row is a row record in MySQL

row is a term in MySQL, referring to the row in the database table One line record. Each row of records contains one or more columns that store the data for that record.

Usage of row in PHP

In PHP, row can be represented as an associative array, where the key is the column name and the value is the value corresponding to the column. Row can be obtained using the following method:

• mysqli_fetch_row(): Returns a row of records as a numerically indexed array.
• mysqli_fetch_assoc(): Returns a row of records in the form of an associative array.

Advantages of row

Using row has the following advantages:

• Convenient access to column data: Column data can be accessed directly using the column name without specifying an index.
• Flexibility: row can store different types of data, and columns can be added and deleted dynamically.
• Performance: Getting row in the form of an associative array has higher performance.

#row example

Suppose there is a table named users which contains id, name and email columns. The following PHP code will get the first row of records in the table and print its column values:

<code class="php"><?php
$mysqli = new mysqli("localhost", "username", "password", "database");

$result = $mysqli->query("SELECT * FROM users LIMIT 1");

$row = $result->fetch_assoc();

echo "ID: " . $row['id'] . "<br>";
echo "Name: " . $row['name'] . "<br>";
echo "Email: " . $row['email'] . "<br>";
?></code>

Output:

<code>ID: 1
Name: John Doe
Email: john.doe@example.com</code>
