This example demonstrates the process of implementing inclued into an existing application, and viewing the results.
Example #1 Getting the data within the PHP application itself (function)
<?php
// File to store the inclued information
$fp = fopen('/tmp/wp.ser', 'w');
if ($fp) {
$clue = inclued_get_data();
if ($clue) {
fwrite($fp, serialize($clue));
}
fclose($fp);
}
?>
Now that some data exists, it's time to make sense of it in the form of a graph. The inclued extension includes a PHP file named gengraph.php that creates a dot file that requires the » graphviz library. However, this form is not required.
Example #2 Example use of gengraph.php
This example creates an image named inclued.png that shows the inclued data.
# First, create the dot file $ php gengraph.php -i /tmp/wp.ser -o wp.dot # Next, create the image $ dot -Tpng -o inclued.png wp.dot
Example #3 Listing data via inclued dumps (configuration)
When using the inclued.dumpdir directive, files (include clues) are dumped with every request. Here's one way to list those files, and unserialize() them.
<?php
$path = ini_get('inclued.dumpdir');
if ($path && is_dir($path)) {
echo "Path: $path", PHP_EOL;
$inclues = new GlobIterator($path . DIRECTORY_SEPARATOR . 'inclued*');
if ($inclues->count() === 0) {
echo 'No clues today', PHP_EOL;
exit;
}
foreach ($inclues as $inclue) {
echo 'Inclued file: ', $inclue->getFilename(), PHP_EOL;
$data = file_get_contents($inclue->getPathname());
if ($data) {
$inc = unserialize($data);
echo ' -- filename: ', $inc['request']['SCRIPT_FILENAME'], PHP_EOL;
echo ' -- number of includes: ', count($inc['includes']), PHP_EOL;
}
echo PHP_EOL;
}
} else {
echo 'I am totally clueless today.', PHP_EOL;
}
?>
以上例程的输出类似于：
PATH: /tmp/inclued Inclued file: inclued.56521.1 -- filename: /Users/philip/test.php -- number of includes: 1 Inclued file: inclued.56563.1 -- filename: /tmp/none.php -- number of includes: 0 Inclued file: inclued.56636.1 -- filename: /tmp/three.php -- number of includes: 3
