I have this array similar to this:

$suppliers = array(
  'Utility Warehouse' => array('Gas' => array(0,0), 'Electricty' => array(0,0)),
  'British Gas' => array('Gas' => array(93,124), 'Electricty' => array(93,124)),
  'Eon' => array('Gas' => array(93,124), 'Electricty' => array(93,124))
);

How can display the information as follows

Utility Warehouse
Gas: 0-0 Electricity 0-0

British Gas
Gas: 93-134 Electricity: 93-134

Eon
Gas: 93-124 Electricity: 93-134

You can see how the displayed data corresponds to the data in the array. I've tried this:

foreach($suppliers as $a){
    echo $a[0];
}

But this does nothing. CONFUSED!

UPDATE Need to say thanks guys, and I apologise for my lack of knowledge. I have never used nested arrays before, and I did search around for a solution before I posted here.

What information about PHP arrays or foreach loops made you expect that that code was going to produce those results? I'm confused as to how you imagined that the code you have would output results formatted with newlines, colons, and hyphens. – sequoia mcdowell Oct 18 '11 at 14:24
    
I wasn't expecting all the colons, newlines etc.... that was an example of what I was hoping would output the suppliers name for example – Lee Price Oct 18 '11 at 14:39

Oh, I see what you mean. Well, for future reference, the echo language construct only takes strings as an argument, tho it will attempt to convert things (integers, etc.) to strings. Arrays don't have an automatic method to convert to strings so you can't echo an whole array. Check out the examples here. – sequoia mcdowell Oct 18 '11 at 14:47

<?php 

foreach($suppliers as $supplier => $category) {
    echo $supplier . '<br />';
    foreach($category as $cat_name => $values_arr) {
        echo $cat_name . ': ' . implode('-', $values_arr) . '<br /><br />';
    }
}

?>

+1 for implode. – sequoia mcdowell Oct 18 '11 at 15:58

you can try:

foreach($suppliers as $name => $value) {
    echo $name . "<br />";
    foreach($value as $a => $price) {
        echo $a .': '. $price[0].'-'.$price[1];
    }
    echo "<br /><br />";
}

The code to achieve what you want would be following, but i suggest you brush up on your PHP skills a bit more, as this is a trivial task.

foreach($suppliers as $name => $data){
    echo $name . '<br/>';
    foreach($data as $utility => $value){
        echo $utility . ': ' . $value[0] . '-' . $value[1] . ' ';
    }
    echo '<br/><br/>';
}

Same answer as everyone else (I'm too slow). Here's a working example: http://codepad.org/PDPEjAGJ

Also, everyone who answered this question, me included, is guilty of spoonfeeding. Ahh well, the things I'll do for points! :p
