Move all array elements into one variable

[tripodkid]

Hello!

I have writtern a script that captures keywords from a large multidimensional array using a for loop.

<?
if ($iptc_type == "2:25")	{
$keywords[] = $iptc_data[$i]['RecData'];
}

I can then echo all the keywords using another for loop.

<?
sort ($keywords);
for ($i = 0; $i<count($keywords); $i++){
$keywords[$i]; . ";" . " ";
echo $keywords;
}
?>

It would be really useful to move the contents of $keywords[] in to a formated variable, so then I just echo the varible, but I've not been able to figure it out! I'm sure it's really easy!

As always, any help would be appreciated! Thanks!

This would be it then:

$one_per_line = implode("<br>", $keywords);
echo $one_per_line;

Just change the "<br>" to whatever you which to have between the keywords.

You could also do this with a while loop:

$i=0;
while ($i<count($keywords)){
echo $keywords[$i]."<br>";
$i++;
}
