Start foreach with a certain array

[paulson]

Hi

I can't find a way of starting the foreach loop from a certain array, I have an array with 1000 values, and I want to start the loop with the 500th value, skipping the first 500, is this possible?

For an array with numeric indices:

foreach($array as $key => $value) {
   if($key < 500) { continue; }
   //regular foreach code goes here
} 

For an array where you want to start at a certain value:

$startLoop = false;
$startValue = "value of array you want to start at";
foreach($array as $key => $value) {
  if($value == $startValue) { $startLoop = true; }
  if(!$startLoop) { continue; }
   //regular foreach code goes here
} 

An alternative to both methods is to use a for loop...might be a little better because you don't have to run through the first 500 continue statements, but it may also not be because you'll have to use some other functions.

For a numeric indexed array:

for($i=500;$i<=sizeof($array);$i++) {
   //do something with the array values - $arr_value = $array[$i];
}

foreach(array_slice($array, 500, -1, true) as $key => $value) {
    echo "$key: $value\n";
} 

You can skip the 3rd and 4th parameters for array_slice if you dont care about the keys.
