Topic awaiting preservation: PHP: undefined offset reading file

My code is generating an undefined offset. I have a text file filled with lines that may contain comments ( prefix: "//" ), or data: in the form: [number]=[string] . Like an ini file, if the key was always a number in the range 0-31.

I'm getting a PHP notice when trying to read. My data is being correctly read. But I need to fix the error causing the Notices.

PHP output: ed offset: 1 in image.php on line 170
PHP Notice: Undefined offset: 1 in image.php on line 170
PHP Notice: Undefined offset: 1 in image.php on line 170
PHP Notice: Undefined offset: 1 in image.php on line 170
PHP Notice: Undefined offset: 1 in image.php on line 170 # repeating several times

(1) To double check: if split() returns false, are these two statements
equivalent in PHP?
if( !$result) continue;
# AND:
if( $result == False ) continue;

# first code; works as intented, except it outputs ugly notices
$lines = file( $path ) or die( "image.php: could not open: $path" );
	foreach( $lines as $line_num => $cur_line ) {
		$cur_line = rtrim( $cur_line );
		# this next line causes notice:
		list($cur_day, $cur_result) = split("=", $cur_line, 2); # this is line #170

# so I tried to validate it, fixing only partial errors: All but 2 errors remain
$lines = file( $path ) or die( "image.php: could not open: $path" );
	foreach( $lines as $line_num => $cur_line ) {
	    $result = split("=", $cur_line, 2);

		# now this next line causes error: "Undefined offset 1"
	    if(! $result or !$result[0]) continue; # this is line #170
		if($result == False or !$result[1]) { continue;  } # not enough elements
		$cur_day = $result[0];
		$cur_result = $result[1];

now the error is:

T: 1 in image.php on line 170
PHP Notice: Undefined offset: 1 in image.php line 170
"Undefined offset 1 in image.php";

(2) What does the error "T: 1 in <file> on line <number>" mean?
(3) How do I fix the error Undefined offset?

(1) yes.
(2) means you're wreaking some weird havoc that ends up swallowing the first few characters of (Undefined offse)t 1 in image.php on line 170, and acidintially also capitalizing the T .
(3) you'll need to use !isset($resultnt) if you want to check for that.
(3b) what you really want to do most likel if (!$result or count($result) != 2) { continue; }
