preg_split

[lindm]

I have the following code extract data from a text file:

$contents = file("textfile.txt"); //chose file

foreach($contents as $line_value)
{
list($cat, $int, $id, $num) = preg_split("/(\t| )/",$line_value);

    $cat = str_replace('#', '', $cat);

    $number[$cat][$int][$id]= trim($num);
}

 

The text file contents normally looks like this:

#RES -1 6922 144897.52
#RES -1 6970 16894.59
#RES -1 6981 1110.00
#RES -1 6993 500.00

 

echo $number["RES"][-1][6981]; would return 1110.00

 

All fine. Now I have a text file where the whitespace varies like this:

#RES -1 6922 144897.52
#RES -1 6970       16894.59
#RES -1 6981       1110.00
#RES -1 6993 500.00

 

echo $number["RES"][-1][6981]; would then return 0 which I of course don't want. Any easy way to solve this?

$contents = file_get_contents("textfile.txt"); //chose file
preg_match_all('~(0-9.]+)$~',$contents,$data);
print_r($data);

Or you could just split, as you were before, but with /[\t ]+/

Crayon Violent: Seems preg_match_all requires a string.

 

salathe: Suggestion seems to work fine!

 

Thanks all!

that's why i changed your file() to file_get_contents()

Now I see! My mistake. Good solution!
