foreach ($inarr as $out) {
if ($out <> ’’) echo $out . "\n";
}

or instead of \n use <br> if writing to browser.

foreach ($inarr as $out) {
if ($out <> ’’) echo $out . "\n";
}

or instead of \n use <br> if writing to browser.

unfortunately it didint help. output is still the same.

$plik = fopen("wynik"," r");
$tablica = file('wynik');

foreach ($tablica as $out) {
if ($out <> ' ') echo $out."\n";
}

foreach ($inarr as $out) {
if ($out <> '') echo $out . "\n";
}

^^ ^ }

m$ style "not" (<>) and a space you're checking against. Try:
foreach ($tablica as $out) {
if (strlen($out) > 0) echo "$out\n";
}
Note:

if ($out != '') echo "$out\n";
could also be used, depending on your preferred coding style =)

HTH.

i' wondering whats wrong cause the result is the same..
here is my code:

echo '<br><textarea name="show" rows=24 cols=40>';

exec($program." >wynik");
$plik = fopen("wynik"," r");

$tablica = file('wynik');

foreach ($tablica as $out) {
if (strlen($out)>0 ) echo $out;

}
echo '</textarea>';
end the output in textarea is still the same:
I = 0
J = 0
sum2 = 0.000000
sum = 0.000000
Alpha 1 = 0.000000
Alpha = NaN
total = 0

percentage is = 0.000000%

....

i dont want to have this empty lines..

i dont want to have this empty lines..

Maybe try a simple regexp? Ex:

foreach ($tablica as $out) {
if ( strlen( $out ) > 0 && preg_match( "/\S/", $out, $tmp ) echo $out;
}

if in my file for example in the middle of the file is a word "blabla".
How than i can find this word?
i'd like to use in inside this code if its possible and make this
"blabla" bold <b>:

$data = file('file.txt' ); foreach($data as $line) {
if (strlen(trim($l ine)) > 0) {
echo $line; } }
