如何定义数组元素的顺序?

php

Array
        (
            [1] => a
            [2] => b
            [3] => c
            [4] => d
            [5] => e
            [6] => f
            [7] => g
            [8] => h
            [9] => i
            [11] => j
            [13] => k
            [14] => l
            [15] => m
            [16] => n
            [17] => o
            [18] => p
            [19] => q
            [20] => r
            [21] => s
            [22] => t
            [23] => u
            [24] => v
            [25] => w
        )

是否有一个函数,使我的数组的范围从1到23?所以看起来像这样?

            [3] => c
            [4] => d
            [5] => e
            [6] => f
            [7] => g
            [8] => h
            [9] => i
            [10] => j
            [11] => k
            [12] => l
            [13] => m
            [14] => n
            [15] => o
            [16] => p
            [17] => q
            [18] => r
            [19] => s
            [20] => t
            [21] => u
            [22] => v
            [23] => w
        )

如果需要零索引数组:

$new = array_values($array);

如果您想从一个aribitrary数字开始(在本例中:1);

$new = array_combine(range(1,count($array)),array_values($array));

那怎么办 range() ?

$array = range('a', 'w');

更新: 哦,你不是来自 1 到 23 . 干得好:

$array = array_combine(range(1,23), range('a', 'w'));

此代码段将执行以下操作:

$new = Array();
$i = 1;
foreach ($original as $element) {
    $new[$i] = $element;
    $i++;
}

jkilbride 15 年前

$newArray = array_values($array);

$startAtIndex1Array = array();
//shift indexes to start at 1
foreach($newArray as $key=>$value) {
    $startAtIndex1Array[$key+1] = $value;
}

$tmpArray = Array
        (
            [1] => a
            [2] => b
            [3] => c
            [4] => d
            [5] => e
            [6] => f
            [7] => g
            [8] => h
            [9] => i
            [11] => j
            [13] => k
            [14] => l
            [15] => m
            [16] => n
            [17] => o
            [18] => p
            [19] => q
            [20] => r
            [21] => s
            [22] => t
            [23] => u
            [24] => v
            [25] => w
        );

foreach($tmpArray as $v){
  $tmpArray2[count($tmpArray2)] = $v;
}

它可以做你想做的,但是你应该考虑用一个key=0来启动你的数组
