[英]How to compare two array value and get matched inner array value in PHP
如何比较两个数组值并从内部数组中删除重复值并使用 PHP 存储在另一个数组中。 由 array[name] 比较的数组,并希望删除所有内部数组中的相关索引。
阵列 1
Array
(
[0] => detail12.docx
[1] => resume.docx
)
阵列 2
Array
(
[name] => Array
(
[0] => detail12.docx
[1] => document.pdf
[2] => resume.docx
)
[type] => Array
(
[0] => application/vnd.openxmlformats-officedocument.wordprocessingml.document
[1] => application/pdf
[2] => application/vnd.openxmlformats-officedocument.wordprocessingml.document
)
[tmp_name] => Array
(
[0] => /tmp/php2LK7xC
[1] => /tmp/phpTEWqXG
[2] => /tmp/phpAKki0M
)
[error] => Array
(
[0] => 0
[1] => 0
[2] => 0
)
[size] => Array
(
[0] => 30887
[1] => 86118
[2] => 30887
)
)
预期 Output:-
Array
(
[name] => Array
(
[0] => detail12.docx
[1] => resume.docx
)
[type] => Array
(
[0] => application/vnd.openxmlformats-officedocument.wordprocessingml.document
[1] => application/vnd.openxmlformats-officedocument.wordprocessingml.document
)
[tmp_name] => Array
(
[0] => /tmp/php2LK7xC
[1] => /tmp/phpAKki0M
)
[error] => Array
(
[0] => 0
[1] => 0
)
[size] => Array
(
[0] => 30887
[1] => 30887
)
)
我需要 output,如上面预期的 Output 所示。 请提供代码以获得解决方案!
这个方法用array_search
保存name
中找不到的key,以后用foreach
删除
$a = ['detail12.docx', 'resume.docx'];
$b = [
'name' => ['detail12.docx', 'document.pdf', 'resume.docx', 'test.php'],
'type' => ['application/vnd.openxmlformats-officedocument.wordprocessingml.document', 'application/pdf', 'application/vnd.openxmlformats-officedocument.wordprocessingml.document', 'test']
];
$keys = [];
foreach($b['name'] as $index => $value){
if(array_search($value, $a) === false){
$keys[] = $index;
}
}
foreach($b as $index => $array){
foreach($keys as $key){
unset($b[$index][$key]);
}
}
print_r($b);
Output:
Array
(
[name] => Array
(
[0] => detail12.docx
[2] => resume.docx
)
[type] => Array
(
[0] => application/vnd.openxmlformats-officedocument.wordprocessingml.document
[2] => application/vnd.openxmlformats-officedocument.wordprocessingml.document
)
)
附言。 当然,我创建了一个包含一些条目的示例,作为视觉测试
