[RESOLVED] Preg_Match

UKlee

Hi Happy New Year to you all

Ok here is my problem I hope someone can help me with this.

I am opening a .txt file using

<?php 
$filename = "some.txt";

$fd = fopen ($filename, "r");
$contents = fread ($fd,filesize ($filename));
fclose ($fd);

$delimiter = "\n";
$splitcontents = explode($delimiter, $contents);



foreach( $splitcontents as $record )
	{

preg_match("/(.*)/", $record, $info); 

echo '<b><pre>', print_r($info, TRUE), '</b></pre>';

}

?>

my file has sections with lines of information and they go a little like this

RNWS
RNW 05L
RNW 05R
RNW 23L
RNW 23R
ENDRNWS

What I would like to do is get the information between RNWS and ENDRNWS and insert that into an array so all the lines bellow RNWS until I reach ENDRNWS array for each line.

How would I be able to do this any ideas.

thanks in advance and all the best for 2009

I would suggest something along these lines:

$contents = file_get_contents($filename);

$info = array();
if (preg_match('/RNWS\n(.*)\nENDRNWS/s', $contents, $matches)) {
    $info = explode("\n", $matches[1]);
}

The [man]file_get_contents/man call replaces your calls to fopen(), fread(), etc.

one option

$want_it=0;
foreach( $splitcontents as $record ){ 
if ($record =='RNWS'){
$want_it=1;
}

if($want_it){
$new_array[]=$record;
}

if ($record =='ENDRNWS'){
$want_it=0;
}
}

laserlight's is much better

Your suggestion is still workable though, though I would modify it to:

$contents = file($filename);

$info = array();
$has_started = false;
foreach ($contents as $line) {
    $line = rtrim($line);
    if ($line == 'ENDRNWS') {
        break;
    } else if ($has_started) {
        $info[] = $line;
    } else if ($line == 'RNWS') {
        $has_started = true;
    }
}

since my impression is that there will not be multiple RNWS/ENDRNWS pairs.
