : '.$matches[$i][1].' ';

look_at_me

Yes, the "TEXT:" AND THE "URL:" part print out, its just the two other parts that doesn't. 😕

mrhappiness

what's the content of $txt?

look_at_me

(num) pics made by (alpha)

where num is numbers and alpha is alpha characters

look_at_me

swr > I tried correcting it, but then it didn't print out anything. So that part of the code should be right.

mrhappiness

you have those brackets in your text, e. g. $txt may be b pics made by (look_at_me)[/b]?

if yes then try %((.)) pics made by ((.))%siU as pattern

look_at_me

No, without the brackets, like "45 picx made by look_at_me"

mrhappiness

echo '-'.$txt.'-';

and look at the generated html source

do you have any spaces or newlines between - and the content of $txt?

look_at_me

But there's something that i don't understand. When i run the following code in an individual document, it runs fine, but when it runs in a loop it don't:

$txt = "45 pics made by look_at_me";
preg_match("/(\d+) pics made by (.+)$/i",$txt,$out);
echo 'Pics : '. $out[1] .' ';
echo 'Author : '. $out[2] .' ';

mrhappiness

see my post above

look_at_me

Yeah, i have a white space infront of the number and a whitespace behind the name of the author

mrhappiness

$txt = trim($txt);

do that before your preg_match

look_at_me

yeah, i thought that it might work too, but it didn't 🙁

look_at_me

it's just wierd that it works when i run it alone, and don't run it in a loop.

mrhappiness

it's really whitespace?

would you mind posting the adress of interest or pm it to me?

look_at_me

No it's not whitespace now when i've used trim(), but it had a few before i did, but still doesn't work...

mrhappiness

and now the html source says -45 pics made by look_at_me-?

look_at_me

exactly...

mrhappiness

would you mind showing me your code including the trim and the echo used for debuging?

what if you remove the $ from your pattern?
