Need Serialize Example

edpudol

I read from PHP manual and some forums the serialize can be use for cross url variable references.

The problem is I can't find a simple script that I can use as my reference, Could you please give me a simple code how to do use the serialize function in cross url.

Another... question does var_export can be use for to call or transfer the value of variable in cross url. Means from other site to second site.

Thanks

Serialized data can be sent intra-site using, e.g., post, get (if it's not over c. 2 k😎, or sessions. An example with sessions:

$test_array = array('a' => 1, 'b' => 2, 'c' => 3);
$serial = serialize($test_array);
$_SESSION['ser'] = $serial;

Then, on another page, it could be accessed like this:

$unser_arr = unserialize($_SESSION['ser']);
foreach ($unser_arr as $key => $value) {
    echo $key . ' => ' . $value . '<br />';
}

To send it across domains, you could post it:

$test_array = array('a' => 1, 'b' => 2, 'c' => 3);
$serial = serialize($test_array);
echo '<form action="http://example.com/script.php" method="post">';
echo '<input type="hidden" name="ser" value="' . $serial . '" />';
echo '<input type="submit" name="submit" value="send" />';
echo '</form>';

Then access it like this:

$unser_arr = unserialize($_POST['ser']);
foreach ($unser_arr as $key => $value) {
    echo $key . ' => ' . $value . '<br />';
}

As for "var_export()", you can use it to write a variable to a file, then, from another site, include that file into a script. From the first site:

$test_array = array('a' => 1, 'b' => 2, 'c' => 3);
$export_var = var_export($test_array, true);
echo $export_var;
$fp = fopen('export_test.inc', 'w');
fwrite($fp, "<?php\n" . '$test_array = ' . $export_var . ";\n?>");
fclose($fp);

(Having those PHP open and close tags in the "fwrite()" statement screws up the colorizing, and the escape slashes for newline don't show. Don't forget them.)

Then, on the second site, include it into a script:

include('http://example.com/export_test.inc');
foreach ($test_array as $key => $value) {
    echo $key . ' => ' . $value . '<br />';
}

When including cross-site, make sure the file extension is one that won't cause the foreign server to interpret the file as php, otherwise you'll get the output, not the raw file.
