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
+	>= 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_php84x.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.

+	< 8.4.0	1.1.1	Function	array_find	Returns the VALUE of the first element from $array for which the $callback returns true. Returns NULL if no matching element is found.
+	< 8.4.0	1.1.1	Function	array_find_key	Returns the KEY of the first element from $array for which the $callback returns TRUE. If no matching element is found the function returns NULL.

+	< 8.3.0	1.0.9	Function	stream_context_set_options	Sets options on the specified context.
+	< 8.3.0	1.0.0	Function	json_validate	Validate an string if contains a valid json.

While the function returns tokens either as a single-character string, or an array with a token ID, token text and line number, PhpToken::tokenize() normalizes all tokens into PhpToken objects, which makes code operating on tokens more memory efficient and readable.
