Basic attributes (parameters)

Xdebug. default_enable

Type: boolean; default value: 1

This is the basic setting of xdebug. the error message is displayed by default during debugging tracking. You can use the xdebug_disable () function to disable debugging display for your code.

xdebug.halt_level=E_WARNING|E_NOTICE|E_USER_WARNING|E_USER_NOTICE

Xdebug. max_nesting_levelType: integer. default value: 256 (the default value for versions earlier than 2.3 is 100). This setting allows the maximum level of nested functions to run before the script stops. Xdebug. screamType: boolean. default value: 0. it starts with Xdebug version> = 2.1. if this value is set to 1, xdebug displays the notifications, warnings, and errors of the statements marked with the @ symbol, it is not hidden. Related functions: String xdebug_call_file ()Returns the name of the file where the function is currently executed. String xdebug_call_function ()Returns the name of the function source when the current function is called and executed. Int xdebug_call_line ()Returns the row number of the current execution. Example:

Example:
 // Called @ /home/httpd/html/test/xdebug_caller.php:12 from {main}

String xdebug_call_class ()Returns the name of the called class. Void xdebug_disable ()Error tracking information is not displayed. Void xdebug_enable ()Displays error tracking information. String xdebug_get_collected_errors ([int clean])Started with version 2.1. This function returns all error information collected in tabular format. The start point for collecting error information, which is determined by the xdebug_start_error_collection () function. By default, this function does not clear the error information collection cache. you can set the parameter to true to clear the cache. Array xdebug_get_headers ()Returns all header information in an array. all header information set by the header () function is returned.

 /**Returns:array(2) {  [0]=>  string(6) "X-Test"  [1]=>  string(33) "Set-Cookie: TestCookie=test-value"}*/

Bool xdebug_is_enabled ()Check whether the debugging trace is valid. Int xdebug_memory_usage ()Returns the memory usage of the script. The -- enable-memory-limit parameter must be included in the version compiled before PHP5.2.1, which is always valid in later versions. Int xdebug_peak_memory_usage ()Returns the maximum memory usage value. The -- enable-memory-limit parameter must be included in the version compiled before PHP5.2.1, which is always valid in later versions. Void xdebug_start_error_collection ()Started with version 2.1. when this function is executed, PHP will no longer display any notification warning or error information. This information will be stored in a cache and will be stopped unless it is executed to xdebug_stop_error_collection. The error information in the cache can be obtained through the xdebug_get_collected_errors () function. Void xdebug_stop_error_collection ()It starts with version 2.1 and is opposite to xdebug_start_error_collection () and stops collecting all notifications, warnings, and error messages. Note that it does not clear the cache for collection errors. Float xdebug_time_index ()Returns the current time index, that is, the number of seconds after the script starts running, expressed as a floating point.
