PHP self-test script -- need suggestions

A client has an account on a vendor's server.  We have no control over system updates/parameters.
About once a week something will happen that breaks some facet of PHP.
the most common is suhosin either gets protected or uninstalled.
example error:

[16-Apr-2014 09:15:01] PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/local/lib/php/extensions/no-debug-non-zts-20060613/suhosin.so' - /usr/local/lib/php/extensions/no-debug-non-zts-20060613/suhosin.so: cannot open shared object file: No such file or directory in Unknown on line 0

Please offer experience/advice/suggestions for a script  that can be run in an (hourly) cron job that checks basic PHP health (including suhosin)  and if there's a problem
emails the error to us.

thanks

Good grief!  Get a new hosting company!  That's a technically incompetent installation, and if the hosting company cannot fix it, they don't know what they are doing and that is dangerous for your work.  You probably do not want Suhosin in any case.

If you want to look for the error_log file, this script will do the job.  You may want to modify it to send an email, text or tweet.  It will scan all of the directories in the tree and show you the error_log contents.  Install it in the web root and run it from the browser to see what it creates.

<?php // find_error_log.php
error_reporting(E_ALL);
ob_start();

// PUT THIS SCRIPT IN THE WEB ROOT DIRECTORY
$path = realpath(getcwd());
$plen = strlen($path);

// THE ERROR LOG FILE NAME
$signal = strrev('error_log');


// IF THERE IS A POST-METHOD REQUEST TO DELETE THE ERROR LOG
if (!empty($_POST['log']))
{
    // MAKE SURE WE ONLY UNLINK THE ERROR LOG FILE
    $test = strrev($_POST['log']);
    if (strpos($test, $signal) === 0)
    {
        unlink($path . $_POST['log']);
        echo '<h3>' . $_POST['log'] . ' Discarded</h3>';
    }
}


// SEE http://php.net/manual/en/class.recursivedirectoryiterator.php#85805
$objs = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path), RecursiveIteratorIterator::SELF_FIRST);

// UNFORTUNATELY THIS DOES NOT WORK AT PHP 5.4
// var_dump($objs);

// ITERATE OVER THE OBJECTS
foreach($objs as $name => $obj)
{
    // PROCESS THE ERROR LOG ONLY
    $test = strrev($name);
    if (strpos($test, $signal) === 0)
    {
        $name = substr($name, $plen);
        $form = <<<EOD
<form method="post" style="margin:0; padding:0; display:inline;!important">
<b>$name</b>
<input type="submit" value="Discard?" />
<input type="hidden" name="log" value="$name" />
</form>
EOD;
        echo $form;

        // SHOW THE CONTENTS OF THE ERROR LOG
        echo '<pre>';
        print_r(file_get_contents($path . $name));
        echo "</pre>" . PHP_EOL;
    }
}

$out = ob_get_contents();
if (empty($out)) echo '<h3>Good News! No error_log found.</h3>';

I was getting that on Penguin / Chihost for a long time because suhosin doesn't run with PHP 5.4 but apparently they weren't changing the 'php.ini' on that server.  I just checked and that error has finally stopped.

I got those on ChiHost, too.  It didn't seem to affect my scripts - it just filled up the error logs.  When I told them about it, they fixed it and the problem went away.
