An error is an undesirable programming outcome. The mistake is a subset of the error. Error management is a vital component of any website or programme.

Error handling is a mechanism for identifying errors that a programme makes and taking appropriate corrective action. This can be done by utilising die() method.

When a programming problem occurs, the software will halt further code execution and display the appropriate error message to the user. The die() function displays a message and terminates the running of the programme.

The connect() function in PHP is one that is used to establish a connection to a database.

The end() method in PHP is used to locate the final element of the specified array. The end() function updates an array's internal pointer to refer to the final element and returns that element's value.

The isset() function examines whether a variable is set, which implies that it has to be declared and is not NULL. If the variable is present and not NULL, this function will return true; otherwise, it will return false.
