How to search for a comma-separated string in a database table in mySQL.

Suppose, I have a string in variable $facilities='breakfast,dinner,lunch' and in my database I have a string saved in a field called facilities having values breakfast,dinner,clothing,lunch,hot water.

    You're going to need to break apart the comma separated string first, and include a clause for each, so for that input you'd generate SQL like (assuming you want rows that have all three, and maybe other flags set):

    SELECT      *
    
    FROM        YourTable
    
    WHERE       FIND_IN_SET('breakfast', facilities)
        AND     FIND_IN_SET('dinner', facilities)
        AND     FIND_IN_SET('lunch', facilities)
    

    You can break the string apart in PHP with something a little like:

    $facilities='breakfast,dinner,lunch';
    $desired = explode ( "," , $facilities );
    

    And just use a loop to build your SQL

    SELECT  *
    FROM    tableName
    WHERE   FIND_IN_SET('lunch', 'breakfast,dinner,lunch')
    

    EDIT:

    SELECT * FROM tableName WHERE FIND_IN_SET('lunch', food_column)

    food_column is the name of the column where the string 'breakfast,dinner,lunch' is stored
