Generate php code for php program_PHP tutorial
A .php file, including the program start symbol (), and the specific code is placed between the start symbol and the end symbol. In order to facilitate future modification and program reading, it is customary that the code should be divided into lines according to certain regulations, and the variable marker ($) must be indispensable in the PHP code. These all bring some trouble to generating .php files, and some workarounds are needed to deal with them.
Let’s first deal with the start and end characters of the php program file. This is not too complicated. We use two variables to represent them:
$str_tmp="$str_end="?>"; //End character. $str_end is an independent variable.
Let’s deal with the variable marker ($). Assume that we will have such a variable equation in the generated .php file: $age="28";. The code is as follows:
$str="$"."age="28";rn";
In the above formula, printing the variable $str will get the expected effect. In the code, $ and age must be separated and combined with a connection sign (.) to get the effect of $age; the symbol (") indicates a small double quote ("); a line of PHP code must end with a semicolon (;); rn It means hitting Enter to start a new line.
Above we have solved the input problems such as PHP code start character, end character, code variable flag and equation, and now we can enter the specific operation of generating .php file. In order to make the program look like this, we preset the contents of the .php file to be generated: username (blackhorse), login password (blackhorse), age (28), and income (4500). The following is the complete code to generate the .php file:
//Collect information
$str_tmp="< ?phprn"; //Get the starting character of php. $str_tmp will be accumulated
$str_end="?>"; //php end character
$str_tmp.="$"."name="Dark Horse";rn"; //Add user name
$str_tmp.="$"."pass="blackhorse";rn"; //Join password
$str_tmp.="$"."age="28";rn"; //Join age
$str_tmp.="$"."income="4500";rn";
$str_tmp.=$str_end; //Add the terminator
//Save the file
$sf=" blhorse.php"; //File name
$fp=fopen($sf,"w"); //Open file in write mode
fwrite($fp,$str_tmp); //Save content
fclose($fp); //Close the file
?>
Save the above code as a file named test.php, run it, you will get the blhorse.php file, The complete content of the file is as follows:
$name="blackhorse";
$pass="blackhorse";
$age="28";
$income="4500";
?>
It can be seen that what we get is a fairly standard .php configuration class file, which fully meets our requirements. As for writing more complex .php files, as long as you handle the assignment of variables and the accumulation of variables as shown in the code in this article, it becomes quite easy to implement.

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
