Is there any way to use a variable of a method, after a recursive call (without sending that as a parameter).
For example:
class Doc {
public function readDoc($file, $recursion = false) {
if ($recursion != false) {
// DO SOMETHING;
}
$filename = $file."Some added text";
$this->readDoc($filename, 1);
}
}
Here, is it possible to use the value of $file sent in the first call (when the readDoc() function is called recursively).
You can create a simple stack with an array, e.g.
class Doc {
private $stack = [];
public function readDoc($file, $recursion=false) {
if($recursion != false)
DO SOMETHING
$this->stack[] = $file;
$filename = $file."Some added text";
$this->readDoc($filename, 1);
}
}
And then get the first index of the array as your $file variable.
you could also use an anonymous function to work in a different scope something like this:
public function test($file, $recursion = false)
{
$rec = function($r) use ($file, &$rec)
{
if($r !== false) {
}
$filename = $file.'test';
return $rec($r);
};
return $rec($recursion);
}
in this case the $file variable always stays the same (be aware that the above example creates an infinite-loop)
