PHP Remove section of array before a certain key value

I have an array that is in a certain order and I want to just cutoff a portion of the array starting from the first index to the index of a given key.

IE... If i had this array

$array = array("0" => 'blue', "1" => 'red', "2" => 'green', "3" => 'red', "4"=>"purple");

I want to cut off the first part of the array before the key "2" (as a string) is seen. So the end array would be something like...

"2" => 'green'

"3" => 'red'

"4"=>'purple'

Thanks, Ian开发者_运维技巧

For your case you can use

print_r(array_slice($array, 2, count($array),true));

EDIT: For edited question

$cloneArray = $array;
foreach($array as $key => $value){
  if($key == $givenInex)
     break;

  unset($cloneArray[$key]);
} 

Then use $cloneArray

$newarray = array_slice($array,2,-1,true);

Yes u have to use array_slice() function in php for ur solution..............

example code is below,

`
$input = array("a", "b", "c", "d", "e");

$output = array_slice($input, 2);      // returns "c", "d", and "e"
$output = array_slice($input, -2, 1);  // returns "d"
$output = array_slice($input, 0, 3);   // returns "a", "b", and "c"

// note the differences in the array keys
print_r(array_slice($input, 2, -1));
print_r(array_slice($input, 2, -1, true));

`

the above code give u the following output,

Array ( [0] => c [1] => d ) Array ( [2] => c [3] => d )
