The error_reporting() function sets the error_reporting directive at runtime. PHP has many levels of errors, using this function sets that level for the duration (runtime) of your script. If the optional level is not set, error_reporting() will just return the current error reporting level.
Open PH.ini file.
In this file search for the phrase “ error_reporting = E_ALL” ,[without inverted commas]
Here replace this with “error_reporting = E_ALL & ~E_NOTICE & ~E_WARNING “
(Show all errors, except for notices and coding standards warnings)
Make sure you change the real enabled part of this , there are certain other examples given in the file.
Restart your PHP + Apache
Now, no warnings and messages will appear in the browser.
Example #1 error_reporting() examples
// Turn off all error reporting
// Report simple running errors
error_reporting(E_ERROR | E_WARNING | E_PARSE);
// Reporting E_NOTICE can be good too (to report uninitialized
// variables or catch variable name misspellings …)
error_reporting(E_ERROR | E_WARNING | E_PARSE | E_NOTICE);
// Report all errors except E_NOTICE
error_reporting(E_ALL & ~E_NOTICE);
// Report all PHP errors (see changelog)
// Report all PHP errors
// Same as error_reporting(E_ALL);
The error_reporting() function specifies which errors are reported.
This function sets which errors are reported for the duration of the current script.
This funtion returns the old error_reporting level.
|report_level||Optional. Specifies the error report level for the current script. Value number and constant name are accepted, however, constant names are recommended for compatibility for future PHP versions|
|1||E_ERROR||Fatal run-time errors. Errors that can not be recovered from. Execution of the script is halted|
|2||E_WARNING||Non-fatal run-time errors. Execution of the script is not halted|
|4||E_PARSE||Compile-time parse errors. Parse errors should only be generated by the parser|
|8||E_NOTICE||Run-time notices. The script found something that might be an error, but could also happen when running a script normally|
|16||E_CORE_ERROR||Fatal errors at PHP startup. This is like an E_ERROR in the PHP core|
|32||E_CORE_WARNING||Non-fatal errors at PHP startup. This is like an E_WARNING in the PHP core|
|64||E_COMPILE_ERROR||Fatal compile-time errors. This is like an E_ERROR generated by the Zend Scripting Engine|
|128||E_COMPILE_WARNING||Non-fatal compile-time errors. This is like an E_WARNING generated by the Zend Scripting Engine|
|256||E_USER_ERROR||Fatal user-generated error. This is like an E_ERROR set by the programmer using the PHP function trigger_error()|
|512||E_USER_WARNING||Non-fatal user-generated warning. This is like an E_WARNING set by the programmer using the PHP function trigger_error()|
|1024||E_USER_NOTICE||User-generated notice. This is like an E_NOTICE set by the programmer using the PHP function trigger_error()|
|2048||E_STRICT||Run-time notices. PHP suggest changes to your code to help interoperability and compatibility of the code|
|4096||E_RECOVERABLE_ERROR||Catchable fatal error. This is like an E_ERROR but can be caught by a user defined handle (see also set_error_handler())|
All errors and warnings, except level E_STRICT (E_STRICT will be part of E_ALL as of PHP 6.0)
