have been playing PHP for some time, the basic is from 0 start, often appear a lot of problems, slowly can be proficient in querying documents, and, experience is not a lot.
Look at here first. ：
Error_reporting (1048);//1,2,4,7,...,1048
Ob_start ();
Session_Start ();
Date_default_timezone_set (Asia/shanghai);
PHP's recursive calls consume a lot of memory.
Generally, do not use define too much.
In the construction and property of the class, 5 has done a lot of work, to overcome the bug is not said, __ series of functions are some aspects, but also support
StaticOf
According to the program I have written now, rarely use the framework page, I feel that the speed in PHP is not a problem.
Note the order in which classes are called, especially those that have been extends, to release memory accurately.
@mysql_fetch_array ($result, MYSQL_ASSOC); This note uses chaos, Mysql_assoc,mysql_num and Mysql_both are an enum. The default is
Mysql_both.
The MySQL statement, if executed in, no longer supports limit. So ... Very troublesome.
Support Distinct,group, program loop execution, Md.
if (GET_MAGIC_QUOTES_GPC ()) {
$_get= STRIPSLASHES_GPC ($_get);
$_post= STRIPSLASHES_GPC ($_post);
$_cookie= STRIPSLASHES_GPC ($_cookie);
}
Set_magic_quotes_runtime (0); #magic_quotes_runtime
function STRIPSLASHES_GPC ($array) {
while (list ($key, $value) = each ($array)) {
if (is_string ($value)) {
$array [$key] = Addslashes (stripslashes ($value));
} else if (Is_array ($value)) {
$array [$key] = STRIPSLASHES_GPC ($value);
}
}
return $array;
}
/**
* Errors that occur in the handler
* @Date: 2006-10-9-10:51
* @param (type) (parameter name) (description)
*/
function Error_Handler ($errno, $errstr, $errorfile, $errline, $errtext) {
Echo (the system has an error:. $errstr);
Echo (at. $errorfile. $errline. Line.);
if ($errno ==e_user_error) {
Echo (fatal error, program aborted);
}
}
At the time of Use: Set_error_handler (Error_Handler);
Trigger_error (call trigger_error,e_user_error);
This is obtained using a function, and of course your error reporting level should be high:
Error_reporting (1048);
To be more oo, first look at a self-writing function that describes the class:
$classname =exception;
/**
* (function description)
* @Date:
* @param (type) (parameter name) (description)
*/
function Classdetail ($classname) {
if (!class_exists ($classname)) {
Echo ($classname. Class does not exist);
}else{
Print_r ("description class below". $classname);
Print_r ("All Methods
");
Print_r (Get_class_methods ($classname));
Print_r ("
");
Print_r (" All the properties
");
Print_r (Get_class_vars ($classname));
Print_r ("
");
}
}
Classdetail ($classname);
All get methods found for the exception class are:
[0] = __construct
[1] = GetMessage
[2] = GetCode
[3] = GetFile
[4] = GetLine
[5] = Gettrace
[6] = gettraceasstring
[7] = __tostring
Slowly optimize the personality point, also can.
OK, look at the comparison of OO processing methods:
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,
