Where the class is defined as follows: class PDOMultiLineInserter inserts), the following errors occurred:". I have created a class that performs multi-line that is used as follows: $pdo->beginTransaction() If you have lots of columns to put together, and one or more are very long, you could also build an inner loop to do the same thing and use implode() to assign the values clause to the outer array. The advantage of this approach is that you don't copy and re-copy the SQL statement you've so far assembled with each concatenation instead, PHP does this once in the implode() statement. Mysql_query('INSERT INTO table (text, category) VALUES '.implode(',', $sql)) The fastest and most memory efficient way to build a large string, such as for inserting hundreds of rows at one, is to take advantage of the implode() function and array assignment. I have tried numerous ways and still can't solve it. Primarily, this means you want to avoid concatenation. Can't insert the data into database 0.00/5 (No votes) See more: HTML PHP MySQL I tried to insert the data and the alert still say that I successfully registered but when I checked on the sql, the data is not there. Basically, when working with large strings, you want to minimize unnecessary copying. That said, it sounds like you might be running into string-handling problems in PHP, which is really an algorithm problem, not a language one. This tutorial will cover how to create a basic PHP script for inserting data, and an HTML form to take user input from a webpage and pass it to the PHP script. Assembling one INSERT statement with multiple rows is much faster in MySQL than one INSERT statement per row. A PHP script is a convenient way to accept information submitted from a website's HTML form and insert it into a MySQL/MariaDB database.
