Here is the code: $file = "test.txt"; $fp = fopen($file, "r"); $lines = file($file); foreach($lines as $line_num => $line) { if (preg_match("/([^0-9]+\s+)(\-?\d+\.?\d+(\+?E?\d+)?){2}/", $line)) echo $line; } Could anyone please tell me that even when I specify that the line has to start with [^0-9]+\s with one occurrence, why I still get -0.123547659000000E+03 0.462591090000000E+02? Thanks a lot for your help.
