It is necessary to remove part of the array. Here is an example of an array:
Array ( [0] => one [1] => two [2] => three [3] => four [4] => five )
The variable can be based on one of the following values in the array. Suggests there is 'three'. Need to take one, two and everything else removed.
Is there any standard methods, or a good solution that would not need to use a loop?
You can use array_splice for that
$input = array("red", "green", "blue", "yellow");
array_splice($input, 1, -1);
// $input is now array("red", "yellow")
If you don't want to use a loop, you could use array_splice.
$input = array("red", "green", "blue", "yellow");
array_splice($input, $varaible, -1);
// $input is now array("red", "yellow")
This will use @JeroenMoons array_splice but will do the array_search I suggested too
function reduce_my_array($array, $value)
{
// look for location of $value in $array
$offset=array_search($value, $array);
// if not found return original
if($offset===false) return $array;
// remove from the found offset to the end of the array
return array_splice($array, $offset+1);
}
Note:
array_search returns the INDEX which can be 0
array_splice uses number of entries as the offset
so for your example with numerical indexes 0 to ... you need to tell array splice index+1
