    copied!<p>I´m learning to work with files in php, first i made this function for writing to the file, it´s quite simple:</p> <pre><code>function zapis_do_suboru($zapisovany_subor, $obsah_suboru) { $pracovny_subor = fopen($zapisovany_subor,"w") or die("Chyba pri otvarani suboru"); fwrite($pracovny_subor, $obsah_suboru) or die("Nejde zapisovat do suboru"); fclose($pracovny_subor); echo "Zapis $zapisovany_subor prebehol uspesne."; } </code></pre> <p>Then I made function for reading from the file, but I was little stuck here, because my book is explaining how to read just one row, but then i googled little bit and found some solution and made this function for reading from file:</p> <pre><code>function citanie_zo_suboru($citany_subor) { $pracovny_subor = fopen($citany_subor,"r") or die("Chyba pri otvarani suboru"); $j = 0; while(!feof($pracovny_subor)) { $pole[$j] = array(fgets($pracovny_subor, 4096)); $j++; } fclose($pracovny_subor); return $pole; } </code></pre> <p>Then i wanted to test it, so i create two variables:</p> <pre><code>$subor = "textsubor.txt"; $text = &lt;&lt;&lt;_END Riadok1 blabla Riadok2 blabla Riadok3 meno suboru: $subor _END; </code></pre> <p>And this calling of functions:</p> <pre><code>zapis_do_suboru($subor, $text); echo "&lt;br /&gt;"; foreach (citanie_zo_suboru($subor) as $index =&gt;$popis) echo $popis."&lt;br /&gt;"; </code></pre> <p>But the problem is, that function citanie_zo_suboru is creating two-dimension array, so the output was only "array array array array". With print_r and little bit of trying i found out, that when i change:</p> <pre><code>foreach (citanie_zo_suboru($subor) as $index =&gt;$popis) echo $popis."&lt;br /&gt;"; </code></pre> <p>to:</p> <pre><code>foreach (citanie_zo_suboru($subor) as $index =&gt;$popis) echo $popis[0]."&lt;br /&gt;"; </code></pre> <p>it's doing exactly what i wanted. Can someone tell me why my function is creating two-dimension and not just classic one-dimension array? I would be really grateful if you could. Thanks</p>
