PHP Backwards Compatibility Library (phpBCL)

Description

This package provides functions of newer PHP versions for older 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 phpBCL library.

| A | PHP | phpBCL | TYPE | NAME | DESCRIPTION |---|-----------|--------|-----------|-------------------------|----------------------------------------- | + | ALL | 1.0.8 | FILE | compat_error.php | To support errors for php < 7 | + | < 7.2.0 | 1.0.8 | Class | Error | | + | < 7.2.0 | 1.0.8 | Class | TypeError | | + | < 8.0.0 | 1.0.8 | Class | ValueError |

phpBCL FILE [phpBCL.php]

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

| A | PHP | phpBCL | TYPE | NAME | DESCRIPTION |---|-----------|--------|-----------|-------------------------|----------------------------------------- | + | ALL | 1.0.5 | FILE | phpBCL.php | To support other functions in this php library | + | >= 5.3.0 | 1.0.5 | Function | validate_encoding | Checks for any errors in the user's string encoding. | + | >= 5.3.0 | 1.0.7 | Function | alf_preg_quote | Quote regular expression characters.

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 phpBCL and specifically the file compat_deprecated.php, you will not be able to use this code.

| A | PHP | phpBCL | 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_php43x.php - compat_php85x.php]

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