The Garmin navigation device uses the GNOME interface (figure)-General Linux technology-Linux technology and application information. For more information, see the following. Garmin is a famous navigator manufacturer. They released two latest Linux-based source code models, Nuvi 8xx and 5xx. among them, 8xx series are 4.3 inch products, resolution up to 480x272, using the Marvell PXA-3xx processor, Gnome Mo

What is the difference between static and common global variables in PHP? Lt ;? Phpfor ($ i1; $ I lt; 5; $ I ++) { nbsp; $ glo1; nbsp; static $ glo1; nbsp; $ glo ++ ;} echo $ glo ;? Gt; in the preceding example, $ glo is globally scoped, and the output result is different from the output result without the static keyword, it turns out that PHP static global

The use of the shell to achieve Informix performance monitoring, and output in HTML format, intuitive and convenient. It is suitable for monitoring system performance when Informix system is first built. This example is designed according to the cron mechanism, which is scheduled to be monitored every day when the system is busy, in order to analyze and rationalize the resource allocation and parameter settings of the system. #!/bin/ksh#ScriptName: Getgloinfo#定义环境变量Informixdir=/usr/informixInfo

variables can also achieve the above purpose, global variables sometimes cause unexpected side effects, so it is best to use local static variables. The code is as follows:Function test (){Static $ var = 5; // static $ var = 1 + 1; an error is returned.$ Var ++;Echo $ var .'';} Test (); // 2Test (); // 3Test (); // 4Echo $ var; // error: Notice: Undefined variable: var Static global variables: The code is as follows:// Global variables are static storage, and all global variables are static va

Static local variables: 1. It will not change with the function call and exit. However, although the variable still exists, it cannot be used. If you call a function that defines it again, it can continue to be used and save the value left after the previous call.2. Static local variables will only be initialized once3. Static attributes can only be initialized as a character value or a constant, and expressions are not supported. Even if no initial value is assigned to a local static variable,

calls, you can consider using static local variables. Although global variables can also achieve the above purpose, global variables sometimes cause unexpected side effects, so it is best to use local static variables. The Code is as follows: Function test () { Static $ var = 5; // static $ var = 1 + 1; an error is returned. $ Var ++; Echo $ var .''; } Test (); // 2 Test (); // 3 Test (); // 4 Echo $ var; // error: Notice: Undefined variable: var Static global variables: The Code is as f

can also achieve the above purpose, global variables sometimes cause unexpected side effects, so it is best to use local static variables. The code is as follows: Function test (){Static $ var = 5; // static $ var = 1 + 1; an error is returned.$ Var ++;Echo $ var .'';} Test (); // 2Test (); // 3Test (); // 4Echo $ var; // error: Notice: Undefined variable: var Static global variables: The code is as follows: // Global variables are static storage, and all global variables are static variable

variable, it's going to be like this. This may not be able to appreciate the benefits of PHP, then we first assume that the reader is also familiar with JS, in JS is not static this keyword, so if we want to implement a program with the ability to save each time the results of the program as the basis of the next operation we need to write. var glo=0; function test () {glo++; Document.writeln (

. Although global variables can also achieve the above purpose, global variables sometimes cause unexpected side effects, so it is best to use local static variables. The code is as follows: Function test (){Static $ var = 5; // static $ var = 1 + 1; an error is returned.$ Var ++;Echo $ var .'';} Test (); // 2Test (); // 3Test (); // 4Echo $ var; // error: Notice: Undefined variable: var Static global variables: The code is as follows: // Global variables are static storage, and all global va

value 0 (for numeric variables) or null characters (for character variables). The initial value of the static variable is 0.4. when you call a function multiple times and require that the values of some variables be retained between calls, you can consider using static local variables. Although global variables can also achieve the above purpose, global variables sometimes cause unexpected side effects, so it is best to use local static variables. // @ Link http://www.phpddt.comfunction test ()

What is the difference between a PHP static global variable and a normal global variable? In the above example, $glo is a global scope, and the output is different from the non-static keyword, it turns out that the use of static global variables can be used, but the PHP manual only talks about using static variables in functions, as well as static member properties and methods of classes. Does not involve the concept of static global variables,

variables. Although the above goal can be achieved with global variables, global variables sometimes cause unexpected side effects, so it is advisable to adopt local static variables. The code is as follows: function test () {Static $var = 5; static $var = 1+1; it will error $var + +; Echo $var. ' '; Test (); 2 test (); 3 Test (); 4 echo $var; Error: notice:undefined variable:var about static global variables: The code is as follows://The global variable itself is a static storage mode, all

only once 3. A static property can only be initialized to a character value or a constant and cannot be used with an expression. Even if the local static variable is defined without an initial value, the system automatically assigns the initial values of 0 (to numeric variables) or null characters (to character variables), and the static variable is initially 0. 4. Consider using static local variables when you call a function multiple times and require the values of certain variables to be pre

variables to be preserved between calls. Although this can be achieved with global variables, global variables sometimes cause unintended side effects, so it is advisable to use local static variables. function test () { static $var = 5; Static $var = +, will error $var + +; Echo $var. ' ';} Test (); 2test (); 3test (); 4echo $var; Error: notice:undefined Variable:var About static global variables: The global variable itself is the static storage mode, all global variables are static
