Question

我有一个类似

的数组

Array ( [0] => xyz [1] => 93049 [2] => London [3] => Telephone: 45687654 [4] => Telefax: 54478453248 [5] => [6] => )

现在我想在键位[1]中添加一个空白值，并将数组的其余部分移到右侧，如

Array ( [0] => xyz [1] => [2] => 93049 [3] => London [4] => Telephone: 45687654 [5] => Telefax: 54478453248 [6] => [7] => )

我怎么能用PHP做到这一点。请建议。

Answer 1

$original = array( '0', '2', '3', '4', '5' );
$inserted = array( '1' ); 
array_splice( $original, 1, 0, $inserted );

Answer 2

array_splice()功能将解决您的目的。

试试这个：

$original = array(
    'xyz', 93049, 'London', 'Telephone: 45687654', 'Telefax: 54478453248', '', '' 
);
echo '<pre>';
print_r($original);

原始阵列：

   Array
(
[0] => xyz
[1] => 93049
[2] => London
[3] => Telephone: 45687654
[4] => Telefax: 54478453248
[5] => 
[6] => 
)

$pos = 1;       // Position where you want to insert
$string = '';   // The string you want to insert
array_splice($original, $pos, 0, '');

print_r($original);

最终输出：

  Array
(
[0] => xyz
[1] => 
[2] => 93049
[3] => London
[4] => Telephone: 45687654
[5] => Telefax: 54478453248
[6] => 
[7] => 
)

Answer 3

array_splice可以完成这项工作：

<?php
$arr = Array( "xyz","93049","London","Telephone: 45687654","Telefax: 54478453248","","" );
$new = Array( "" );
array_splice( $arr,1,0,$new ); // INSERT THE $NEW ARRAY IN POSITION 1.
var_dump( $arr );
?>

结果如下：

array (size=8)
  0 => string 'xyz' (length=3)
  1 => string '' (length=0)
  2 => string '93049' (length=5)
  3 => string 'London' (length=6)
  4 => string 'Telephone: 45687654' (length=19)
  5 => string 'Telefax: 54478453248' (length=20)
  6 => string '' (length=0)
  7 => string '' (length=0)

或者：

Array ( [0] => xyz [1] => [2] => 93049 [3] => London [4] => Telephone: 45687654 [5] => Telefax: 54478453248 [6] => [7] => )

Answer 4

您可以将任意识别的值设为黑色空间......

例如，我，任意考虑当出现“BLANK”这个词时，它是一片空白......所以：

数组（[0] =＆gt; xyz [1] =＆gt; BLANK [2] =＆gt; 93049 [3] =＆gt;伦敦[4] =＆gt;电话：45687654 [5] =＆gt;传真： 54478453248 [6] =＆gt; [7] =＆gt; .........

这不是一个明确的方法来解决它，但如果你不是寻找最干净的方式，它就会解决。

将数组的值添加到特定的键位置，并将数组的其余部分移到右侧
