How can the LIKE operator in SQL be used to search for specific values within serialized arrays in PHP?

When dealing with serialized arrays in PHP stored in a database, the LIKE operator in SQL can be used to search for specific values within these arrays. To do this, the serialized array needs to be converted into a string format that can be used in the SQL query. This can be achieved by using the PHP unserialize() function to convert the serialized array into a PHP array, then using the implode() function to convert the array into a string that can be used in the SQL query with the LIKE operator. 

// Assume $searchValue is the value we are searching for within the serialized array
$searchValue = 'value_to_search';

// Convert the serialized array from the database into a PHP array
$serializedArray = 'a:3:{i:0;s:5:"apple";i:1;s:6:"banana";i:2;s:5:"cherry";}';
$array = unserialize($serializedArray);

// Convert the PHP array into a string for SQL query
$arrayString = implode(',', $array);

// Use the LIKE operator in SQL to search for the specific value within the serialized array
$query = "SELECT * FROM table_name WHERE serialized_column LIKE '%$searchValue%'";
