HI,
I'm generating a random 4 digit code and trying to get some 'Play' statements in between the letters. I'm thinking the code below explains my attempt better. Its wrong, just not sure why its failing.


//get random 4 digit approval id
$approval_id = rand(1001,9998);

//lets assume the random number was 2345
//here I'm not sure if you can explode a string without some kind of separator?

$breakit = explode("", $newapproval_id);

//trying to get new variable to be: <Play>audio/2.wav</Play><Play>audio/3.wav</Play>... and so on

$approval = "<Play>audio/<?php echo $breakit[0]?>.wav</Play><Play>audio/<?php echo $breakit[1]?>.wav</Play><Play>audio/<?php echo $breakit[2]?>.wav</Play><Play>audio/<?php echo $breakit[3]?>.wav</Play>";
?>

You could use str_split http://php.net/manual/en/function.str-split.php

Here's an example:

$breakit = str_split($newapproval_id);

//trying to get new variable to be: <Play>audio/2.wav</Play><Play>audio/3.wav</Play>... and so on

foreach ($breakit as $a)
{

    $approval .= '<Play>audio/'.$a.'.wav</Play>';

}

echo $approval;

<?php

//get random 4 digit approval id
$approval_id = rand(1001,9998);

// Generate string
$approval = "";
for($i = 0; $i < strlen($approval_id); $i++)
{
  $approval .= "<Play>audio/".substr($approval_id,$i,1) . ".wav</Play>";
}

?>

Thank you. I used the second one but the first one looked equally promising.
