make an array into a variable?

How can I separate all the contents of an array by a "," and then make that string a variable?

 

Is this what you were looking for?

thanks, i will look it over.

but to clear it up. I have:

say "blue" "green" "orange" in an array

I want: $variable to equal blue, green, orange

 

Yeah, that's pretty much what the function does.

 

for some reason it won't work.
i echoed the new varialbe. and it just displays: Array

 

use the following code:

$string="";
$i=0;
while($array[$i]!="") {
$string .= $array[$i];
$i++;
}

 

Are you sure you're echoing the new variable instead of the array? The function outputs a string, not an array.

 

foreach($array as $v)
{
   $string .= $v . ",";
}

PHP:

that'll do it ..... $string now contains array1,array2,array2

 

No point is iterating through it, just use implode() like you suggested earlier..

<?php

	$colorArray = array("blue", "green", "red");
	$colors = implode(",", $colorArray);
	
	// Outputs: blue,green,red
	echo $colors;

?>

PHP:

 

he said that didn't work for him already, so I thought Id present another way....

 

I've used the same function for the same purpose over and over. The only reason it wouldn't work would be an easy to fix oversight.

 

thanks all...
for some reason, I had saved it the correct way, then ctrl+z (accident) and i guess saved it again.
so it didn't work.
