Deprecated Features
PHP Core
Case-Insensitive Constants
The declaration of case-insensitive constants has been deprecated. Passing
TRUE as the third argument to define() will now generate a
deprecation warning. The use of case-insensitive constants with a case that
differs from the declaration is also deprecated.
Namespaced assert()
Declaring a function called assert() inside a namespace is deprecated. The assert() function is subject to special handling by the engine, which may lead to inconsistent behavior when defining a namespaced function with the same name.
Searching Strings for non-string Needle
Passing a non-string needle to string search functions is deprecated. In the future the needle will be interpreted as a string instead of an ASCII codepoint. Depending on the intended behavior, you should either explicitly cast the needle to string or perform an explicit call to chr(). The following functions are affected:
Strip-Tags Streaming
The fgetss() function and the string.strip_tags stream filter have been deprecated. This also affects the SplFileObject::fgetss() method and gzgetss() function.
Data Filtering
The explicit usage of the constants
FILTER_FLAG_SCHEME_REQUIRED and
FILTER_FLAG_HOST_REQUIRED is now deprecated; both are
implied for FILTER_VALIDATE_URL anyway.
Internationalization Functions
Usage of the Normalizer::NONE form throws a deprecation
warning, if PHP is linked with ICU ≥ 56.
Multibyte String
The following undocumented mbereg_*() aliases have been deprecated. Use the corresponding mb_ereg_*() variants instead.
- mbregex_encoding()
- mbereg()
- mberegi()
- mbereg_replace()
- mberegi_replace()
- mbsplit()
- mbereg_match()
- mbereg_search()
- mbereg_search_pos()
- mbereg_search_regs()
- mbereg_search_init()
- mbereg_search_getregs()
- mbereg_search_getpos()
- mbereg_search_setpos()
ODBC and DB2 Functions (PDO_ODBC)
The pdo_odbc.db2_instance_name ini setting has been formally deprecated. It is deprecated in the documentation as of PHP 5.1.1.
