php - how to get all variable values in separate variables [closed]

Question

how to get all possible variable values in separate variables..... separated with commas

$bin="1,2,3,4,5,6,ABC,AAA,77,00,11,AS,Code";

how to get all possible variables something like this.

$NN01="1";
$NN02="2";
$NN03="3";
$NN04="4";
$NN05="5";
$NN06="6";
$NN07="ABC";
$NN07="AAA";
$NN08="77";
$NN09="00";
$NN10="11";
$NN11="AS";
$NN12="Code";

above sting can be separated with any operator other than comma thanks for your help....

What determines the name of the end variable? Should it simply be $NNxx? What if there are more than 100 variables... $NNxxx? — Chris Baker

Creating such repetitive variables is silly. Use an array. Be a better PHP Developer. — Jason McCreary

While you guys are probably right to question the application here, I don't think that it is impossible the OP has their reasons for wanting to do this. Suggest a better route, sure, but do so with the understanding that you are guessing the use case, and might be completely wrong in your assumption. — Chris Baker

You won't be able to do that, but you can explode them to an array.

$bin="1,2,3,4,5,6,ABC,AAA,77,00,11,AS,Code";
// any delimiter in place of ','
$arr = explode(',',$bin);
echo $arr[0];

Edit: Okay, it's possible. I wrongly stated that you won't be able to do that.

Downvoter want to explain themselves?

Well, you could be able to do it using eval()... but your solution is of course much better. (I'm not the downvoter)

+1 using an array is the way to go.

@LonelyWebCrawler One could, but one shouldn't.

In all fairness, this answer doesn't address the question as asked, and it wrongly states that the OP "won't be able to do this", implying that it cannot be done. It can. Downvote-worthy, probably not, but this isn't an answer to the question as asked, strictly speaking.

$bin = "1,2,3,4,5,6,ABC,AAA,77,00,11,AS,Code";
list ($NN01,$NN02,$NN03,$NN04,$NN05,$NN06,$NN07,$NN07,$NN08,$NN09,$NN10,$NN11,$NN12) = $bin;

or for something completely dynamic

$i = 0;
foreach ($bin as $val) {
    $temp = 'NN' . str_pad(++$i, 2, '0');
    $$temp = $val;
}

You can use the explode function to turn the initial value into an array:

$bin="1,2,3,4,5,6,ABC,AAA,77,00,11,AS,Code";
$array_of_values = explode(',' $bin);

That will give you a numerically indexed array, which looks like this:

Array
(
    [0] => 1
    [1] => 2
    [2] => 3
    [3] => 4
    [4] => 5
    [5] => 6
    [6] => ABC
    [7] => AAA
    [8] => 77
    [9] => 00
    [10] => 11
    [11] => AS
    [12] => Code
)

You can just use that and access individual values by their index:

echo $array_of_values[0]; // 1

See more about arrays: http://php.net/manual/en/language.types.array.php

From there, if you want to set the values into variables, you can use this loop, which uses "variable variables":

$bin= "1,2,3,4,5,6,ABC,AAA,77,00,11,AS,Code";
$array_of_values = explode(',', $bin);
$vn = 'NN';
foreach ($array_of_values as $k=>$v) {
  ${$vn.$k} = $v;
}
echo 'NN1:'.$NN1; // NN1:2
echo 'NN2:'.$NN2; // NN2:3
echo 'NN2:'.$NN3; // NN3:4

Try it: http://codepad.org/Ee8F9F18

Another idea is to use extract, and provide a desired prefix.

$bin="1,2,3,4,5,6,ABC,AAA,77,00,11,AS,Code";

This will give you $NN_0 .. $NN_11, where 'NN' is the prefix you chose.

extract( explode( ',', $bin ), EXTR_PREFIX_ALL, 'NN' );

Nice! I had thought about this route too, but forgot about the prefix argument and didn't want to loop the array to add keys. Well played :) (OTOH, extract is very evil)

Not sure what you are trying to accomplish, but why not to use array() ?

It works simple.

$YourArray = array ( "NN01" => "1", "NN02" => "2") // And so on

He probably doesn't want to hardcode it...

Francisco Presencia Over a year ago

Wasn't sure as the real question wasn't too clear. Seeing other answers make it a lot clearer now.
