How can one effectively use the implode() function in PHP to concatenate array values for SQL queries?

When constructing SQL queries in PHP, it is common to concatenate array values into a string to use in the query. The implode() function in PHP can be effectively used for this purpose by joining array values with a specified delimiter. This can help prevent SQL injection vulnerabilities and make the query more readable. 

// Example of using implode() to concatenate array values for SQL queries
$colors = ['red', 'green', 'blue'];
$colorsString = "'" . implode("', '", $colors) . "'";

$sql = "SELECT * FROM products WHERE color IN ($colorsString)";
echo $sql;
