    <p>I'm trying to import a huge txt in mysql.<br> it is my first attempt to use php and mysql so I'm not sure where is the problem.<br> I have a txt of almost the 4 million row and I need to store it in a db.<br> I wrote this pice of php to do the job:<br></p> <pre><code>$con=mysqli_connect('localhost', 'root', 'root', 'commuting'); if (mysqli_connect_errno()) { echo "Failed to connect to MySQL: " . mysqli_connect_error(); } $handle = fopen("matrix_pendo2001.txt", "r") or die("Couldn't get handle"); if ($handle) { while (!feof($handle)) { $line = fgets($handle, 4096); $a = substr($line,0,3); $b = substr($line,4,3); $c = substr($line,8,1); $d = substr($line,10,1); $e = substr($line,12,1); $f = substr($line,14,3); $g = substr($line,18,3); $h = substr($line,22,3); $i = substr($line,26,1); $l = substr($line,28,2); $m = substr($line,31,1); $n = substr($line,33,1); $o = substr($line,35,8); $sql="INSERT INTO ita (ProvRes, ComRes, Sesso, Motivo, Luogo, ProvLav, ComLav, StatExt, MercPrev, Mezzo, Ora, Tempo, Num) VALUES ('$a', '$b', '$c', '$d', '$e', '$f', '$g', '$h', '$i', '$l', '$m', '$n', '$o')"; if (!mysqli_query($con,$sql)) { die('Error: ' . mysqli_error($con)); } echo "record '&lt;b&gt;" . $line . "'&lt;/b&gt; added. &lt;br/&gt;"; } fclose($handle); } mysqli_close($con); </code></pre> <p>The script seems to work well, but I can't get all the row in the db.<br> after less than 1 million the script ends without apparent error.<br> I have set the max_execution_time to 0 and increased the memory_limit to 2048MB but nothing change.</p>

    2. CODon't do it this way. In fact, don't use PHP at all. Look at `LOAD DATA INFILE` in the [MySQL Reference](http://dev.mysql.com/doc/refman/5.6/en/load-data.html). It'll do the job faster and more reliably.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
