I'm trying to connect to mysql db in phpstorm, but I don't succeed.
I will appreciate your help.
<?php
$servername = "http://localhost:8012";
$username = "root";
$password = "";
// Create connection
$conn = new mysqli($servername, $username, $password);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}else{
die("Connected successfully");
}
The error is:502 Bad Gateway
You can connect database like that:
<?php
$servername = "localhost";
$username = "root";
$password = "";
$database = "";
$port = "8012";
// Create connection
$conn = new mysqli($servername, $username, $password, $database, $port);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}else{
die("Connected successfully");
}
<?php
$servername = "localhost:8012";
$username = "root";
$password = "";
$database = "dbname";
// Create connection
$conn = mysqli_connect($servername, $username, $password,$database) or die(mysqli_error($conn);
echo "Connection Successful";

When I run this code it shows parse error. Can anyone help me with this?
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "form";
// Create connection
$conn = new mysqli($servername, $username,$password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " .$conn->connect_error);
}
SELECT * FROM my_db;
$conn->close();
You should use php tags and remove those ">" also you should use mysqli_query to query the data from mysql
<?php
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "form";
// Create connection
$conn = new mysqli($servername, $username,$password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " .$conn->connect_error);
}
$query = mysqli_query($conn,"SELECT * FROM my_db");
$conn->close();
?>
My table has 2 fields a primary with auto increment and then entry_id
why does the below not insert in the table:
<?php
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "ecolog";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$entry_id = 5;
$sql = "INSERT INTO orders (entry_id) VALUE ('$entry_id')";
$conn->close();
?>
but when adding a error check it does?
<?php
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "ecolog";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$entry_id = 5;
$sql = "INSERT INTO orders (entry_id) VALUE ('$entry_id')";
if ($conn->query($sql) === TRUE) {
echo "";
} else {
echo "Error: " . $sql . "<br>" . $conn->error;
}
$conn->close();
?>
cant get my head around why this would be happening.
I want to fetch time column from mysql database and to compare with current time.
It should execute only if it matches with the current time.
Please tell me a MySql query or php code to do this.
I am new to php.
Try This:
<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$today = date("h:i a")
$sql = "SELECT * FROM Table_name WHERE SUBSTRING_INDEX(time, ' ', 2) = '".$today."'";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
// execute you code
} else {
}
$conn->close();
?>
Try this: Updated Code
<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$today = date("h:i a")
$sql = "SELECT * FROM Table_name WHERE time = $today";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
// execute you code
} else {
}
$conn->close();
?>
I've following code of a function in a PHP file titled sample.php :
function deleteValue($value) {
$servername = "localhost";
$username = "root";
$password = "jumbo";
$dbname = "demo";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "DELETE FROM user WHERE value = '$value'";
if ($conn->query($sql) === TRUE) {
$conn->close();
return true;
} else {
$conn->close();
return false;
}
}
Actually, in this file(sample.php) there are too many such functions which repeats the following database connectivity code :
$servername = "localhost";
$username = "root";
$password = "jumbo";
$dbname = "demo";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
Then, I created one file titled db.php in the same folder and added the above code to it. Using require_once('db.php'); at the beginning of file 'sample.php'I included the file to the above code. Finally the code appeared as follows :
require_once('db.php');
function deleteValue($value) {
$sql = "DELETE FROM user WHERE value = '$value'";
if ($conn->query($sql) === TRUE) {
$conn->close();
return true;
} else {
$conn->close();
return false;
}
}
Now it's giving me 500 Internal Server error.
Even instead of including the file I tried by pasting the whole code from db.php at the beginning of file sample.php as follows but still I get 500 Internal Server Error.
$servername = "localhost";
$username = "root";
$password = "jumbo";
$dbname = "demo";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
function deleteValue($value) {
$sql = "DELETE FROM user WHERE value = '$value'";
if ($conn->query($sql) === TRUE) {
$conn->close();
return true;
} else {
$conn->close();
return false;
}
}
Can someone please correct the mistake I'm making in my code?
Thanks in advance.
I will suggest you that in db_config.php file you should use only database config and functions like this:
$servername = "localhost";
$username = "root";
$password = "jumbo";
$dbname = "jumbo_jet";
$conn = new mysqli($servername, $username, $password, $dbname);
if ($conn->connect_errno) {
echo "Failed to connect to MySQL: (" . $conn->connect_errno . ") " . $conn->connect_error;
}
And in common.php use code like this:
require_once("db_config.php");
function deleteToken($receivedToken) {
global $conn;
$sql = "DELETE FROM user_login WHERE token = '$receivedToken'";
if ($conn->query($sql) === TRUE) {
return true;
}
return false;
}
I hope it will work for you. If anything else then let me know.
<?php
$host = "localhost";
$username = "root";
$password = "";
$db = "mineforums";
$connect = mysqli_connect($host, $username, $password, $db) or die(mysqli_error($connect));
?>
That is my php code to connect to my database. Whenever I try to just connect though it doesnt do anything. The way I have my login-form setup is the action will be to this code and then doesnt do anything and when I return to my index it says database not selected because if you're logged in it says 'Welcome, {username}'
you could split the process
<?PHP
$host = "localhost";
$username = "root";
$password = "";
$db = "mineforums";
$connect = mysql_connect($host, $username, $password)OR DIE("Could Not Connect To Server". MySQL_Error());
if($connect) {
mysql_select_db($db)OR DIE("Could Not Select Databse". MySQL_Error();
}
?>
