What is the php.ini setting that allows for visibility of syntax errors when compiling?

I am using GoDaddy & on the SPECIFIC account I have (for a customer), the GoDaddy rep doesn't even know what I'm taking about.

I know, I know, a number of you have told me to get off GoDaddy. I don;t always have that choice.

Thanks

I think this is what you want.  http://us1.php.net/manual/en/function.error-reporting.php
// Report all PHP errors (see changelog)
error_reporting(E_ALL);

Open in new window

GoDaddy reps are not coders, you shouldn't expect them to know or answer these kinds of questions.  They are probably told not to anyway.

Here is what I use:

<?php
ini_set('dosplay_errors', TRUE);
ini_set('log_errors', TRUE);
error_reporting(E_ALL);

Open in new window

But with that said I have still found GoDaddy installations where I could not get the errors displayed and could only get them logged.  The following script can be placed in the WWW root.  It will find and display the error logs.  Not as great as having real-time information, but at least if you get the screen of death you can get a clue from the logs.

<?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);
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>";
    }
}

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

Open in new window

You may have to define the error_log file in php.ini with something like this.

log_errors = On
log_errors_max_len = 1024
error_log = error_log

Note that on Godaddy Linux hosting, you can put a partial 'php.ini' file in the web root but that does not work on their Windows hosting.  On the Windows hosting, it kills the server 'php.ini' file.

There isn't any way to put parameters into php.ini so that EVERY php program reports syntax errors rather than a blank screen?

This seems to be the default at all the other hosts I use and even most of my other GoDaddy accounts.

Thanks

On most of the accounts I use, there is no access to 'php.ini' so I have to use the inline versions that Ray and I have shown you.  If you were the hosting company, I think you would find that many, maybe even most, people do not want the errors to show.  So the default is going to be to not show anything that isn't a fatal error.

Most professional web developers will suppress the display of errors, if only to avoid showing something that looks unprofessional when a "Sorry,..." message could be displayed instead.  The error logs will contain the diagnostic information.  And as you can see from your experience with GoDaddy, the error logs are where you have to go for dependable access to the diagnostics.
