Judging teacher PHP Devil special Training Note (10)

　　In order to prevent the code to confuse us, we look at the video of the separation method 1, a new folder called Code (this means Code) 2, and then create a new folder called Page (this is the Page)

How do you write the code? Here to remember the formula 1, index.php is always "the main manager." Always load code and page 2, code inside the file can only write PHP code 3, page inside the file, in principle to write html, but can embed some PHP code. Please see the video operation for Details.

　　For some reason, we stipulate that any file that writes a variable must be var.php as a file suffix such as code1.var.php. Then we often need to write a "code final compiler" (idea Extension) we go back to our God program, the design requirements are as follows 1, the receiving parameter "compile" 2, the parameter implementation of the code folder inside the xxx.var.php form of the file read out, for Processing.

1, we write a compile method in the God_frame

    functionCompile () {//read the duplicate variables in code to get rid of them .       $_files=Scandir($thisProject_folder. ' /code '); foreach($_files  as $_file){           if(Preg_match("/\w+\.var\.php$/i",$_file)){               require($this->project_folder. ' /code/'.$_file); unset($_file); }       }        unset($_files);//destroy this invalid Variable//var_export (get_defined_vars ());        $result= ' <?php '.Php_eol.‘ Ectract ('.Var_export(Get_defined_vars(), 1). '); '; file_put_contents($this->project_folder. " /vars.php ",$result);//}

This method is called in Godinit:

    Static function compile () {        $get _config = loadconfig ();         $GF new god_frame ($get _config-prj_name);         $gf  -compile ();    }

So we can see that in our custom folder, a vars.php file is generated

Knowledge Points:

The Scandir function, which lists the files and directories in the specified path (returns an Array)

Var_export ();

Regular matching function (simple Use) preg_match (regular expression, to match the content); True if match to return

Get_defined_vars (); Returns an array of all defined Variables.

Unset: destroys the specified variable;
