重置PHP数组索引

我有一个PHP数组，看起来像这样：

[3] => Hello [7] => Moo [45] => America 

什么PHPfunction使这个？

 [0] => Hello [1] => Moo [2] => America 

Answer 1

array_values()函数^{[ 文档 ]}做到这一点：

 $a = array( 3 => "Hello", 7 => "Moo", 45 => "America" ); $b = array_values($a); print_r($b); 

 Array ( [0] => Hello [1] => Moo [2] => America )
