I am using PHP to send data from a form to mysql database, when I use this code:
$sql = "CREATE TABLE MyGuests (
id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
name VARCHAR(30) CHARACTER SET utf8 COLLATE utf8_unicode_ci NOT NULL,
phone VARCHAR(60) NOT NULL,
password VARCHAR(60) CHARACTER SET utf8 COLLATE utf8_unicode_ci NOT NULL,
email VARCHAR(50),
pelak VARCHAR(50) CHARACTER SET utf8 COLLATE utf8_unicode_ci,
reg_date TIMESTAMP
)";
it works perfectly, but when I use:
$field_table = $_POST['phone'];
$sql = "CREATE TABLE '{$field_table}' (
id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
name VARCHAR(30) CHARACTER SET utf8 COLLATE utf8_unicode_ci NOT NULL,
phone VARCHAR(60) NOT NULL,
password VARCHAR(60) CHARACTER SET utf8 COLLATE utf8_unicode_ci NOT NULL,
email VARCHAR(50),
pelak VARCHAR(50) CHARACTER SET utf8 COLLATE utf8_unicode_ci,
reg_date TIMESTAMP
)";
it create table in phpmyadmin but gives an error:
"#1146 - Table 'username.table_name' doesn't exist"

I only want to create the table once if it doesn't exist. Will this code create a new table every time? If yes, how do I prevent it?
$queryCreateUsersTable = "CREATE TABLE IF NOT EXISTS EmailList (
`ListName` varchar(100) COLLATE utf8_unicode_ci NOT NULL,
`FirstName` varchar(100) COLLATE utf8_unicode_ci NOT NULL,
`Email` varchar(100) COLLATE utf8_unicode_ci NOT NULL,
`ID` varchar(100) COLLATE utf8_unicode_ci NOT NULL,
`IP` varchar(100) COLLATE utf8_unicode_ci NOT NULL,
`ConfirmedEmail` tinyint(1) DEFAULT NULL,
`Subscribed` tinyint(1) DEFAULT 0,
UNIQUE KEY `ID` (`ID`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;";
if(!$conn->query($queryCreateUsersTable))
{
echo "Table creation failed: (" . $dbConnection->errno . ") " . $dbConnection->error;
}
CREATE TABLE IF NOT EXISTS means it will only create the table if it is not present.
Exactly as what CREATE TABLE IF NOT EXISTS means. Create a table if table does not exist.
Therefore, no it does not.
I am gettin XML data which header has utf8 setted:
<?xml version="1.0" encoding="utf-8"?>
I download it using CURL and it is downloaded correctly with UTF8 chars.
I parse that downloaded xml files using SimpleXML using this code:
<?php
class XMLParser{
public function __construct(){
}
public function parseFile($path){
$xml = '';
if(!is_null($path)){
$file = file_get_contents($path);
if(!is_null($file)){
$xml = new SimpleXMLElement($file);
}
else{
echo 'there is no file';
}
}
else{
echo 'Wrong path!';
}
return $xml;
}
}
?>
And send it to database calling PDO and stored procedures, connect script has defined utf8:
$this->PDO->setAttribute(PDO::MYSQL_ATTR_INIT_COMMAND, "SET NAMES 'utf8'");
Each table has utf8_general_ci
But in table are chars like this:
León de Huánuco - Cienciano

Now, I use this query in order to store the values in the table academic_candidate
session_start();
$query = "SELECT * FROM academic_candidate WHERE degree = '$degree'";
$result = mysql_query($query);
$count = mysql_num_rows($result);
if($count > 0){

My problem is that stores all the values on the table academic_candidate table but the c_id is 0 . What can I do in order to take the candidate.c_id?
You're passing literal values to your INSERT INTO statement.
Consider the difference:
SELECT 'bar' FROM foo;
SELECT bar FROM foo;
Here's a demo on SQLFiddle.
Looking at your query:
SELECT '$degree'
Is not the same as:
SELECT degree
One of these is simply echoing whatever value you pass in, the other is actually selecting a column from the DB.
I'd like to find the number of posts for each user grouped by month.
I'm currently using INT(10) unsigned to store the date of posts.
what would be a super fast way to do this?

This is the table, I'm talking about, I'd like to display the number of posts for each user for each mont, such as: september 2012, User X, N posts etc..
The query I'm using after the help from #fthiella is:
SELECT
DATE_FORMAT(FROM_UNIXTIME(`date`), '%Y-%m') as YearMonth, username, COUNT(*) as Posts
FROM
media
WHERE username = 'foobar'
GROUP BY 1
ORDER BY 1 DESC
thanks God it's fast enough, now I'll try to optimize in case it's not using an index, but for now with almost 1M record is doing good. cheers.
SELECT
DATE_FORMAT(FROM_UNIXTIME(`date`), '%Y-%m') as YearMonth,
username,
COUNT(*) as Posts
FROM
media
GROUP BY

username
