Message:

cCode:

void main(){

    printf("line1\n");

    printf("$var=2\n");

}

index.php

    exec("./cCode", $output); 

    echo $output[2];

?>

As you'd expect, the php outputs the string: $var=2

However, what is the simplest way of returning variables from C to become variables in php? Json encoding perhaps? Does php and/or C have any means to easily pass or convert variable name and value pairs?

Many thanks.

My Answer:
"Hello from C!\n");

// Passing variables to PHP
int num1 = 10;
int num2 = 20;
char str[] = "Hello from C!";

char command[100];
sprintf(command, "php -r '$_num1=%d; $_num2=%d; $_str=\"%s\"; include(\"script.php\");'", num1, num2, str);
system(command);
}
