| 9 | * PHP errors:
|
|---|
| 10 | * E_ERROR ( integer ) Fatal run-time errors. These indicate errors that can not be recovered from, such as a memory allocation problem. Execution of the script is halted.
|
|---|
| 11 | * E_WARNING ( integer ) Run-time warnings (non-fatal errors). Execution of the script is not halted.
|
|---|
| 12 | * E_PARSE ( integer ) Compile-time parse errors. Parse errors should only be generated by the parser.
|
|---|
| 13 | * E_NOTICE ( integer ) Run-time notices. Indicate that the script encountered something that could indicate an error, but could also happen in the normal course of running a script.
|
|---|
| 14 | * E_CORE_ERROR ( integer ) Fatal errors that occur during PHP's initial startup. This is like an E_ERROR, except it is generated by the core of PHP. since PHP 4
|
|---|
| 15 | * E_CORE_WARNING ( integer ) Warnings (non-fatal errors) that occur during PHP's initial startup. This is like an E_WARNING, except it is generated by the core of PHP. since PHP 4
|
|---|
| 16 | * E_COMPILE_ERROR ( integer ) Fatal compile-time errors. This is like an E_ERROR, except it is generated by the Zend Scripting Engine. since PHP 4
|
|---|
| 17 | * E_COMPILE_WARNING ( integer ) Compile-time warnings (non-fatal errors). This is like an E_WARNING, except it is generated by the Zend Scripting Engine. since PHP 4
|
|---|
| 18 | * E_USER_ERROR ( integer ) User-generated error message. This is like an E_ERROR, except it is generated in PHP code by using the PHP function trigger_error(). since PHP 4
|
|---|
| 19 | * E_USER_WARNING ( integer ) User-generated warning message. This is like an E_WARNING, except it is generated in PHP code by using the PHP function trigger_error(). since PHP 4
|
|---|
| 20 | * E_USER_NOTICE ( integer ) User-generated notice message. This is like an E_NOTICE, except it is generated in PHP code by using the PHP function trigger_error(). since PHP 4
|
|---|
| 21 | * E_STRICT ( integer ) Enable to have PHP suggest changes to your code which will ensure the best interoperability and forward compatibility of your code. since PHP 5
|
|---|
| 22 | * E_RECOVERABLE_ERROR ( integer ) Catchable fatal error. It indicates that a probably dangerous error occured, but did not leave the Engine in an unstable state. If the error is not caught by a user defined handle (see also set_error_handler()), the application aborts as it was an E_ERROR. since PHP 5.2.0
|
|---|
| 23 | * E_ALL ( integer ) All errors and warnings, as supported, except of level E_STRICT in PHP < 6.
