Question

I have following records in text file, need to extract that record form text file and treat them as seperate array variables

r1=(1,2,3)|r2=(4,5,6)|r3=(1,2,3,4,5,7)|rn=(9,6,7,8) seperated by pipe(|)

I need to represent that as array use seperately like below

$r1= Array
(
[0] => 1
[1] => 2
[2] => 3
)

$r2=Array
(
[0] => 4
[1] => 5
[2] => 6
)

I have no idea how to do it, is it possible in php?

Answer 1

You can use Eval

//Assuming  you can pull the content from text file using fread

$temp = "r1=(1,2,3)|r2=(4,5,6)";
$temp=str_replace("=","=array",$temp);
$split=explode("|",$temp);
echo "<pre>";
foreach($split as $k=>$v){
      $v="$".$v.";";
      //Evaluate a string as PHP code .i.e You will get r1,r2 as a variable now which is array
      eval($v);
}

print_r($r1);
print_r($r2);
