count in function recursion

[MDanz]

function width2($noid)
	{
		$getwidth =  mysql_query("SELECT * FROM block WHERE sid='$theid'",$this->connect);

			while($row1 = mysql_fetch_assoc($getwidth)) {

			$this->width2($noid);


			}

	}

 

how do i count how many times the function loops?

You can use a static variable.  Static variables retain their values each time you call a function.  It's sort of like a global variable but within the function's scope.  (You can of course also just use a global variable, but this keeps it with the function scope).

 

Normal:

function blah () {
  $x++;
  echo $x;
}

for ($y = 0;$y<10;$y++) {
  blah();
}

// output: 1111111111

 

Static

function blah () {
  static $x;
  $x++;
  echo $x;
}

for ($y = 0;$y<10;$y++) {
  blah();
}

// output: 12345678910
