/** |
|
5
|
|
|
* Return a CommandResult as the result of a command to pass both an exit |
|
6
|
|
|
* code and result data from a command. |
|
7
|
|
|
* |
|
8
|
|
|
* Usage: |
|
9
|
|
|
* |
|
10
|
|
|
* return CommandResult::dataWithExitCode(new RowsOfFields($rows), 1); |
|
11
|
|
|
* |
|
12
|
|
|
* The CommandResult can also be used to unambiguously return just |
|
13
|
|
|
* an exit code or just output data. |
|
14
|
|
|
* |
|
15
|
|
|
* Exit code only: |
|
16
|
|
|
* |
|
17
|
|
|
* return CommandResult::dataWithExitCode(1); |
|
18
|
|
|
* |
|
19
|
|
|
* Data only: |
|
20
|
|
|
* |
|
21
|
|
|
* return CommandResult::data(new RowsOfFields($rows)); |
|
22
|
|
|
* |
|
23
|
|
|
* Historically, it has always been possible to return an integer to indicate |
|
24
|
|
|
* that the result is an exit code, and other return types (typically array |
|
25
|
|
|
* / ArrayObjects) indicating actual data with an implicit exit code of 0. |
|
26
|
|
|
* Using a CommandResult is preferred, though, as it allows the result of the |
|
27
|
|
|
* function to be unambiguously specified without type-based interpretation. |

This check marks access to variables or properties that have not been declared yet. While PHP has no explicit notion of declaring a variable, accessing it before a value is assigned to it is most likely a bug.
