Will added soon ...

About

This simple php interpreter written in c++11 and can be used as template engine in c++ too.

Porpus

My porpus is converting php code too c++ and compile it at the end

OOP

You can write c++ class and call it in 4php

See extension directory

class test : var {
private:
	int z = 10;
public:
	test() {
		std::cout << "construced" << std::endl;
	}

    var pejmanhkh( var &p ) {
    	print_r( p );
    	std::cout << "z is " << z << std::endl;
    	z = 4;
    	return 0;
    }

    var ppp( var &p ) {
    	std::cout << "z is " << z << std::endl;
    	return 0;
    }

    ~test() {
    	std::cout << "destructed" << std::endl;
    }
};

Usage :

<?4php

$a = new test();

print_r( $a );

$a->pejmanhkh( "test", 1, 2 );

echo("dadsas\n");

$a->ppp( "test" );


echo("dadsas\n");

$aa = new test();
$aa->pejmanhkh( "test", 1, 2 );


?>

Writing Extension

writing extension in c++ is very easy

Example :

var exten_implode( var &p )  {
    var out = "";
    var pre = "";
    for( auto x : p[1] ) {
        out += pre+p[1][x];
        pre = p[0];
    }

    return out;
}

And add it to functions :

Building

Before compile main.cpp you sould make every extension by hand in extension directory

g++ -std=c++11 main.cpp  -o 4php -ldl

Usage

./4php test.php

Web programming

You can use 4php in cgi with shebang

Request function make web request array & you can set superglobal functions with $SUPERGLOBALS variable and use it in function scope too.

#!4php
<?
echo("Content-type: text/html\r\n\r\n");

$request = request();

//define superglobal variable in 4php
$SUPERGLOBALS['_GET'] = $request['get'];
$SUPERGLOBALS['_POST'] = $request['post'];
$SUPERGLOBALS['_SERVER'] = $request['server'];
print_r( $_SERVER );

function test() {
	print_r( $_SERVER );
}

test();
?>

Update

1. Constant added
2. Globalize in function added
3. Include support added
4. Eval support added
5. Define superglobal variable
6. Web programming added ( cgi with shebang )
7. Not showing shebang added
8. Update variable set and add .= and += & ... operator
