only making it try to include if the file is there to include

[Borked]

I'm building a webpage that uses includes in conjunction with $PHP_SELF to supply the content. I've hit a snag though, because I'm trying to figure out a way to make it try to include a file if and only if the file exists. Here's what I'm trying to do. the top part is the interesting part.

<?php
$directory=opendir(./);

$file = (readdir($directory);

/*I need a way to say that when one of the entries in the array $file matches one of the entries from a list I provide below, do the rest of the script, otherwise, do nothing.  */


while (array('writing.php','projects.php','other.php','credo.php','biography.php','scratchpaper.php','nonsense.php','otheropinions.php','news.php')





if (isset($_GET['includewriting'])) 
{ 
$includewriting=$_GET['includewriting']; 

if ($includewriting=='writing.php') 
	{include 'writing.php'; }

if ($includewriting=='projects.php')
	{include 'projects.php';}

if ($includewriting=='other.php')
	{include 'other.php';}

	if ($includewriting=='credo.php')
	{include 'credo.php';}

	if ($includewriting=='biography.php')
	{include 'biography.php';}

		if ($includewriting=='scratchpaper.php')
	{include 'scratchpaper.php';}

		if ($includewriting=='nonsense.php')
	{include 'nonsense.php';}

		if ($includewriting=='otheropinions.php')
	{include 'otheropinions.php';}

if ($includewriting=='news.php')
	{include 'news.php';}
}  


  ?>

a simpiler way of doing this is just include all the possible files, but used '@' to silent them so that the script just keeps going if they are not there, like this:

@include('writing.php');
@include('projects.php');
@include('other.php');
// etc....

or, if you want to track which files did and did not include, but don't want to stop the script, do something like this:

if (!@include('writing.php')) {
  // if the file does not "include", a notice is added to an error variable
  //which can be examined later to track which pages were included:
  $error_msgs[] = "writing.php was not included";
}

if (!@include('projects.php')) {
  $error_msg[] = "projects.php was not included";
}

// etc...

if (isset($_REQUEST['section'])=='admin') { 
   $path = "admin/";
   $page = $_GET['page'];
   $page .= ".php";
   $path .= $page;
   if (file_exists("$path")) { 
     include $path; 
   } else { 
   echo "This file does not exist";
   }
} elseif (isset($_REQUEST['page'])) { 
   $page = $_GET['page'];
   $page .= ".php";
   if (file_exists("$page")) { 
     include $page; 
   } else { 
   echo "This file does not exist";
   }
} else { 
   include 'news.php';
}

thanks all, all three posts were useful. Where can I read about the symbols '@' and '!' ?

Generally about operators:

Specifically about @:
