The <function>error_reporting</function> function sets the
|
||||
<link linkend="ini.error-reporting">error_reporting</link>
|
||||
directive at runtime. PHP has many levels of errors, using
|
||||
this function sets that level for the duration (runtime) of
|

your script.

</para>
|

<para>
|

<function>error_reporting</function> sets PHP's error reporting level,
|
||||
and returns the old level. The <parameter>level</parameter> parameter
|
||||
takes on either a bitmask, or named constants. Using named constants
|
||||
is strongly encouraged to ensure compatibility for future versions. As
|
||||
error levels are added, the range of integers increases, so older
|
||||
integer-based error levels will not always behave as expected.

The user function needs to accept two parameters: the error code, and a
|
||||
string describing the error. From PHP 4.0.2, three optional
|
||||
parameters are supplied: the filename in which the error occurred, the
|
||||
line number in which the error occurred, and the context in which the
|
||||
error occurred (an array that points to the active symbol table at the
|
||||
point the error occurred). The function can be shown as:

Sets a user function (<parameter>error_handler</parameter>) to handle

errors in a script. Returns a string containing the previously defined

error handler (if any), or &false; on error. If the previous handler

This function can be used for defining your own way of handling errors

during runtime, for example in applications in which you need to do

cleanup of data/files when a critical error happens, or when you need

to trigger an error under certain conditions (using
