Question

I’m using PHP’s foreach(), Sometimes when the inner code doesn’t do what i want, I’d like to re-try the same level instead of continuing to the next one.

Is that possible?

Example:

foreach($pics AS $pic){
  if(!upload($pic)){
    again; // something like this
  }
}

No but you can put a while loop inside your loop, this has equivalent behaviour as what you desire above. However you should modify it to use a counter and stop after X many retries to prevent infinite looping.

foreach($pics AS $pic){
  while(!upload($pic));
}
