PHP 배열 입문 튜토리얼 - 배열 채우기

本文介绍下，有关php数组之数组填充的一个例子，有需要的朋友参考下。

在php编程中，对数组元素进行填充，可以使用array_fill()函数。

来看下面的例子，array_fill()函数——填充数组函数：

<?PHP
//数组填充 
//array_fill()例子
//by bbs.it-home.org
$array = range(1,10);
$fillarray = range("a","d");
$arrayFilled = array_fill(0,5,$fillarray);//$fillarray可以是字符串，如"test".
echo "<pre class="brush:php;toolbar:false">";
print_r ($arrayFilled);
echo "

"; $keys = array("string","2",9,"SDK","PK"); $array2 = array_fill_keys($keys,"testing"); echo "

";
print_r ($array2);
echo "

"; ?>

运行结果：

Array ( [0] => Array ( [0] => a [1] => b [2] => c [3] => d )

[1] => Array ( [0] => a [1] => b [2] => c [3] => d )

[2] => Array ( [0] => a [1] => b [2] => c [3] => d )

[3] => Array ( [0] => a [1] => b [2] => c [3] => d )

[4] => Array ( [0] => a [1] => b [2] => c [3] => d )

) Array ( [string] => testing [2] => testing [9] => testing [SDK] => testing [PK] => testing )
