Php 将键和值对推入多维数组

请注意，这不是重复，而是以下问题的延伸）

我试图将数组_推入多维数组，但希望保留第二个数组的数组键

例如：

<?php
$samplearray = array(
array('name' => "Joe Bloggs", 'age' => "30", 'sex' => "Male", 'title' => "Mr" ),
array('name' => "Jane Bloggs", 'age' => "30", 'sex' => "Female", 'title' => "Mrs" ),
array('name' => "Little Bloggs", 'age' => "10", 'sex' => "Male", 'title' => "Master" ),    
);

array_push ($samplearray[0],"Inserted Value");

print_r($samplearray);
?>

在本地服务器上为插入的密钥返回空值，但在PHPfiddle上失败。

这就是您要查找的吗

        $samplearray = array(
        array('name' => "Joe Bloggs", 'age' => "30", 'sex' => "Male", 'title' => "Mr" ),
        array('name' => "Jane Bloggs", 'age' => "30", 'sex' => "Female", 'title' => "Mrs" ),
        array('name' => "Little Bloggs", 'age' => "10", 'sex' => "Male", 'title' => "Master" ),
    );

    $samplearray[0]['othername'] = 'lalala';
    echo '<pre>';
    print_r($samplearray);

    )

$samplearray[0]['insertedvalue'] = "Inserted Value";
