Why Am I Getting the 'Call to a Member Function bind_param() on a non-object' Error in PHP?

Error Encountered: "Call to a Member Function bind_param() on a non-Object"

When attempting to utilize the bind_param() function within a prepared statement, users may encounter the error "Call to a member function bind_param() on a non-object." This error signifies that the statement's preparation has failed.

One potential culprit for this error is an invalid SQL statement provided to the prepare() function. If the table name or field(s) referenced in the query do not exist within the database, the preparation will fail, and prepare() will return false.

For instance, if you attempt to prepare a statement that selects from a non-existent table:

$qSelect = $DBH->prepare("SELECT * FROM non_existent_table WHERE username = ?");

This statement will fail to prepare, as the table "non_existent_table" does not exist. Subsequently, any attempt to bind parameters to the failed statement will result in the "Call to a member function bind_param() on a non-object" error.
