[RESOLVED] concatenate variables

bumbar

Hallo!

I have this script. And I want concatenate three variables:

<?php
$begin = "begin";
$end = "the end";
$arr = array ("a", "b", "c");

function listarray () {
	global $arr;
   foreach ($arr as $values) {

  echo $values;

   }
}

$concat  = $begin . listarray () . $end;

echo $concat;
?>

But result crashed down :rolleyes: .

Any suggestions ?

There are a few ways to do this. The easiest is probably [man]implode[/man]. But if you want a function to do it I think that the following would work:

<?php
$begin = "begin";
$end = "the end";
$arr = array ("a", "b", "c");

function listarray ($arr) { // Include the array instead of make it global. If you make it global you lose the reason to have a function.
   $concat = ""; // Set an empty variable
   foreach ($arr as $values) {

  $concat .= $value; // Adds the value to the variable $concat

   }
   return $concat;
}

$concat  = $begin . listarray($arr) . $end;

echo $concat;
?>

thank you for quick replay!

but not work correctly ...

when I test script output seems like this "begin the end".
Lost array output

Where is the BUG?

The typo where $values is used in one place and $value in the other (turn error reporting to E_ALL and you'll get a pile of complaints about that).
