[SOLVED] Remove

[Bakes]

I'm really confused with my REGEX's. They work horribly, so I'm not even going to post them here.

 

000001 "Go Away" (W) GUID=671e78a6308032bed8b1d14587e24de4(VALID) [2009.05.28 19:22:06]

How would I strip all the characters other than:

671e78a6308032bed8b1d14587e24de4

 

Please help, I've been stuck with this for hours!

Something like this?

 

$str = '000001 "Go Away" (W) GUID=671e78a6308032bed8b1d14587e24de4(VALID) [2009.05.28 19:22:06]';
preg_match('#GUID=([^(]+)#', $str, $match);
echo $match[1];

 

Granted, this doesn't strip out the characters, but rather fetches just what you are looking for. If you need to strip them out, you can do something like this instead:

 

$str = preg_replace('#^.+?GUID=([^(]+).*#', '$1', $str);

 

This assumes of course that the string is on a line all by itself.

I'm trying to use this to get 00001 (It's a url, actual code is):

<a href="pb000001.htm" target="_blank">000001</a> "Go Away" (W) GUID=671e78a6308032bed8b1d14587e24de4(VALID) [2009.05.28 19:22:06]

This is what I'm using, it works in testers, yet doesn't in my code. Can you tell what the problem is?

preg_match('#<a href="([^"]+)#', $lines[$i], $id);

I'm confused. First you state you want to value of GUID (more or less), and now you want the value of href? You're not being clear on what exactly you are trying to shoot for.

 

If you are looking for pb000001.htm in you string (in other words, the value of your href), add the closing quote after the capture:

 

preg_match('#<a href="([^"]+)"#', $lines[$i], $id); // note the closing "

 

You'll want to echo / use $id[1] for this captured value.

I want them both (in seperate values)

 

Unfortunately, that doesn't work (returns a blank page).

I want them both (in seperate values)

 

Why didn't you say so in your initial post? Would make things a little easier, no?

 

So is this something along the lines of what you are looking for?

$str = '<a href="pb000001.htm" target="_blank">000001</a> "Go Away" (W) GUID=671e78a6308032bed8b1d14587e24de4(VALID) [2009.05.28 19:22:06]';
preg_match('#<a href="([^"]+)".+?GUID=([^(]+)#', $str, $id);
echo $id[1] . ' - ' . $id[2];

 

 

If there is going to be multiple examples of this anchor tag in the string you are searching, you can use preg_match_all instead:

 

$str = '<a href="pb000001.htm" target="_blank">000001</a> "Go Away" (W) GUID=671e78a6308032bed8b1d14587e24de4(VALID) [2009.05.28 19:22:06]
<a href="pb000002.htm" target="_blank">000001</a> "Go Away" (W) GUID=431e78a6308032bed7b1d16679e24de5(VALID) [2009.05.28 19:22:06]';

preg_match_all('#<a href="([^"]+)".+?GUID=([^(]+)#', $str, $id);
$count = count($id[0]);
for ($a = 0 ; $a < $count ; $a++) {
echo $id[1][$a] . ' ' . $id[2][$a] . "<br />\n";
}

Unfortunately, it's still a blank page. My code is:

 

<?php

$str = implode('', file('pbsvss.htm'));

preg_match_all('#<a href="([^"]+)".+?GUID=([^(]+)#', $str, $id);
$count = count($id[0]);
for ($a = 0 ; $a < $count ; $a++) {



echo $id[1][$a] . ' ' . $id[2][$a] . "<br />\n";
}
?>

What is the value of $str if you echo it out after imploding? Troublehsooting variables by examining their contents will help out. You can use print_r or var_dump to check out what the variables in question hold.

okay first off, instead of this:

 

$str = implode('', file('pbsvss.htm'));

 

do this:

 

$str = file_get_contents('pbsvss.htm');

 

And then in your regex, do this:

 

preg_match_all('#<a href="([^"]+)".+?GUID=([^(]+)#is', $str, $id);

 

if that doesn't fix it, post some actual content of pbsvss.htm

[Bakes]

<?php

$str = file_get_contents('pbsvss.htm');

preg_match_all('#<a href="([^"]+)".+?GUID=([^(]+)#is', $str, $id);

$count = count($id[0]);
for ($a = 0 ; $a < $count ; $a++) {



echo $id[1][$a] . ' ' . $id[2][$a] . "<br />\n";
}
?>

okay so the previous content you showed had quotes around the href value.  This content you are showing right now does not. I sure hope there isn't any more "confusion" about what you're *really* after...

 

preg_match_all('~href=([^\s]*).+?GUID=([^(]*)~is',$string,$matches);
echo "<pre>"; print_r($matches);

[nrg_alpha]

Ah, I missed that he was trying to implode a file...
