Hi all
I recently needed seek functionality in arrays, and couldn't find it in the
regular set of array functions, so I wrote a function for it. (Seek = getting
an array value based on the position (or offset, if you want to call it like
that), and not the key of the item)
Basically you can use it like this:
$input = array(3, 'bar', 'baz');
echo array_seek($input, 2); // returns 'baz'
echo array_seek($input, 0); // returns 3
echo array_seek($input, 5); // returns NULL, emits an out of range warning
I was wondering if it's useful to add this to the family of array functions. I
know there is a somewhat similar thing in SPL (ArrayIterator::seek), but that
doesn't work exactly like what I was aiming for.
Attached is a patch for the function against the 5.3 branch. If approved, I
could add it to svn + testcases + docs. Feedback please :-)
Kind regards,
Felix
Hello Felix !
Why not use arrayIterator::seek() ?
Best regards,
Fred
