测试.php
<?php
$db = mysql_connect('localhost', 'mysql_user', 'mysql_password');
if (!$db) {
die('Could not connect: ' . mysql_error());
}
$filename = "num.txt";
$handle = fopen($filename, 'r');
$data = fread($handle, filesize($filename));
$rowsArr = explodeRows($data);
function explodeRows($data) {
$rowsArr = explode(";", $data);
return $rowsArr;
}
for($i=0;$i<count($rowsArr);$i++) {
$cols = explodeRows($rowsArr[$i]);
mysql_select_db("test", $db);
$query = sprintf('INSERT INTO voter (fname, lname, add) VALUES ("%s", "%s", "%s")', $cols[0], $cols[1], $cols[2]);
if (!mysql_query($query,$db))
{
die('Error: ' . mysql_error());
}
echo "1 record added";
}
fclose($handle);
mysql_close($db);
?>
上面的输出:
