sha1_smf

function sha1_smf(string $str): string

Define the old SMF sha1 function. Uses mhash if available

sha1_core

function sha1_core(string $x, int $len): string

This is the core SHA-1 calculation routine, used by sha1().

sha1_ft

function sha1_ft(int $t, int $b, int $c, int $d): int

Helper function for the core SHA-1 calculation

sha1_kt

function sha1_kt(int $t): int

Helper function for the core SHA-1 calculation

sha1_rol

function sha1_rol(int $num, int $cnt): int

Helper function for the core SHA-1 calculation

sha1_raw

function sha1_raw(string $text): string

Available since: (PHP 5) If the optional raw_output is set to TRUE, then the sha1 digest is instead returned in raw binary format with a length of 20, otherwise the returned value is a 40-character hexadecimal number.

smf_crc32

function smf_crc32(string $number): string

Compatibility function.

crc32 doesn’t work as expected on 64-bit functions - make our own. https://php.net/crc32#79567

mb_ord

function mb_ord(string $string, ?string $encoding = null): int|bool

Compatibility function.

This is a complete polyfill.

mb_chr

function mb_chr(int $codepoint, ?string $encoding = null): string|bool

Compatibility function.

This is a complete polyfill.

mb_ord_chr_encoding

function mb_ord_chr_encoding(string $encoding = null): string|bool

Helper function for the mb_ord and mb_chr polyfills.

Checks whether $encoding is a supported character encoding for the mb_ord and mb_chr functions. If $encoding is null, the current default character encoding is used. If the encoding is supported, it is returned as a string. If not, false is returned.

idn_to_ascii

function idn_to_ascii(string $domain, int $flags = 0, int $variant = 1, ?array &$idna_info = null): string|bool

Compatibility function.

This is not a complete polyfill:

• $flags only supports IDNA_DEFAULT, IDNA_NONTRANSITIONAL_TO_ASCII, and IDNA_USE_STD3_RULES.
• $variant is ignored, because INTL_IDNA_VARIANT_UTS46 is always used.
• $idna_info is ignored.

idn_to_utf8

function idn_to_utf8(string $domain, int $flags = 0, int $variant = 1, ?array &$idna_info = null): string|bool

Compatibility function.

This is not a complete polyfill:

• $flags only supports IDNA_DEFAULT, IDNA_NONTRANSITIONAL_TO_UNICODE, and IDNA_USE_STD3_RULES.
• $variant is ignored, because INTL_IDNA_VARIANT_UTS46 is always used.
• $idna_info is ignored.
