How to limit recursive function in php?

@filiberto 

You can limit a recursive function in PHP by introducing a condition that checks the recursion depth or the number of times the function has been called. Here is an example:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
15
16
17

function myRecursiveFunction($param, $depth = 0) {
  // Check if the recursion depth has reached the limit
  if ($depth >= 10) {
    return; // exit the function to limit recursion
  }
  
  // Perform recursive operations
  
  // Increment the depth counter
  $depth++;
  
  // Call the function recursively
  myRecursiveFunction($newParam, $depth);
}

// Calling the recursive function
myRecursiveFunction($param);

In the above example, the myRecursiveFunction takes an additional parameter $depth that keeps track of the recursion depth. Each time the function calls itself recursively, the $depth is incremented.

The condition if ($depth >= 10) checks if the recursion depth has reached the desired limit (in this case, 10). If the limit is reached, the function simply returns without further recursive calls, thus limiting the recursion.

You can adjust the limit by changing the value in the condition to suit your needs.

Note that it's important to have a condition in your recursive function that will eventually terminate the recursion, even if the limit is not reached. Without it, the function will keep calling itself indefinitely, resulting in a stack overflow error.
