help with foreach loop results

[CyberShot]

I am using a foreach loop to get the results of an array. My problem is that I need the results combined into one string. How can I accomplish this?

One of a billion ways. Can you be more specific? Maybe even post code?

If i got it right ... you wana do something like this?

 

foreach ($array[key] as $key => $value){
$string .= $value.", ";
}
$string = substr($string, 0, -2); // Delete the last 2 characters
echo $string;

 

I would require more of your code in order to show you exacly how it's done but the above is an exemple.

foreach($options['exc_cat'] as $cat) {
echo $cat;
}

 

this code returns 1 5

 

I want it to display as 1,5

 

I have been searching and tried substr($cat, 0, -1) but this strips all the commas from the string. the way I am returning the value, it prints as 1,5, I need the last comma after the 5 to go away. But the substr strips all commas which just donned on me that the foreach loop loops through, returns 1, then loops again and returns 5, I want to combine the total overall results into one string so that I can strip the trailing comma.

close, that gave me 551 instead of 5,1

do it like this

foreach($options['exc_cat'] as $cat) {
if ($cat!=""){$string .= $cat.",";}
}
$string = substr($string, 0, -1); // Delete the last character
echo $string;

Absolutely perfect my friend! That was an even better solution than I was hoping for. It worked perfect! I had to use the results in a wordpress query and getting the results out of the foreach loop made it great.

 

Thank you.
