regex and metacharacters help please

[juschillinnow]

my string to search is:

[sound-file]
this is the sound file

[file-header]
This is the file header

I need to grab the headers such as sound-file and file-header. But since they are inside the [] the ereg is giving me some problems here's what I got

ereg("^{\[[a-z]*\]$",} $contents, $match);

But that is not working.

[juschillinnow]

I changed it to this:

ereg("[[a-z]*]", $contents, $match);
echo $match[0];
foreach($match as $v){ echo $v."<br>"; }

But it only returns the first occurance of the match. Any suggestions here?

Here's all my code

$filename = "/etc/asterisk/ivr.conf";
$file = fopen($filename, "r");
$contents = fread($file, filesize($filename));
fclose($file);
//echo $contents;
ereg("\[[a-z]*\]", $contents, $match);
foreach($match as $v){ echo $v."<br>"; }

Here's a snippet of file to be searched

exten => 1,1,VoiceMail(291)
exten => 2,1,VoiceMail(292)
exten => 3,1,VoiceMail(293)

[earlylate]
exten => s,1,Wait(1)
exten => s,2,Answer
exten => s,3,Wait(1)
exten => s,4,Background(atcom-greeting)
exten => s,5,Background(atcom-night-ts)
exten => s,6,Playback(ts-intrude)
exten => s,7,Queue(tech|t)
exten => i,1,Queue(tech|t)

[failsafe]
exten => s,1,Wait(1)
exten => s,2,Answer
exten => s,3,Wait(1)
exten => s,4,Background(atcom-greeting)
exten => s,5,Background(atcom-night-ts)
exten => s,6,Queue(tech|t)
exten => i,1,Queue(tech|t)

Try preg_match_all instead

preg_match_all("/\[([\w]+)[^\]]*\](.*)/", $contents, $match);
print_r($match);

[juschillinnow]

ok, that seems to work. Not exactly but almost. When I echo out in a loop it give me two sets of matches, one with brackets, one without

That's probably because of how I'm echoing.

Is there a way to do this with eregi or ereg though?

[juschillinnow]

it seems that eregi only returns the first match. How can I get it to go through the whole string and pull out matches?

[LordShryku]

Only by splitting it up into an array and looping.

$array = explode("\n", $string);
foreach($array as $a) {
   if(eregi("\[([a-z]+)\]", $a, $match)) {
      echo "Matched: ".$match[1]."\n";
   }
}

That would work, but if you're going to go that route, you might as well use [man]file[/man] to open the file, instead of exploding it. That's why preg_match_all was made, just doesn't seem to be an equivalent in ereg.
