Question

I have a variable that looks like this:

$var = "Dropdown\n
  Value 1\n
  Value 2\n
  Value 3\n";

As you can see it’s basically values broken by line breaks.

What I want to do is get the Option Type, in this case “Dropdown” and store the rest of the values in another string.

So

list($OptionType, $OptionValues) = explode("\n", $var);

The code above is what I tried but this is what the strings came out as:

$OptionType = 'Dropdown'; //Good
$OptionValues = 'Value 1';  // Only got the first value

I want $OptionValues to be like this:
$OptionValues = “Value 1\nValue 2\nValue 3\n”;

How would I do something like that?

The Option Type is always going to be the first part of the string followed by option values each seperated by a linebreak.

It’s organized this way as it comes from user-input and it makes it much easier on the user to handle.

Answer 1

You need to use the third argument of explode(), which sets the limit.

$var = "Dropdown\n
  Value 1\n
  Value 2\n
  Value 3\n";

list( $foo, $bar ) = explode( "\n", $var, 2 );

echo $bar;
