将数组推入第一个索引变得复杂 - complicate array push to the first index

complicate array push to the first index

我创建了一个多维数组就像

$column = array( 
"person#1"=> array ("name"=>"Leon" , "Age"=>"19" ),
"person#2"=> array ("name"=>"Gary" , "Age"=>"31" ),
"person#3"=> array ("name"=>"May" , "Age"=>"25" )
)

现在，我想要推送一些像

这样的东西

"person#4"=> array ("name"=>"Tony" , "Age"=>"28" )

移到数组列的第一个位置。

I had look into

array_unshift($column, array("person#1"=> array ("name"=>"Tony" , "Age"=>"28" ));

它确实用我的数组替换了数组和变量，但总是以'0'索引，而不是期望的person#4

为什么不做一个简单的$new_person + $column呢?

使用array_merge():

<?php
header('Content-Type: text/plain');
$column = array(
"person#1"=> array ("name"=>"Leon" , "Age"=>"19" ),
"person#2"=> array ("name"=>"Gary" , "Age"=>"31" ),
"person#3"=> array ("name"=>"May" , "Age"=>"25" )
);
$column = array_merge(array( "person#4" => array ("name" => "Tony" , "Age" => "28" )), $column);
var_dump($column);
?>

节目:

array(4) {
  ["person#4"]=>
  array(2) {
    ["name"]=>
    string(4) "Tony"
    ["Age"]=>
    string(2) "28"
  }
  ["person#1"]=>
  array(2) {
    ["name"]=>
    string(4) "Leon"
    ["Age"]=>
    string(2) "19"
  }
  ["person#2"]=>
  array(2) {
    ["name"]=>
    string(4) "Gary"
    ["Age"]=>
    string(2) "31"
  }
  ["person#3"]=>
  array(2) {
    ["name"]=>
    string(3) "May"
    ["Age"]=>
    string(2) "25"
  }
}
