[Resolved] [Resolved] Array Implode And...

SP8600

If i use:

$arrayFiles = implode( "\n", $fileTypes );

To input the array with the file types allowed to be uploaded into a textarea (one per line) so that they can be edited what is the command to change it back to:

'gif','jpg'

Back into an array, or into a string formatted in that method?
Back into an array: implode should do that...
Into a string: explode(",",$array)

Ok i got that now, but how can i echo an array in its full with all the seperators?

You want to make a variable (or just echo) with every key separated by a comma?
Simple, just use:
echo(explode(",",$array));

SP8600

But echo(explode(",",$array)); just brings back "Array"

Whoops, implode().. I'm sorry. 😛

They're backwards in my mind... (And in logic... you figure you'd explode an array into a bunch of keys, and implode a bunch of keys into an array!)

Ok, thanks i got the idea now but still when the array is saved to the vars.php file, theres a new line for each array entry which i can't have. Heres the snips of code i am using:

To input the array into the textarea with an array enty one per line:
$arrayFiles = implode("\n", $fileTypes );

To get the contents of the textarea and get it ready to go back into the array:
$arrayFiles = explode("\n", $_POST["fileTypes"]);
$fileArrayAdd = (implode("','",$arrayFiles));

And the way i write to the file:
$write .= "\$fileTypes = array('$fileArrayAdd');";

So how can i get ride of that line break in the array?

Hi,

To remove all line breaks from the following:

$fileArrayAdd = (implode("','",$arrayFiles));

You can just do this:

$fileArrayAdd = str_replace("\n","",$fileArrayAdd);

You can combine that function into the implode line if you require.

Cheers,
