note 81505 added to language.variables.scope

in reply to: "I hope some1 reading and understanding here creates an example about this. Im so lazy at doing that." -- pepesantillan at gmail dot com Though not exactly your example, I don't like functions declared within functions. So this is, effectively, the same result you were explaining :P <?php ini_set( 'display_errors', true ); error_reporting( E_ALL | E_STRICT ); /** * This is already in the global scope **/ $global_var1 = 'I\'m global!'; // Call a function some_function(); //Note that $localvar is NOT in the global scope //Undefined variable Error var_dump( $localvar ); function some_function() { /** * Now we are in function scope. Global scope vars can't be accessed here **/ // Undefined variable error (for $global_var1) $localvar = $global_var1; //Gonna call another function and send $localvar as ref another_function( $localvar ); // Note that $localvar has a value here... var_dump( $localvar ); } function another_function( &$input ) { // Get the global global $global_var1; // Assign it to $input which is referenced to $localvar in the other function $input = $global_var1; } ?> ---- Server IP: 209.41.74.194 Probable Submitter: 76.22.73.161 ---- Manual Page -- http://www.php.net/manual/en/language.variables.scope.php Edit -- https://master.php.net/note/edit/81505 Del: integrated -- https://master.php.net/note/delete/81505/integrated Del: useless -- https://master.php.net/note/delete/81505/useless Del: bad code -- https://master.php.net/note/delete/81505/bad+code Del: spam -- https://master.php.net/note/delete/81505/spam Del: non-english -- https://master.php.net/note/delete/81505/non-english Del: in docs -- https://master.php.net/note/delete/81505/in+docs Del: other reasons-- https://master.php.net/note/delete/81505 Reject -- https://master.php.net/note/reject/81505 Search -- https://master.php.net/manage/user-notes.php
