Something that has cropped up following migration to php5 and exception handling. Consider this
code:
<?php
/*** start code snippet ***/
try
{
bar(); // this call ok
foo(); // this call will fail
function foo() { return "foo"; }
foo(); // this call works now
}
catch (Exception $e)
{
// handle the exception
}
function bar() { return "bar"; }
/*** end snippet ***/
?>
My guess is that php reads all function definitions that are in the file scope of the script, but
any functions further down the scope list [eg block scope of the try block, or block scope of an if
statement (ie conditional functions mentioned above)] are ignored until they are reached by the
program flow.
