通过php从文本区域字段的每一行插入数据库

我建议在行尾使用分隔符，然后使用explode（）将其转换为数组，以下是您可以做的。

//Make sure your text have (,) comma at the end of every line
$text = 'My Name,
         My Full Name, 
         24';
//Convert it into an array
$text = explode(',', $text);
//fetch the value and assign it to variables then do an insert operation
//Use mysql_real_escape_string() to escape SQL injections.
$name = mysql_real_escape_string($text[0]);
$FullName = mysql_real_escape_string($text[1]);
$age = mysql_real_escape_string($text[2]);

然后您可以创建这样的查询。

$query = "INSERT INTO persons(name, fullName, age) values($name, $fullName, $age)";
$result = mysql_query($query);

// assuming the text area value is in $_GET["text"]
$lines = explode("'n", $_GET["text"]);
foreach($lines as $line) {
    list($name, $fullName, $age) = explode(" | ", $line);
    mysql_query("INSERT INTO table (name, fullname, age) VALUES ('$name', '$fullName', $age)");
}

希望这有帮助：

// assuming textarea name is $_POST['data']
$_POST['data'] = 'Jane | Jane Doe | 23
    zxc
sadas
 John | John Doe | 48
';
// Set and trim data 
$data = (array_key_exists('data', $_POST)) ? trim($_POST['data']) : '';
if ($data !== '') {
    $lines = explode("'n", $data);
    $sql = 'insert into table (name, fullname, age) values ';
    $sql_parts = array();
    foreach ($lines as $line) {
        $sql_part = array(
            'name' => null,
            'full_name' => null,
            'age' => null,
        );
        // If no divider found, skip this line
        if (strpos($line, ' | ') === false)
        {
            continue;
        }
        list($sql_part['name'], $sql_part['full_name'], $sql_part['age']) = explode(' | ', $line);
        // For the sake of this example
        // i will assume all fields are required
        // so let's check for that:
        foreach ($sql_part as $key => $item) {
            // Trim and sanitize the data:
            $item = mysql_real_escape_string(trim($item));
            // If any item is empty continue to the next line of data
            if ($item === '') {
                continue 2;
            }
            $sql_part[$key] = "'".$item."'";
        }
        $sql_parts[] = '('.implode(',', $sql_part).')';
    }
    if (empty($sql_parts) === false) {
        $sql .= implode(',', $sql_parts);
        mysql_query($sql);
    }
}
