I don't know where the problem is, but I would use explode instead of
sscanf, so try if this code works:
<?php
$fichero="62007lg.txt";
$buffer = file($fichero,FILE_IGNORE_NEW_LINES); // Remove new lines in array
$lineas = count($buffer);
foreach($buffer as $linea){
$array = explode(" ",$linea);
$mday[]=$array[0];
$mmonth[]=$array[1];
$myear[]=$array[2];
$mhour[]=$array[3];
$mmin[]=$array[4];
$mtemp[]=$array[5];
$mhum[]=$array[6];
$mdew[]=$array[7];
$mbaro[]=$array[8];
$mwind[]=$array[9];
$mgust[]=$array[10];
$mwdir[]=$array[11];
$mrlastm[]=$array[12];
$mdai[]=$array[13];
$mrmon[]=$array[14];
$mryear[]=$array[15];
$mheat[]=$array[16];
echo"$array[0] $array[1] $array[2] $array[3] $array[4]
$array[5] $array[6] $array[7] $array[8] $array[9] $array[10]
$array[11] $array[12] $array[13] $array[14] $array[15] $array[16]
<br>";
}
?>

Thanks Tijnema for your code, but I have the same problem, the echo
doesn´t print all the values and stop without error message, why? perhaps
the file it's too long?
