Setup 'php_dbg' [http://dd.cron.ru/dbg/] module on your php.ini 9 2. Run DBG Listener 10 3. Include this file at the end of you script 11 4. To enable profiling use you script with parameters: ?DBGSESSID=1@clienthost:7869;p=1 12 P.S.: see parameters bellow 13 5. To disable profiling use you script with parameters: ?DBGSESSID=-1 14 15 P.S. All DBGSESSID parameters stored in cookie. You must run in once to enable, and 16 once to disable. 17 18 19 ***************************************************************************** 20 DBGSESSID Usage: 21 ***************************************************************************** 22 23 DBGSESSID=nnn[@host][:port][;{flags}] 24 25 where 26 27 nnn - is session ID (any positive number or zero) 28 NOTE: negative values prohibit debug session to run and drops cookie 29 30 host - is host name or IP address of the host where your run PHPED IDE. 31 You may set clienthost which is a keyword, in this case debugger looks for 32 proper client IP address automatically. 33 34 flags - set of the following flags delimited with commas: 35 s=skip - skip number of HTTP requests before actual session should run 36 d={0|1} - start debug session 37 p={0|1} - start profiler session 38 39 For example: 40 DBGSESSID=1@clienthost:7869;d=1,p=1 41 DBGSESSID=1;d=1,p=0 42 DBGSESSID=1:7869;d=1,p=0,s=5 43 44On/Off: 45 javascript: document.cookie = 'DBGSESSID=' + escape('1;d=1,p=0') + '; path=/'; document.execCommand('refresh'); 46 javascript: document.cookie = 'DBGSESSID=' + escape('1;d=0,p=0') + '; path=/'; document.execCommand('refresh'); 47 48 javascript:location.href=location.protocol+'//'+location.hostname+location.pathname+'?DBGSESSID=1;d=1,p=0' 49 javascript:location.href=location.protocol+'//'+location.hostname+location.pathname+'?DBGSESSID=-1 50 51 ***************************************************************************** 52 PHP_DBG Module functions 53 ***************************************************************************** 54 55 56 --------------------------------------------------- 57 get all profiler results 58 --------------------------------------------------- 59 int dbg_get_profiler_results(array &$results); 60 61 return int: count of $results 62 63 $results = array( 64 'mod_no' => array(), 65 'line_no' => array(), 66 'hit_count' => array(), 67 'tm_max' => array(), 68 'tm_min' => array(), 69 'tm_sum' => array(), 70 ); 71 72 73 --------------------------------------------------- 74 get all modules name 75 --------------------------------------------------- 76 int dbg_get_all_module_names(array &$results); 77 78 return int: count of $results 79 80 $results = array( 81 'mod_no' => array(), 82 'mod_name' => array(), 83 ); 84 85 86 --------------------------------------------------- 87 get module name 88 --------------------------------------------------- 89 int dbg_get_module_name(int $mod_no, string &$results); 90 91 return int: 0 - error 92 1 - success 93 94 $results = module name 95 96 97 --------------------------------------------------- 98 get all context (function name) for given module 99 --------------------------------------------------- 100 int dbg_get_all_contexts(int $mod_no, array &$results); 101 102 if $mod_no = 0 it returns all contexts 103 104 return int: count of $results 105 106 $results = array( 107 'ctx_no' => array(), 108 'mod_no' => array(), 109 'ctx_name' => array(), 110 ); 111 112 113 --------------------------------------------------- 114 get context name 115 --------------------------------------------------- 116 int dbg_get_context_name(int $ctx_no, string &$function_name); 117 118 return int: 0 - error 119 1 - success 120 121 $function_name = function name 122 123 124 --------------------------------------------------- 125 get all source lines for given module 126 --------------------------------------------------- 127 int dbg_get_all_source_lines(int $mod_no, array &$results); 128 129 if $mod_no = 0 it returns all source lines for all contexts 130 131 return int: count of $results 132 133 $results = array( 134 'ctx_no' => array(), 135 'mod_no' => array(), 136 'line_no' => array(), 137 ); 138 139 140 --------------------------------------------------- 141 get context id for given module and line 142 --------------------------------------------------- 143 int dbg_get_source_context(int $mod_no, int $line_no, int &$ctx_no); 144 145 return int: 0 - error 146 1 - success 147 148 $ctx_no = function name 149 150*/ 151 152############################################################################## 153 154class profiler_dbg extends profiler 155{ 156 var $min_time = 0; 157 var $total_time = 0; 158 159 // $min_time - ??????????? ????? ?????????? ??? ?????? ? ????????? ??????????? ??????????
