Why Does My PHP Script Throw a 'Call to Member Function execute() on Boolean' Error?

Call to Member Function execute() on Boolean: Debugging mysqli Query Execution

When attempting to execute a prepared statement in a PHP script, a fatal error may arise if the prepare method returns a boolean value (either TRUE or FALSE) instead of a mysqli_stmt object. This can be traced back to an error in the query string or a syntax issue within the prepare statement.

One potential cause for this error is a typo in the INSERT statement. In the provided code snippet, the typo 'INSET' (line 18) should be corrected to 'INSERT.' Failure to use the correct syntax will result in the prepare method returning FALSE and triggering the error.

To resolve this issue, ensure that the query string is written correctly and follows the correct syntax for the intended database operation. Specifically, double-check that the command being executed is 'INSERT.' By rectifying any syntax errors, you can ensure that the prepare method returns a mysqli_stmt object, allowing the execute method to function properly and successfully execute the prepared statement.
