Question

I know how to do this… I’ll give example code below. But I can’t shake the feeling that there’s a clever way to accomplish what I want to do without using a variable like $isfirstloop.

$isfirstloop = true;
foreach($arrayname as $value) {
 if ($isfirstloop) {
  dosomethingspecial();
  $isfirstloop = false;
 }
 dosomething();
}

Is there any way to execute dosomethingspecial() only on the first loop, while executing dosomething() on every loop, without introducing a variable like $isfirstloop?

Thanks!

foreach ($arr as $i => $val)
{
  if ($i == 0) { doSomethingSpecial(); } // Only happens once.
  doSomething(); // Happens every time.
}
