PHP 8 Backwards Compatibility Library

Description

This package provides functions of newer PHP 8 versions.

It provides scripts that implement functions only available in newer PHP versions as functions built-in in the PHP core engine. The parts work in older PHP versions.

A main script checks the current PHP version and loads that implement the functions of newer PHP versions.

Error FILE [compat_error.php]

This file contains support code for the remaining functions of the phpbcl8 library.

A	PHP	phpbcl8	TYPE	NAME	DESCRIPTION
+	ALL	1.0.8	FILE	compat_error.php	To support errors

phpbcl8 FILE [phpbcl.php]

A	PHP	phpbcl8	TYPE	NAME	DESCRIPTION
+	ALL	1.0.5	FILE	phpbcl.php	To support other functions in this php library

DEPRECATED FILE [compat_deprecated.php]

The use of the contents of the deprecated-removed code file is the reverse of the use of other files versioning-based on the php version.

This means that from the PHP version that refers and to newer versions, without the use of phpbcl8 and specifically the file compat_deprecated.php, you will not be able to use this code.

A	PHP	phpbcl8	TYPE	NAME	DESCRIPTION
+	ALL	1.0.0	FILE	compat_deprecated.php	for deprecated-removed php functions
+	>= 8.1.0	1.0.0	CONST	ENT_COMPAT	ENT_QUOTES
+	>= 8.0.0	1.0.0	CONST	MB_OVERLOAD_MAIL	= 1
+	>= 8.0.0	1.0.0	CONST	MB_OVERLOAD_STRING	= 2
+	>= 8.0.0	1.0.0	CONST	MB_OVERLOAD_REGEX	= 4
+	>= 8.0.0	1.0.0	Function	each	Return the current key and value pair from an array and advance the array cursor.

VERSIONING FILES [compat_php81x.php - compat_php85x.php]

The contents of version-based files mean that since added to a specific PHP version, without using phpbcl8, you will not be able to use them in older versions.
