[Editor's Note:
It is easier to do the same thing using array_values()
]
array_slice() can be used to "re-index" an array to start from key 0. For example, unpack
creates an array with keys starting from 1;
<?php
var_dump(unpack("C*","AB"));
?>
produces
<?php
array(2) {
[1]=>
int(65)
[2]=>
int(66)
}
?>
and
<?php
var_dump(array_slice(unpack("C*","AB"),0));
?>
give you
<?php
array(2) {
[0]=>
int(65)
[1]=>
int(66)
}
?>
