如何删除阵列和在PHP

Question

创造了新的阵列，这是我的数组：

array(10) { 
    [0]=> string(29) "Cass Luxury Shapewear Bottoms" 
    [1]=> string(8) "xBhjsN9G" 
    [2]=> string(2) "20" 
    [3]=> string(57) "Cass Luxury Shapewear Bottoms. Multiple Styles Available." 
    [4]=> string(29) "cass-luxury-shapewear-bottoms" 
    [5]=> string(28) "Curabitur non nulla sit amet" 
    [6]=> string(8) "vjIhw8cw" 
    [7]=> string(3) "500" 
    [8]=> string(690) "posuere cubilia Curae; Donec velit neque." 
    [9]=> string(28) "curabitur-non-nulla-sit-amet" 
} 

删除此阵：

[5]=> string(28) "Curabitur non nulla sit amet" 
[6]=> string(8) "vjIhw8cw" 
[7]=> string(3) "500" 
[8]=> string(690) "posuere cubilia Curae; Donec velit neque." 
[9]=> string(28) "curabitur-non-nulla-sit-amet" 

Answer 1

使用unset()取消设置一个这样的数组：

unset($array[5]); //if the index is 5 

举例：

<?php 

    $array = array(
       array(1), 
       array(2) 
      ); 

    echo "<pre>"; 
    print_r($array); 

    unset($array[1]); 

    echo "<pre>"; 
    print_r($array); 

?> 

输出：

Array 
(
    [0] => Array 
     (
      [0] => 1 
     ) 

    [1] => Array 
     (
      [0] => 2 
     ) 

) 


Array 
(
    [0] => Array 
     (
      [0] => 1 
     ) 

) 

Answer 2

我们需要循环并通过其索引中删除。

// $items is your array variable 

for ($i = 0; $i < count($items); $i++) { 

    if ($i >= 5 && $i <= 9) { 
     unset($items[$i]); 
    } 
} 

print_r($items); 

希望它可以帮助
