/**
 * This contains descriptions used by Phan for hover text of internal constants (global and class constants) in the language server mode.
 *
 * Format
 *
 * '<constant_name>' => 'documentation',
 *
 * NOTE: This format will very likely change as information is added and should not be used directly.
 *
 * Sources of function/method summary info:
 *
 * 1. docs.php.net's SVN repo or website, and examples (See internal/internalsignatures.php)
 *
 *    See https://secure.php.net/manual/en/copyright.php

 * 2. Various websites documenting individual extensions (e.g. php-ast)

 * CONTRIBUTING:
 *
 * Running `internal/internalstubs.php` can be used to update signature maps
 *
 * There are no plans for these signatures to diverge from what the above upstream sources contain.
 *
 * - If the descriptions cause Phan to crash, bug reports are welcome
 * - If Phan improperly extracted text from a summary (and this affects multiple signatures), patches fixing the extraction will be accepted.
 * - Otherwise, fixes for typos/grammar/inaccuracies in the summary will only be accepted once they are contributed upstream and can be regenerated (e.g. to the svn repo for docs.php.net).
 *
 *   Note that the summaries are used in a wide variety of contexts, and what makes sense for Phan may not make sense for those projects, and vice versa.

 (c) Use FAILED_PRECONDITION if the client should not retry until
     the system state has been explicitly fixed.  E.g., if an "rmdir"
     fails because the directory is non-empty, FAILED_PRECONDITION
     should be returned since the client should not retry unless
     they have first fixed up the directory by deleting files from it.
 (d) Use FAILED_PRECONDITION if the client performs conditional

> **A note on the compression strategy:**
>
> The strategy parameter is used to tune the compression algorithm.
>
> Use the value DEFAULT_STRATEGY for normal data, FILTERED for data produced by a filter (or predictor), HUFFMAN_ONLY to force Huffman encoding only (no string match), or RLE to limit match distances to one (run-length encoding).
>
> Filtered data consists mostly of small values with a somewhat random distribution. In this case, the compression algorithm is tuned to compress them better. The effect of FILTERED is to force more Huffman coding and less string matching; it is somewhat intermediate between DEFAULT_STRATEGY and HUFFMAN_ONLY.
>
> RLE is designed to be almost as fast as HUFFMAN_ONLY, but give better compression for PNG image data.
>
> FIXED prevents the use of dynamic Huffman codes, allowing for a simpler decoder for special applications.
>
> The strategy parameter only affects the compression ratio but not the correctness of the compressed output even if it is not set appropriately.

This will always result in a hash using the "$2y$" crypt format, which is always 60 characters wide.

Supported Options:

`salt` (`string`) - to manually provide a salt to use when hashing the password. Note that this will override and prevent a salt from being automatically generated. If omitted, a random salt will be generated by `password_hash` for each password hashed. This is the intended mode of operation and as of PHP 7.0.0 the salt option has been deprecated. `cost` (`integer`) - which denotes the algorithmic cost that should be used. Examples of these values can be found on the `crypt` page. If omitted, a default value of `10` will be used. This is a good baseline cost, but you may want to consider increasing it depending on your hardware.',

It is worth noting that over time this constant can (and likely will) change. Therefore you should be aware that the length of the resulting hash can change. Therefore, if you use `PASSWORD_DEFAULT` you should store the resulting hash in a way that can store more than 60 characters (255 is the recommended width).
