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]

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

| 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 | ENT_SUBSTITUTE | ENT_HTML401 | + | >= 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.
