Interweaving 2 arrays into a string. Please help.

[bluegray]

Hi Php freaks,

 

So I'm pulling an array from a $_POST, and in it I have its keys and values.

 

Take this example:

 

"1" => "a"
"2" => "b"
"3" => "c"

 

Now, if I can separate the keys and the values into their own arrays, what I need to do is interweave them into a string where all keys are matched up to their values like such:

 

<string> 
1 = "a", 2 = "b", 3 = "c" 
</string>

 

I'm trying to build a function that does, this and here's what it looks like so far:

 

if(!isset($data)) {
    $boxdata = array();
} else {
	$boxdata = isset($data)?$data:null ;
	//var_dump($boxdata) ;

	foreach ($boxdata as $bd) {
		$keys = array_keys($boxdata);
		} 

 

I figured it would be simplest to build the string from the foreach () loop, but don't know how to do it, or if there are better ways. 

 

Ideas please?

Well, there are actually many different ways you could do this, as you can imagine.

 

I don't see why you don't do something like this:

 

	

echo "<string>";
foreach ($boxdata as $bkey => $bdatum) {
echo "$bkey = $bdatum<br />";
}
echo "</string>"; 

 

this way you don't actually have to deal with two arrays. you can get the key right from the foreach loop

Try this:

<?php
$test = array('first','second','third');
$tmp = array();
foreach ($test as $k => $v) {
  $tmp[] = $k . ' = ' . $v;
}
echo implode(', ',$tmp);
?>
