Operating system: solaris 2.7, linux 2.2.12
PHP version: 4.0 Release Candidate 1
PHP Bug Type: Misbehaving function
Bug description: function strcasecmp seams to order strings by their length
<html>
<Body>
<?
if(!$string2 || !$string2) {
echo "Please enter two strings to be compared by strcasecmp<br>
<form method=post>
<input type=text size=60 name=string1 value=\"$string1\"><br>
<input type=text size=60 name=string2 value=\"$string2\"><br>
<input type=submit value=\"go!\"></form>";
}
else {
if(strcasecmp($string1,$string2) < 1)
echo $string1."<br>is smaller than<br>".$string2;
else
echo $string2."<br>is smaller than<br>".$string1;
}
?>
</body>
</html>
The script returns for example "baaa" is smaller than "aaaaa".

; Language Options ;

engine = On ; Enable the PHP scripting language engine under Apache
short_open_tag = On ; allow the <? tag. otherwise, only <?php and <script> tags are recognized.
asp_tags = Off ; allow ASP-style <% %> tags
precision = 14 ; number of significant digits displayed in floating point numbers
y2k_compliance = Off ; whether to be year 2000 compliant (will cause problems with non y2k compliant browsers)
output_buffering = Off ; Output buffering allows you to send header lines (including cookies)
; even after you send body content, in the price of slowing PHP's
; output layer a bit.
; You can enable output buffering by in runtime by calling the output
; buffering functions, or enable output buffering for all files
; by setting this directive to On.
implicit_flush = Off ; Implicit flush tells PHP to tell the output layer to flush itself
; automatically after every output block. This is equivalent to
; calling the PHP function flush() after each and every call to print()
; or echo() and each and every HTML block.
; Turning this option on has serious performance implications, and
; is generally recommended for debugging purposes only.
allow_call_time_pass_reference = On ; whether to enable the ability to force arguments to be
; passed by reference at function-call time. This method
; is deprecated, and is likely to be unsupported in future
; versions of PHP/Zend. The encouraged method of specifying
; which arguments should be passed by reference is in the
; function declaration. You're encouraged to try and
; turn this option Off, and make sure your scripts work
; properly with it, to ensure they will work with future
; versions of the language (you will receive a warning
; each time you use this feature, and the argument will
; be passed by value instead of by reference).

; By default, users will only be able

; with PHP_ (e.g. PHP_FOO=BAR).
; Note: If this directive is empty, PHP
; will let the user modify ANY environment
; variable!
safe_mode_protected_env_vars = LD_LIBRARY_PATH ; This directive contains a comma-

; E_CORE_WARNING - warnings (non fatal errors) that occur during PHP's initial startup
