PHP server error

hi all, i have been making a php mysql login, however it is throwing up a 500 server error and i have no clue why, here's the code:

<?
if (isset($_POST['submitted'])) {
	
	$errors = array();
	
	if (empty($_POST['first_name'])) {
		$errors[] = 'You forgot to enter your First Name.';
	} else {
		$fn = trim($_POST['first_name']);
	}
	
	if (empty($_POST['last_name'])) {
		$errors[] = 'You forgot to enter your Last Name.';
	} else {
		$ln = trim($_POST['last_name']);
	}
	
	if (empty($_POST['email'])) {
		$errors[] = 'You forgot to enter your email address.';
	} else {
		$e = trim($_POST['email']);
	}
	
	if (!empty($_POST['pass1'])) {
		if ($_POST['pass1'] != $_POST['pass2']) {
			$errors[] = 'Your password did not match the confirmed password.';
		} else {
			$p = trim($_POST[['pass1']);
		}
	} else {
		$errors[] = 'Your forgot to enter your password.';
	}
	
	if (empty($errors)) {
		require_once ('mysqli_connect.php');
		$q = "insert into users (first_name, last_name, email, pass, registration_date) values ('$fn', '$ln', '$e', sha1('$p'), now() )";
		$r = @mysqli_query ($dbc, $q);
		if ($r) {
			echo '<h1>Thank you!</h1>
			<p>You are now registered</p>';
		} else {
			echo '<h1>System error</h1>
			<p>You could not be registered due to a system error</p>';
			echo '<p>' . mysqli_error($dbc) . '<br /><br /> Query: ' . $q . '</p>';
		}
		mysqli_close();
		exit();
	} else { 
	echo '<h1>Error!</h1>
	<p>The following errors occurred:<br />';
	foreach ($errors as $msg) {
		echo " - $msg<br />\n";
	}
	echo '</p><p>Please try again.</p>';
	}
}
?>
<h1>Register</h1>
<form action="register.php" method="post">
  <p>First Name:
    <input type="text" name="first_name" size="15" maxlength="20" value="<? if (isset($_POST['first_name'])) echo $_POST['first_name']; ?>" />
  </p>
  <p> Last Name:
    <input type="text" name="last_name" size="15" maxlength="40" value="<? if (isset($_POST['last_name'])) echo $_POST['last_name']; ?>" />
  </p>
  <p> Email Address:
    <input type="text" name="email" size="20" maxlength="80" value="<? if (isset($_POST['email'])) echo $_POST['email']; ?>" />
  </p>
  <p>Password:
    <input type="password" name="pass1" size="10" maxlength="20" />
  </p>
  <p>Confirm Password:
    <input type="password" name="pass2" size="10" maxlength="20" />
  </p>
  <p>
    <input type="submit" name="submit" value="Register" />
  </p>
  <input type="hidden" name="submitted" value="true" />
</form>

PHP:

can anyone see a reason why this may be?

 

$p = trim($_POST[['pass1']);

PHP:

Extra [ there

Also your server is not configured correctly if it is throwing a 500 error rather than telling you where the error is.

 

OMG silly mistake... ty v much

 

but it isn't only mistake webber, it can't just start to work if you deleted that [
It's server-side problem, not PHP. try to remove/rename .htaccess and it should work

 

If PHP hasn't been configured to properly handle errors, it could result in an internal server error.

 

internal server error = config error. It can't parse part of .htaccess or so on

 

A lot more than .htaccess can cause internal server errors. It could be an error within the PHP configuration file (php.ini), for example, which is what I was hinting at.

 

yep, sorry. Whole configuration of PHP can reult in ISO (500)

 

i have no .htaccess for this. all seams to work as soon as i got rid of the extra [ and it is working as intended

 

webber I think it's impossible. What do you use as web host? localhost? Or some webhosting?

 

it is hosted with birch hosting and the mysql is on the same server i guess. all the details are in the mysqli_connect.php which is used in the require_once function

 

yes I saw it
Umm, maybe screwed php.ini configuration but I am not sure. However, it doesn't matter if it works!

 

well its adding to the mysql table fine so it appears so
