Using Explode

[Sabaote]

Hi, i need, save 3 $vars in a bd .txt ..

but, i can't.. i use the function explode..
ex.:

$var1 = "Test";
$var2 = "test";
$var3 = "test";
$save = explode("|", $var1,$var2,$var3);
but, this write in Database,
Array

and not the $vars... separated for |
help-me please..
Sorry my bad english.. i'm from brazil.. 🙂
Thanks.

explode takes an array (a multi-valued variable) and splits it, by a character or string..

what you are doing here is putting 3 single vars to explode..

secondly there is no "|" in your variables var1 var2 or var3, so how can it explode what's on each side of the | if there aren't any?

finally you can't say echo or print a string that's an $array (and all variables to the left of the = of an explode expression are arrays) so you'd have to say echo $save[0], $save[1], $save[2]

this is how explode works....

$var='text1|text2|text3';

$save = explode("|", $var1);

what you get is:

$save[0] = text1;
$save[1] = text2;
$save[2] = text3;

I hope that helps, but I'm pretty sure I'd have to come to Brazil and show you in person if I'm going to explain it any better

The function that you are looking for is implode.

use it like this:
$new_value = implode("|","text1","text2","text3");

then write $new_value to your text file.

minor correction, implode must not have more than 2 arguments.

but this should work:
$new_value = implode("|", array($var1, $var2, $var3));
