How can I remove an element of an array, and reorder afterwards, without having an empty element in the array?
<?php
$c = array( 0=>12,1=>32 );
unset($c[0]); // will distort the array.
?>
Answer / Solution: array array_values ( array $input ).
<?php
$c = array( 0=>12,1=>32 );
unset($c[0]);
print_r(array_values($c));
// will print: the array cleared
?>
will return a new array with just the values, indexed linearly.
