How can the use of Shortcodes in WordPress pages impact the execution of PHP code and the handling of database transactions?

Using Shortcodes in WordPress pages can impact the execution of PHP code and the handling of database transactions because Shortcodes are processed before the content is displayed on the page. This means that any PHP code within the Shortcode will be executed during the rendering of the page, potentially causing issues with database transactions or other PHP operations. To solve this issue, it's important to avoid executing database transactions or complex PHP operations within Shortcodes. Instead, separate the logic into functions or hooks that can be called at the appropriate time in the WordPress lifecycle. 

// Bad practice - executing database transaction within a Shortcode
function my_shortcode_function( $atts ) {
    // Execute database transaction
}
add_shortcode( 'my_shortcode', 'my_shortcode_function' );

// Good practice - separating logic into a function
function my_custom_function() {
    // Execute database transaction
}

// Call the function at the appropriate time
add_action( 'wp', 'my_custom_function' );
