How can using wildcards in SQL queries improve the accuracy of results when filtering data in PHP?
Using wildcards in SQL queries allows for more flexible and dynamic filtering of data in PHP. Wildcards such as '%' can be used in conjunction with LIKE statements to match patterns within the data, making it easier to search for specific information. This can improve the accuracy of results by allowing for partial matches, case-insensitive searches, and more complex filtering criteria.
// Example of using wildcards in an SQL query to filter data in PHP
$search_term = "apple";
$sql = "SELECT * FROM fruits WHERE name LIKE '%$search_term%'";
$result = mysqli_query($conn, $sql);
// Iterate over the results
while($row = mysqli_fetch_assoc($result)) {
echo $row['name'] . "<br>";
}
