note 38973 deleted from functions by nlopess

Note Submitter: Diego Vilar, at Unimed Sergipe, Brazil ---- I came across the problem so discussed in this thread.. and after reading some people's sugestions and ideas, I found that using globals is the way. In my case, I had a function B inside another function A, and this function B needed access to variables defined inside A. But I wanted to reference those variables, inside both functions, as local variables, Thats how I solved in an elegant way, I think.. function Alpha() { function Beta() { // DEFINITIONS global $Apple, $Orange; // Do whatever u want with $Apple and $Orange ... } // DEFINITIONS $Banana = ""; $Apple = ""; $Orange = ""; // Export local variables needed outside $GLOBALS["Apple"] = &$Apple; $GLOBALS["Orange"] = &$Orange; // Do some stuff inside A with its variables $Apple = "red, juicy"; $Orange = "orange, also juicy"; Beta(); } Now, you realize that this is not new, but the center idea here is to separete a block inside the function to "export" whatever variables you need to give access to other functions, keeping its names, thus making the code more readable and organized. For those who need to call Alpha() more then once, it would be useful to encolse Beta() definition inside a condition that checks if it's already been declared, just like bellow: ... if (!function_exists("Beta")) { function Beta() { // DEFINITIONS global $Apple, $Orange; // Do whatever u want with $Apple and $Orange ... } } ... Now, for those who want a more professional solution, I'd sugest creating a function that registers local and global variables. That way, you could declare a variable by doing somthing like DefLocalGlobal("varname"), and the DefLocalGlobal() function would, using eval(), declare the local instance ($varname) and its global reference ($GLOBAL["varname"]). You could even write a function for garbage collect those variables just before leaving the caller function, so you would free memory when those variables would not be necessary anymore.
