unexpected ']', expecting T_STRING or T_VARIABLE or T_NUM_STRING

Flamekorn

I'm getting

"Parse error: syntax error, unexpected ']', expecting T_STRING or T_VARIABLE or T_NUM_STRING in /home/a6341481/public_html/response.php on line 34"

when I submit the form of my site. This is the code I have from line 17 to 36:

if (strlen($username) <0)
{
die("Please enter a valid username");
}
if (strlen($username) >20)
{
die("Please enter a valid username");
}

if (strlen($username) == 0 )
{
die("Please enter a valid username");
}

//saving record in a text file
$pfw_file_name = "db.csv";
$pfw_first_raw = "username,boss[]\r\n";
$pfw_values = "$username,$boss[]\r\n";
$pfw_is_first_row = false;
if(!file_exists($pfw_file_name))

You forgot to put a $ sign in front of boss on line 33.

$pfw_first_raw = "username,boss[]\r\n"; << Here

You should take a thinking on these:

I dont know if this is meant $username, $boss
or maybe username, boss
$pfw_first_raw = "username,boss[]\r\n";

Here you can not have [].
You could have $boss[0] or $boss['something']
Or just just $boss if the varable is NOT an array
$pfw_values = "$username,$boss[]\r\n";

//saving record in a text file
$pfw_file_name = "db.csv";
$pfw_first_raw = "username,boss[]\r\n";
$pfw_values = "$username,$boss[]\r\n";
$pfw_is_first_row = false;
if(!file_exists($pfw_file_name))

The error keeps giving the same even when i try without the brackets or

$pfw_first_raw = "$username,$boss[]\r\n";

The strange thing is php doesnt see any errors when I put him to debug its only when I send the form.

Have you tried removing them all

//saving record in a text file
$pfw_file_name = "db.csv";
$pfw_first_raw = "username,boss\r\n";
$pfw_values = "$username,$boss\r\n";
$pfw_is_first_row = false;
if(!file_exists($pfw_file_name))

I believe the first error you got was not due to the missuse of empty backets, but rather due to not properly dealing with variables in strings

$array = array('whatever');
echo "This will not work $array[]";  // This should be the error you got
echo "This will not work either, but at least the array variable is recognized {$array[]}";

You can't use empty brackets on arrays except when assigning to them.

$arr = array();

// add a new element 'val' with a key that is one greater than previously highest positive integer
// or 0 if not applicable.
$arr[] = 'val';
$arr[] = 'val2'; // and yet another element with a one higher integer key than before.

$arr2 = array();
$arr2['string_key'] = 'val';
$arr2[] = 'val2'; // this will get key 0

echo $arr[]; // Syntax error.
