What are some alternative methods to using FIND_IN_SET in MySQL for comparing values in PHP?
Using FIND_IN_SET in MySQL can be inefficient when comparing values in PHP, especially with large datasets. One alternative method is to fetch the data from the database and then compare the values in PHP using a loop or array functions. This allows for more flexibility and control over the comparison process.
// Fetch data from the database
$query = "SELECT * FROM table";
$result = mysqli_query($connection, $query);
// Compare values in PHP
while ($row = mysqli_fetch_assoc($result)) {
if (in_array($valueToCompare, explode(',', $row['column']))) {
// Value found, do something
}
}
