看来我的表述很模糊:
下边我详细说一下:
我想在A页面的HTTP HEADER中加入一个自己定义的字段。比如叫personalChar,值为1然后我用B页面去请求A页面,我希望在B 页面中得到A页面的头信息。当然其中必须包含我在A页面中所定义的那个personalChar字段和它的值。请问:如何解决?

Description
array get_meta_tags ( string filename [, int use_include_path])
Opens filename and parses it line by line for <meta> tags in the file. This can be a local file or an URL. The parsing stops at </head>. Setting use_include_path to 1 will result in PHP trying to open the file along the standard include path as per the include_path directive. This is used for local files, not URLs.
Example 1. What get_meta_tags() parses<meta name="author" content="name">
<meta name="keywords" content="php documentation">
<meta name="DESCRIPTION" content="a php manual">
<meta name="geo.position" content="49.33;-86.59">
</head> <!-- parsing stops here -->
(pay attention to line endings - PHP uses a native function to parse the input, so a Mac file won't work on Unix). The value of the name property becomes the key, the value of the content property becomes the value of the returned array, so you can easily use standard array functions to traverse it or access single values. Special characters in the value of the name property are substituted with '_', the rest is converted to lower case. If two meta tags have the same name, only the last one is returned. Example 2. What get_meta_tags() returns<?php
// Assuming the above tags are at www.example.com
$tags = get_meta_tags('http://www.example.com/');// Notice how the keys are all lowercase now, and
// how . was replaced by _ in the key.
print $tags['author']; // name
print $tags['keywords']; // php documentation
print $tags['description']; // a php manual
print $tags['geo_position']; // 49.33;-86.59
?>
然后B中如下引用
<?php
echo $personalChar
?>
