Array and recursion

[anulaibar]

I am trying to create a function that returns the contents of an array as a string. It should accept arrays of any dimension. It is not working very well, but I got this far:

function show($variable, $buffer){

  if (is_array($variable)){
	  foreach($variable as $key => $value){
		  $buffer = $buffer.$key."<br>";
		  return show($value, $buffer);
	  }
  }

  else{
	  return $buffer.$variable."<br>";
  }

}

  $fruit = array('banana', 'orange', 'pear');
  $peas = array('yellow peas', 'green peas', 'black-eyed peas');
  $berries = array('blueberries', 'strawberries', 'raspberries');

  $DArray = array('fruit' => $fruit, 'peas' => $peas, 'berries' => $berries);

  echo show($DArray, '');

Any suggestions anyone?

if you do not need any formating, you can use the print_r() function, along with the "<pre>" code in html :

<pre>
<?php
print_r($DArray);
?>
</pre>

Your recursion isnt written correctly, from what I see. You might be trying to do something along the lines of:

function show($array) {
	$ret = '';
	foreach ($array as $key => $value) {
		if (is_array($value)) {
			$ret .= $key . ":<br />\n" . show($value);
		} else {
			$ret .= $value;
		}
		$ret .= "<br />\n";
	}
	return $ret;
}

Thank you laserlight, exactly what I needed!
