Line 145: Line 150:
  
 ==== strptime() ==== ==== strptime() ====
- 
-==== The procedural API of ext/fileinfo ==== 
- 
-It uses resources, while there is an OO API available. 
  
 ==== Passing a method name as the first parameter to ReflectionMethod::__construct() ==== ==== Passing a method name as the first parameter to ReflectionMethod::__construct() ====
  
 A ''ReflectionMethod::fromMethodName()'' method should be added as a replacement. A ''ReflectionMethod::fromMethodName()'' method should be added as a replacement.
 +
 +==== mhash*() function family ====
 +
 +''mhash*()'' functions were integrated into ext/hash in PHP 5.3 as a compatibility layer for ext/mhash (which has been removed in PHP 7.0), but they are hardly ever used, and very ill-behaved (primarily ''mhash()'').
 +
 +==== DatePeriod::__construct() ====
 +
 +This is a heavily overloaded function (it has 3 signatures) which should be deprecated in favour of 3 factory methods.
 +
 +==== ctype_*() function family accepts int parameters ====
 +
 +Although the documentation currently lists ''string'' as a valid parameter type for ''ctype_*'' functions, it's not the case. They also accept an integer which is only mentioned in a note:
 +
 +<blockquote>
 +If an integer between -128 and 255 inclusive is provided, it is interpreted as the ASCII value of a single character (negative values have 256 added in order to allow characters in the Extended ASCII range). Any other integer is interpreted as a string containing the decimal digits of the integer.
 +</blockquote>
 +
 +Moreover, if any other type than int or string is passed, ''ctype_*()'' functions silently return ''false''.
 +
 +Since the current behaviour is highly surprising, passing integer values to ''ctype_*()'' functions should be deprecated first, and ZPP should be modified to only accept strings in the next major version.
 +
 +==== Predefined variable $http_response_header ====
 +W.I.P.
 +See https://www.php.net/manual/en/reserved.variables.httpresponseheader.php
 +We already deprecated/removed $php_errormsg and $HTTP_RAW_POST_DATA
 +
 +==== Return by reference with void type ====
 +
 +''function &test(): void {}'' currently allows, probably shouldn't be?
 +
 +
 +==== NIL constant defined by the IMAP extension ====
 +The ''NIL'' constant corresponds to the value ''0'', and can be confused with ''null''.
 +
 +==== unserialize_callback_func INI setting ====
 +W.I.P. (but from my understanding this was used with __autoload() only - girgias)
