RE: [PHP] _SERVER variable insd prnt sttmnt

[Andrew Chase]

For the sake of legibility you could always assign the contents of
$_SERVER['PHP_SELF'] to another variable before using it in the print
statement:

$PHP_SELF = $_SERVER['PHP_SELF'];

print "";

Shouldn't be a problem security-wise as long as register_globals is off;
Even if somebody tried to pass an arbitrary value to PHP_SELF in the query
string, it would only show up in $_GET['PHP_SELF']. It also provides a quick
way to bring pre- 4.1.2 scripts relying on the old global $PHP_SELF up to
date.

This is the problem with not breaking out of a string to display a variable.
Ideally, you would do it this way:

print "";

But some people just have a problem with doing it that way, so you can use
braces.

print "";

If you don't use the braces, how is PHP supposed to know what you mean. Do
you mean to print a variable called $_SERVER, followed by a literal
['PHP_SELF'], or do you mean an array? How is PHP supposed to decide for
you? Like your second variable, $chars. Is that an array? Do you mean to
print out the value of an $chars element, or do you mean to print out value
of $char, followed by "[", value of $cnt, followed by "]" ??

Hope that helps.

Normally you would use:

  $_SERVER['PHP_SELF']

But inside a double-quoted string like above you would use:

  $_SERVER[PHP_SELF]
