PHP：从服务器传递数组到客户端不工作！

问题描述：

The server Contents are server.php:

<?php 
$err["foo"]="bar";
?>

The client.php

<?php
require 'server.php';
echo "<p> Server says: $err['foo']</p>";
?>

But,This code works : The new server Contents are server.php:

<?php 
$err["foo"]="bar";
$errAssign=$err["foo"];
?>

The client.php

<?php
require 'server.php';
echo "<p> Server says: $errAssign</p>";
?>

Why am i not able to get the contents of the array from the server ?

Tried the following in the client.php

 echo "<p> Server says: $err[\'foo\']</p>";
 echo "<p> Server says: $err[\"foo\"]</p>";
 echo "<p> Server says: $err[foo]</p>";

None of which are working!!.. please help !!

服务器内容为server.php： p>

 ＆lt;  ？php 
 $ err [“foo”] =“bar”; 
？＆gt; 
  code>  pre> 
 
  client.php  p> 
 
  
 ＆lt;？php 
require'server.php'; 
echo“＆lt; p＆gt;服务器说：$ err ['foo']＆lt; / p＆gt;”; 
？＆gt; 
   pre> 
 
 但是，此代码有效：
新服务器内容为server.php： p> 
 
 
 ＆lt;？php 
  $ err [“foo”] =“bar”; 
 $ errAssign = $ err [“foo”]; 
？＆gt; 
  code>  pre> 
 
 客户端。  php  p> 
 
 
 ＆lt;？php 
require'server.php'; 
echo“＆lt; p＆gt;服务器说：$ errAssign＆lt; / p＆gt;”; 
？＆gt;  
  code>  pre> 
 
 为什么我无法从服务器获取数组的内容？ p> 
 
 
在客户端中尝试以下操作 .php  p> 
 
 
  echo“＆lt; p＆gt;服务器说：$ err [\'foo \']＆lt; / p＆gt;”; 
 echo“＆lt; p＆gt;服务器 说：$ err [\“foo \”]＆lt; / p＆gt;“; 
 echo”＆lt; p＆gt;服务器说：$ err [foo]＆lt; / p＆gt;“; 
  code>  pre  > 
 
 这些都不起作用!!请帮助!!  p> 
  div  >

答

You need to use braces for array and object access in ":

echo "<p> Server says: {$err['foo']}</p>";

Or if it were an object property/method:

echo "<p> Server says: {$err->foo}, {$err->getFoo()}</p>";

答

In client.php you must do:

<?php
require 'server.php';
echo "<p> Server says:" . $err['foo'] . "</p>";
?>

Much better, it must work. Note the "." symbol separator to use with strings.

答

You could simply say:

echo "<p> Server says: ".$err['foo']."</p>";
