==Behavior of Files Included Using include==



<source lang="html4strict">

//File: test.inc
<?php
echo "Inside the included file<BR>";
return "Returned String";
echo "After the return inside the include<BR>";
?>
<?php
echo "Inside of includetest.php<BR>";
$ret = include ("test.inc");
echo "Done including test.inc<BR>";
echo "Value returned was "$ret"";
?>

</source>

==Including files relative to the current file==



<source lang="html4strict">

<?php
$currentDir = dirname(__FILE__);
include $currentDir . "/functions.php";
include $currentDir . "/classes.php";
?>

</source>

==Including Other Files==



<source lang="html4strict">

//foo.php:
<?php
print "Starting foo\n";
include "bar.php";
print "Finishing foo\n";
?>

//bar.php:
<?php
print "In bar\n";
?>

After including foo.php would look like this:
<?php
print "Starting foo\n";
print "In bar\n";
print "Finishing foo\n";
?>

</source>

==Using include() to Execute PHP and Assign the Return Value==



<source lang="html4strict">

<html>
<head>
<title>Acquiring a Return Value with include()</title>
</head>
<body>
<div>
<?php
$addResult = include("another.php");
print "The include file returned $addResult";
?>
</div>
</body>
</html>

//An Include File That Returns a Value
//another.php
<?php
$retval = ( 4 + 4 );
return $retval;
?>

</source>

==Using include to Load Files in PHP==



<source lang="html4strict">

//File: library.inc
<?
function is_leapyear($year = 2004) {
$is_leap = (!($year % 4) && (($year % 100) || !($year % 400)));
return $is_leap;
}
?>
<?php
include ("library.inc"); // Parentheses are optional
$leap = is_leapyear(2003);
?>

</source>

==Using include() Within a Loop==



<source lang="html4strict">

<html>
<head>
<title>Using include() Within a Loop</title>
</head>
<body>
<div>
<?php
for ( $x=1; $x<=3; $x++ ) {
$incfile = "incfile".$x.".txt";
print "<p>";
print "Attempting include $incfile<br/>";
include( "$incfile" );
print "</p>";
}
?>
</div>
</body>
</html>

</source>
