将PHP阵列清​​理为一个

Question

array(1) {
  [0] => string(18) "AnotherTestSnippet"
}
array(1) {
  [0] => string(17) "Test Code Snippet"
}
array(1) {
  [0] => string(18) "AnotherTestSnippet"
}
array(1) {
  [0] => string(17) "Test Code Snippet"
}

如何使用PHP将上面的数组转换为这种格式？

array("AnotherTestSnippet","Test Code Snippet")

那就是清理并删除重复项.我尝试过array_unique和in_array,但它不起作用.谢谢.

Answer 1

Let's call your arrays $array1 through $array4. Here is the solution:

$cleanArray = array_unique(array_merge($array1, $array2, $array3, $array4));

EDIT:

Now that I know you are starting with a single, multi-dimensional array, this is not the correct answer. The correct answer is the for loop given by Dainis Abols.

Answer 2

只需执行一个循环并仅保存您的唯一条目：

<?php
$array = array (
    array( "AnotherTestSnippet" ),
    array( "Test Code Snippet" ),
    array( "AnotherTestSnippet" ),
    array( "Test Code Snippet" )
);

$new_array = array();

foreach ( $array as $value )
{
    if( !in_array( $value[0], $new_array) ) $new_array[] = $value[0];
}

输出：

Array
(
    [0] => AnotherTestSnippet
    [1] => Test Code Snippet
)
