Is Using Multiple INSERT Statements in a Single PHP Query Efficient?

Executing Multiple INSERT Statements in a Single PHP Query

In PHP, it's not recommended to execute multiple INSERT statements in one query using the mysql_query function. The sample code provided in the question:

$string1= "INSERT INTO....;";
$string1 .= "INSERT INTO....;";
$string1 .= "INSERT INTO....;";
mysql_query($string1) or die(mysql_error()); 

is not an optimal approach for inserting multiple records into MySQL tables.

Preferred Approach: Single Insert Query

Instead, it's preferable to use a single INSERT query that inserts multiple values in one go. This method is more efficient and concise:

$query = "INSERT INTO table_name (column1, column2) VALUES (1, 2), (3, 4), (5, 6);";
mysql_query($query) or die(mysql_error());

By grouping the values for each column in parentheses and separating them with commas, you can insert multiple rows with a single query.

Benefits of Single Query Approach

Using a single query to insert multiple records offers several advantages:

• Improved Performance: Executing a single query is significantly faster than running multiple individual INSERT statements, especially for large inserts.
• Reduced Code Complexity: It eliminates the need to concatenate multiple INSERT strings and reduces the risk of errors.
• Enhanced Readability: A single query is easier to read and maintain than multiple statements.
