How to Correctly Use PDO Parameterized Queries with LIKE Statements for Case-Insensitive Searching?

Creating a PDO Parameterized Query with a LIKE Statement

When crafting a PDO parameterized query with a LIKE statement for case-insensitive matching, the placeholder syntax and execution method may differ from the provided example.

In the initial attempt, the placeholder for the WHERE clause is specified as "?%" within quotation marks. However, to allow for flexible matching, it should be modified to simply "?".

Moreover, the value provided in the execute() method also requires adjustment. Instead of passing a fixed value with a trailing wildcard ("value%"), a wildcard-suffixed value should be used ("value%").

The correct syntax for this PDO parameterized query with a LIKE statement is as follows:

$query = $database->prepare('SELECT * FROM table WHERE column LIKE ?');
$query->execute(array('value%'));

while ($results = $query->fetch()) {
    echo $results['column'];
}

By using this modified query, you can successfully perform case-insensitive pattern matching on the specified column.
