如果变量名称已开始添加，我要显示所有发布变量-
例如：这是带有后置变量的完整字符串：
Array ( [PartNumber] => sfd [Description] => dsf [Issue] => dfs [Customer] => J.C.B. SERVICE [widget7-table_length] => 5 [add_332/F2684] => [add_333/D1641] => sdf [add_333/D1202] => [add_332/F3144] => sdf [add_332/F3147] => sfd [makeassy] => )
我只想在数组中显示
[add_332/F2684] => [add_333/D1641] => sdf [add_333/D1202] => [add_332/F3144] => sdf [add_332/F3147] => sfd
我正在尝试
print_r($_POST['add_%']);
但是，您如何看待这篇文章，它不起作用。你有什么想法吗？
使用array_filter提取特定的数组键：
$output = array_filter($_POST,function($e) {
return strpos($e,'add_') === 0;
},ARRAY_FILTER_USE_KEY);
您可以尝试使用preg_grep()
$res= preg_grep ('/^add_ (\w+)/i',$_POST);
var_dump($res);
使用Foreach的另一种解决方案
<?php
$x = array(
'PartNumber' => 'sfd','Description' => 'dsf','add_332/F2684' =>'asd','add_333/D1641' =>'sdf','add_333/D1202' => 'asd','TESTEST' => 'ASDASD' );
$tmp = array();
foreach($x as $key => $value)
{
if(substr( $key,3 ) === "add")
{
array_push($tmp,array($key =>$value));
}
}
die(print_r($tmp));
?>
输出：
Array
(
[0] => Array
(
[add_332/F2684] => asd
)
[1] => Array
(
[add_333/D1641] => sdf
)
[2] => Array
(
[add_333/D1202] => asd
)
)
