[thelist] PHP regex script returns empty array

[Madhu Menon]

RIght, so I'm a PHP newbie, so maybe I'm missing something obvious here.

What I'm trying to do is extract all the 10-digit numbers beginning with 
9 from a mass of text. The regex I'm using seems to be OK. The problem 
is with the script that displays the results.

Here's what I'm using:



<?php

$rawtext=$_POST["JDS"];

$pattern = '/\b9[0-9]{9}/';

preg_match_all ($pattern, $rawtext, $results);

foreach ($results as $v) {
    echo $v;
}


// var_dump($results);


?>


JDS is the name of the HTML form element capturing the input text. 
$pattern is obviously the regex.

So in theory, this should display all the matches found in the text, right?

Except that it doesn't.

The only output from that script is the word "Array"

What makes it weirder is that when I used var_dump to check the contents 
of the array, it displays the matches just fine. Here is a sample output:

array(1) { [0]=> array(36) { [0]=> string(10) "9845439405" [1]=> 
string(10) "9880000211" [2]=> string(10) "9972584305" [3]=> string(10) 
"9845347327" [4]=> string(10) "9886742603" [5]=> string(10) "9739044591" 
[6]=> string(10) "9986018897" [7]=> string(10) "9900596375" [8]=> 
string(10) "9972008039" [9]=> string(10) "9741199007" [10]=> string(10) 
"9845075685" [11]=> string(10) "9886730267" [12]=> string(10) 
"9844234519" [13]=> string(10) "9916045790" [14]=> string(10) 
"9980139070" [15]=> string(10) "9739774949" [16]=> string(10) 
"9902532000" [17]=> string(10) "9980082324" [18]=> string(10) 
"9731300083" [19]=> string(10) "9886734884" [20]=> string(10) 
"9845947753" [21]=> string(10) "9880276754" [22]=> string(10) 
"9986370202" [23]=> string(10) "9845364884" [24]=> string(10) 
"9743999629" [25]=> string(10) "9886736757" [26]=> string(10) 
"9845670085" [27]=> string(10) "9980177506" [28]=> string(10) 
"9886133381" [29]=> string(10) "9886897583" [30]=> string(10) 
"9886298328" [31]=> string(10) "9886328642" [32]=> string(10) 
"9845194794" [33]=> string(10) "9845418801" [34]=> string(10) 
"9845770764" [35]=> string(10) "9845770764" } }


So what the heck is happening? What am I doing wrong?
