Hi,
I have two lines here as follows:
1 -0.123701962557954E+03 0.460967618024691E+02
-0.123547659000000E+03 0.462591090000000E+02
What I am trying to do here is to only have
1 -0.123701962557954E+03 0.460967618024691E+02 be the output so I
can do further processing with it, however, with the code I have in the
following, I have both lines in the output. 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.
Alice

[^0-9] means not a digital....
^[0-9] is the right way..
Thanks for your help. I cannot imagine that I have missed that.
