I have been playing with php for a while. It basically started with from & nbsp; 0 and often encountered many problems. I am able to query documents more skillfully. besides, I have less experience. & Nbsp; look & nbsp; here. : & Nbsp; error_reporting (1048); //, S has been playing php for a while, basically starting from 0, and there are also many problems that often occur, you can easily query documents and have less experience.
Look here first. :
Error_reporting (1048); // 1048 ,...,
Ob_start ();
Session_start ();
Date_default_timezone_set (Asia/Shanghai );
Php passes the call to consume a lot of memory.
Generally, do not use define too much.
5 has done a lot of work in the construction of classes and attribute machines, so we won't talk about the bugs to overcome. __series functions all have some highlights and support
Static.
According to my existing programs, framework pages are rarely used. I feel that the speed in php is not a problem.
Pay attention to the calling sequence of classes, especially those that have extends, and release the memory accurately.
@ Mysql_fetch_array ($ result, MYSQL_ASSOC); note that the usage of MYSQL_ASSOC, MYSQL_NUM, and MYSQL_BOTH is an enum. The default value is
MYSQL_BOTH.
Mysql statement. if in is executed, limit is no longer supported. So... very troublesome.
Supports distinct, group, program execution, and md.
If (get_magic_quotes_gpc ()){

/**
* Errors in the processing program
* @ Date: 2006-10-9-
* @ Param (type) (parameter name) (description)
*/
Function Error_Handler ($ errno, $ errstr, $ errorfile, $ errline, $ errtext ){
Echo (system error:. $ errstr );
Echo (At. $ errorfile. the. $ errline. line .);
If ($ errno = E_USER_ERROR ){
Echo (fatal error, the program has been aborted );
}
}
Set_error_handler (Error_Handler );
Trigger_error (call trigger_error, E_USER_ERROR );
This is obtained using the function. of course, your error report level should be high:
Error_reporting (1048 );
To be more oo, let's first look at a self-written function that describes the class:
$ Classname = Exception;
/**
* (Function description)
* @ Date:
* @ Param (type) (parameter name) (description)
*/
Function ClassDetail ($ classname ){
If (! Class_exists ($ classname )){
Echo ($ classname. the class does not exist );
} Else {
Print_r ("The following description class". $ classname );
Print_r ("all methods
");
print_r(get_class_methods($classname));
print_r("
");
Print_r (" All attributes
");
print_r(get_class_vars($classname));
print_r("
");
}
}
ClassDetail ($ classname );
It is found that all the get methods of the exception class are:
[0] => _ construct
[1] => getMessage
[2] => getCode
[3] => getFile
[4] => getLine
[5] => getTrace
[6] => getTraceAsString
[7] => _ toString
You can also slowly optimize your personality.
OK, let's look at the oo processing method:
Class ErrorHandlers extends Exception {
Private $ _ context = null;
Function _ construct ($ level, $ string, $ file, $ line, $ context = null ){
Parent: :__ construct ($ string, $ level );
$ This-> file = $ file;
$ This-> line = $ line;
$ This-> _ level = $ level;
$ This-> _ context = $ context;
}
Function _ destruct (){
// Parent ::__ destruct ();
}
Function Message (){
$ Errors = array (
E_ERROR => error,
E_WARNING => warning,
E_PARSE => parsing error,
E_NOTICE => notice,
E_CORE_ERROR => core error,
E_CORE_WARNING => core warning,
E_COMPILE_ERROR => compile error,
E_COMPILE_WARNING => compile warning,
