php读取其他php文件

Question

I have one php page (index.php) with following contents:

<php
    include("{$_SERVER['DOCUMENT_ROOT']}/somefunction.php")
    echo "hello world";
?>

Now I want to read the contents of index.php via another php-file (test.php) The result I want to get is:

line 1: include("{$_SERVER['DOCUMENT_ROOT']}/somefunction.php")
line 2: echo "hello world";

This is what I already tried, but it won't work:

$phppage="{$_SERVER['DOCUMENT_ROOT']}/index.php";
$handle = fopen($phppage, "r");
if ($handle) {
    while (($line = fgets($handle)) !== false) {
        // process the line read.
        echo $line;
    }
    fclose($handle);
}
else {
    // error opening the file.
    echo "An error occured";
}

It just echoes an empty string.

Problem solved :-)

Actually your code is working. The problem is it will not displayed on browser . Since it contain html special character like <

So either print The result with in a <pre> </pre> tag.

or use htmlentities()

echo htmlentities($line);

or remove <?php ?> from the file index.php
