I have a problem in calling an anonymous method in another anonymous method.
<?php
$x = function($a)
{
return $a;
};
$y = function()
{
$b = $x("hello world a");
echo $b;
};
$y();
?>
Error:
Notice: Undefined variable: x in C:\xampp\htdocs\tsta.php on line 7
Fatal error: Function name must be a string in C:\xampp\htdocs\tsta.php on line 7
Add use to your $y function, then scope of $y function will see $x variable:
$y = function() use ($x){
$b = $x("hello world a");
echo $b;
};
