以数字方式重新索引数组

Question

How can i remove NULL values in an array with its index and reassign the index to other values in order?

Array
(
    [1] => 115,2010-02-17,19:30
    [3] => 400,2006-03-01,22:00
    [4] => 474,2006-04-10,02:30
    [5] => 7547,2006-08-02,23:16
)

But what i need is:

Array
(
    [1] => 115,2010-02-17,19:30
    [2] => 400,2006-03-01,22:00
    [3] => 474,2006-04-10,02:30
    [4] => 7547,2006-08-02,23:16
)

Answer 1

try like this

<?php
$array=array(0=>"a",3=>"b");
$b=array_values($array);
print_r($b);
//displays Array ( [0] => a [1] => b ) 
?>
