thinkphp Debug mode and Logging overview, thinkphp logging

This article is described as the use of thinkphp debug mode and logging, which plays a very important role in the development of thinkphp project, it is necessary to understand and grasp. Here's how:

1, can be set in config.php, the default is off state.

The opening method is as follows:

' App_debug '  = True

Open the \thinkphp\common\debug.php file to see the default settings for debug as follows:

Return Array (  ' Log_record ' =>true,//Logging  ' log_record_level '    = =  Array (' Emerg ', ' ALERT ', ' Crit ', ' ERR ', ' WARN ', ' notic ', ' INFO ', ' DEBUG ', ' SQL '),//allow logging of log levels  ' Db_fields_cache ' + false,//database field cache  ' Show_run_time ' =>true,     //Run time display  ' Show_adv_time ' =>true,     //show verbose run time  ' show_db_times ' = True,     //Display database query and write times  ' Show_cache_times ' =>true,    //Display cache operation Count  ' Show_use_mem ' =>true,      //Display memory overhead  ' Show_page_trace ' =>true,    //Display page trace information assigned by trace file definition and action action  ' app_file_case ' = >  True,//whether check file capitalization is valid for Windows platform);

Note: The Db_fields_cache database field cache is closed by default, if it is turned on, the file cache is generated under the Runtime\data folder, and after the table has been modified, such as the newly added field, this cache cannot record your operation, we need to delete it manually. Changes to the table will not succeed.

After the ' App_debug ' is true, the access page will appear as a DEBUG prompt:

If you want to display only a subset of the information, such as run time, memory overhead, etc.,

You can make the appropriate settings in config.php, such as:

' App_debug ' +  true,//debug mode switch ' Show_run_time ' + true,//Run time display ' show_adv_time ' = true,//show verbose run time ' show _db_times ' + true,//Display database operation Count ' Show_cache_times ' =>true,//Display cache operation count ' show_use_mem ' = true,//display memory overhead

Tip information such as:

2, the page trace information customization: \thinkphp\tpl\pagetrace.tpl.php

Custom method One: Add a trace.php file to the config.php's sibling directory with the following code:

<?php return array{  ' current SERVER information ' =>$_server[' REMOTE_ADDR '],};? >

Custom method Two: Add in the action method:

$this->trace (' Debug Test ', ' 5211314 ');

3, Output Debugging method:

Halt (' aaaaaaa ');//output AAAAAA and interrupt program execution

4. Model debugging: Displaying SQL statements

$User =new Model (' User '); $User->find (1); echo $User->getlastsql ();//output the last SQL statement executed

5. Log record \thinkphp\lib\think\core\log.class.php

Set in config.php

' Log_record ' =>true,//turns on logging ' Log_record_level ' =>array (' Emerg ', ' ALERT ', ' ERROR '),

I hope the method described in this article is helpful to everyone.

thinkphp where the log record file is found

Log record \thinkphp\lib\think\core\log.class.php

1, can be set in config.php, the default is off state. ' App_debug ' = True

Open the \thinkphp\common\debug.php file to see the default settings for debug as follows:

Return Array (

' Log_record ' =>true,//logging

' Log_record_level ' = = Array (' Emerg ', ' ALERT ', ' crit ', ' ERR ', ' WARN ', ' notic ', ' INFO ', ' DEBUG ', ' SQL '),//allow logging of log levels
' Db_fields_cache ' = false,//database field cache

' Show_run_time ' =>true,//Run time display
' Show_adv_time ' =>true,//show verbose run time
' Show_db_times ' =>true,//Display database query and write times
' Show_cache_times ' =>true,//display the number of cache operations
' Show_use_mem ' =>true,//display memory overhead
' Show_page_trace ' =>true,//Display page trace information is assigned by the trace file definition and action action
' App_file_case ' = true,//check if file capitalization is valid for Windows platform
);

Note: The Db_fields_cache database field cache is closed by default, if it is turned on, the file cache is generated under the Runtime\data folder, and after the table has been modified, such as the newly added field, this cache cannot record your operation, we need to delete it manually. Changes to the table will not succeed.

After the ' App_debug ' is true, the access page will appear as a DEBUG prompt:

If you want to display only a subset of the information, such as run time, memory overhead, etc.,

You can make the appropriate settings in config.php, such as:

' App_debug ' = = true,//debug mode switch
' Show_run_time ' + true,//Run time display
' Show_adv_time ' = true,//show verbose run time
' show_db_times ' = = true,//display number ... Remaining full text >>

thinkphp calling templates and debugging modes

Let me tell you the answer!
This is fine, you build a IndexAction.class.php file in the Admin/lib/action,
Display ();
}
}
Then build an index folder in the ADMIN/TPL, and build a index.html file in this folder.
