Array to string

jc94062

Is there any way to grab all the values from an array and put them into one long string.

ie:

You have an array called $pointless containing The, Man, Walks, The Dog, now if I do
$output = "$pointless[0]$pointless[1]$pointless[2]$pointless[3]$pointless[4]";
echo "Output: $output";

I get The Man Walks The Dog.

Is there a way to do this without the long and tedious way, ie, if I don't know the number of items in the array...
I've tried for/while loops and looking over the manual, I was hopeful that settype might work, but while it changed the type (according to gettype) it still just said array if I tried to echo the "string".

Thanks for any help!

First, determine the numer of items in the array:

$num = count($pointless);

Then loop through the array and add to the $output variable:

for ($i=0; $i<$num; $i++) {
$output .= "$pointless[$i]";
}

echo "Output: $output";

That should do it.

WHAT?????????????

implode(), implode()

http://www.php.net/implode

$output = implode(\' \', $pointless);

Of course remember to remove the stupid backslashes this forum sticks in there.

Hmmm, thats what I tried, without the dot (typo?)

Anyway, I'll give it a go, maybe it doesn't like my dodgy home PHP installation.

you could also try using array_values()....

Anon

Ah!

Yep, that dot IS needed!

Thanks, works great!

.= is a variable assignment shortcut. This: $x .= $y basically reads $x equals $x with $y appended to $x.

Ah okay.
I've used it before for things like $var1.$var2 and stuff, but never seen it in that context.
