mysql中单词之间没有空格？

Question

I just looked at my MySQL data not all the words are joined up! For example if the word are David Greene , it will show them as DavidGreene .

How can I put the space where there should be one?

The data is dynamic by the way. Edit: here is the code:

<?php
$errorMsg = "";
// First we check to see if the form has been submitted 
if (isset($_POST['username'])){
    //Connect to the database through our include 
    include_once "scripts/connect_to_mysql.php";
    // Filter the posted variables
    $username = ereg_replace("[^A-Za-z0-9]", "", $_POST['username']); // filter everything but numbers and letters
    $country = ereg_replace("[^A-Z a-z0-9]", "", $_POST['country']); // filter everything but spaces, numbers, and letters
    $state = ereg_replace("[^A-Z a-z0-9]", "", $_POST['state']); // filter everything but spaces, numbers, and letters
    $city = ereg_replace("[^A-Z a-z0-9]", "", $_POST['city']); // filter everything but spaces, numbers, and letters
    $accounttype = ereg_replace("[^a-z]", "", $_POST['accounttype']); // filter everything but lowercase letters
    $email = stripslashes($_POST['email']);
    $email = strip_tags($email);
    $email = mysql_real_escape_string($email);
    $password = ereg_replace("[^A-Za-z0-9]", "", $_POST['password']); // filter everything but numbers and letters
        $passport = ereg_replace("[^A-Za-z0-9]", "", $_POST['passport']); // filter everything but numbers and letters
    // Check to see if the user filled all fields with
    // the "Required"(*) symbol next to them in the join form
    // and print out to them what they have forgotten to put in
    if((!$username) || (!$country) || (!$state) || (!$city) || (!$accounttype) || (!$email) || (!$password) || (!passport)){

        $errorMsg = "You did not submit the following required information!<br /><br />";
        if(!$username){
            $errorMsg .= "--- User Name";
        } else if(!$country){
            $errorMsg .= "--- Country"; 
        } else if(!$state){ 
            $errorMsg .= "--- State"; 
       } else if(!$city){ 
           $errorMsg .= "--- City";

    } else if ($email_check > 0){ 
        $errorMsg = "<u>ERROR:</u><br />Your Email address is already in use inside our system. Please try another.";
    } else {

Try this:

<?php

$errorMsg = "";
// First we check to see if the form has been submitted 
if (isset($_POST['username'])) {
    //Connect to the database through our include 
    include_once "scripts/connect_to_mysql.php";
    // Filter the posted variables
    $username = filter_var($_POST['username'], FILTER_SANITIZE_STRING);
    $country = filter_var($_POST['country'], FILTER_SANITIZE_STRING);
    $state = filter_var($_POST['state'], FILTER_SANITIZE_STRING);
    $city = filter_var($_POST['city'], FILTER_SANITIZE_STRING);
    $accounttype = filter_var($_POST['accounttype'], FILTER_SANITIZE_STRING);
    $email = filter_var(filter_var($_POST['email'], FILTER_SANITIZE_EMAIL), FILTER_VALIDATE_EMAIL);
    $password = filter_var($_POST['password'], FILTER_SANITIZE_STRING);
    // Check to see if the user filled all fields with
    // the "Required"(*) symbol next to them in the join form
    // and print out to them what they have forgotten to put in
    if ((!$username) || (!$country) || (!$state) || (!$city) || (!$accounttype) || (!$email) || (!$password) || (!passport)) {

I have the impression that you have left out a very large part of your code. For instance the error message variable is not used inside your code after it is set. I haven't taken the time to change everything to mysqli. But I like to encourage you to make the switch. Please not that I haven't test the code, so that part is up to you.
