问题 Issue 2. I am now getting an error in where the code is not inputting the actual ID number into the query... Here is the error: Query Error : You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1 The code has been updated to show the new code. (again) this time with a hidden script, and a few other tweaks. I've about lost hope on getting this to work. Issue 1 Solved: This line of code is brining back

问题 I've tried many ways in an attempt to insert a large amount of data parsed from a text file (200,000 lines of text gets parsed into the array in about 2 seconds on my server so I know that part isn't the issue). The mysqli_multi_query I'm using sends the queries in blocks of 5,000 (for some reason it refuses to do anything larger if I want to use multi_query more then once) OR if I split the text file down to 50,000ish rows I can insert them all at once in 2 seconds. If I do that then it

问题 I'm trying to learn php but when I attempt to connect to a mysql database, I get this error. I don't think anything is wrong with the code itself but perhaps there is an error on the hosts side? I'm using 000webhost so. Warning: mysqli::mysqli() [mysqli.mysqli]: (28000/1045): Access denied for user 'a7976620_db1user'@'localhost' (using password: YES) in /home/a7976620/public_html/index.php on line 17 Here is my php: <?php $servername = "localhost"; $username = "a7976620_db1user"; $password =

问题 My table's collation is utf8_general_ci. My pages are encoded with UTF-8 (without BOM). Within my pages, my Equiv meta tag sets character set to utf8 My data has Turkish characters in it. When i output them, it's not showing them as it should be but when i do $db->set_charset("utf8"); , it works. Why do i have to use $db->set_charset("utf8"); even though everything is utf-8 encoded? 回答1: The data is stored as UTF-8 in MySQL, but the PHP's client connection collation is not. Which is why you

问题 The problem I just got is, the $update_stmt->execute() is ok, and data in database already update but, $update_resultrow = $update_stmt->num_rows; return 0 ?

WHERE ID = ?"; if ($update_stmt = $conn -> prepare($update_sql)) { if ($update_stmt->bind_param("si", $newname, $acc_id ) ) {

问题 I want to run multiple mysql queries( not concurrently). I am using prepared statements for doing so. This is a gist of my code : <?php if(isset($_GET['username'])&&isset($_GET['activationid'])){ require_once("../database/db_connect.php"); $stmt= $mysqli->stmt_init(); $stmt->prepare("Select username FROM users where username= ? AND activationid= ?"); $username=$_GET['username']; $activationid=$_GET['activationid']; $stmt->bind_param("ss",$username,$activationid); $stmt->execute(); $row=$stmt-
