带有一个头文件的不同页面标题？

Question

How do you do multiple page titles with on header file? Theres one thing though. For the index page, i've got

error_reporting(0);
if ($_GET["error"]=="404") { 
    include("forum/styles/art_air/web_template/overall_header.php");
    include("include/404"); 
    include("include/index");
    include("forum/styles/art_air/web_template/overall_footer.php");
} else { 
    include("forum/styles/art_air/web_template/overall_header.php");
    include("include/index");
    include("forum/styles/art_air/web_template/overall_footer.php");
}

So i would have the header before anything else. So how would i manage to make so that

index?error=404 and index have different titles? Thanks in advance.

Use JavaScript and document.title.

Example:

<script language="javascript">document.title = "My Title"</script>

JS can be used in body.

Another method is to set a $GLOBAL variable before including everything.

Example:

error_reporting(0);
$GLOBALS['404'] = 0;
if ($_GET["error"]=="404") { 
    $GLOBALS['404'] = 1;
    include("forum/styles/art_air/web_template/overall_header.php");
    include("include/404"); 
    include("include/index");
    include("forum/styles/art_air/web_template/overall_footer.php");
} else { 
    $GLOBALS['404'] = 0;
    include("forum/styles/art_air/web_template/overall_header.php");
    include("include/index");
    include("forum/styles/art_air/web_template/overall_footer.php");
}

In your overall_header.php:

if($GLOBALS['404'] == 1) echo '<title>404: Not Found</title>';
else echo '<title>My Title</title>';
