无法使用PHP访问远程MYSQL数据库

Question

I have problem connecting SQL with php. I don't even get an SQL error, just an ugly PHP error message:

"Warning: mysql_connect(): in C:\\wamp\\www\\guildcreator\\include\\sql_conn.php on line 19 Call Stack Time Memory Function Location 1 0.0004 252040 {main}( )
..\\sub.php:0 2 0.0009 255208 include( 'C:\\wamp\\www\\guildcreator\\include\\sql_conn.php' ) ..\\sub.php:5 3 0.0009 256344 mysql_connect ( )"

At first I thought that I wasn't creating a connection to the server. I tried various different combinations of the same address, with and without the port number. I don't understand why I am getting this error, because if mysql_connect fails I should be seeing the die() message.

I read something about the mysql_ functions being old and unsupported, maybe that's my problem? Any help would be great :-)

Here's the code that I am using:

$hostname = 'lolisrael.co.il:3306';
$sqluser = 'XXXXXX';
$sqlpass = 'XXXXXXXXX';

$link = mysql_connect($hostname, $sqluser, $sqlpass) or die("error zzzzz"); 
if ($link)
    $db = mysql_select_db('_db', $link) or die("no db found");

the submite page for reference:

<?php 
if(isset($_POST['free_text'])) 
{
    echo "<p>".$_POST['free_text']."</p>";
    include "include/sql_conn.php";
    if(isset($db))
    {
        $free_text = mysql_real_escape_string($_POST['free_text']);
        $sql = "INSERT
            INTO
            orhalimi_test_conn(free_text)
            VALUES ('{$free_text}')";
        if(mysql_query($sql))
            echo "ITS WORK!!!";

    }
}           
?>

Answer 1

if ($link)
    $db = mysql_select_db('_db', $link) or die("no db found");

why would you use the mysql_select_db() function into a variable? :) Also i recommend you to use MySQLi or PDO as from the version 5.4 the mysql_* functions are considered deprecated.

Hey guys thanks for help, but it seem the problem was a security config of the remote server.

I will look on mysqli trough.
