php convert string to method call

Answer 1

This feature is known as Variable functions, here is an example from php.net:

 \n";
 }

 function bar($arg = '')
 {
     echo "In bar(); argument was '$arg'.
\n";
 }

 // This is a wrapper function around echo
 function echoit($string)
 {
     echo $string;
 }

 $func = 'foo';
 $func();        // This calls foo()

 $func = 'bar';
 $func('test');  // This calls bar()

 $func = 'echoit';
 $func('test');  // This calls echoit()
 ?>
