 1 | PHP 5.4 Short Arrays Converter []
 2 | =================================
 3 | 
 4 | Command-line script to convert between `array()` and PHP 5.4's short syntax `[]` (and vice versa).
 5 | 
 6 | It uses native PHP tokenizer, so conversion is safe.
 7 | The script was successfully tested against thousands of PHP files.
 8 | 
 9 | Usage
10 | -----
11 | 
12 | To convert all `*.php` and `*.phpt` files in whole directory recursively or to convert a single file use:
13 | 
14 | ```
15 | php convert.php <directory | file>
16 | ```
17 | 
18 | To convert source code from STDIN and print the output to STDOUT use:
19 | 
20 | ```
21 | php convert.php < input.php > output.php
22 | ```
23 | 
24 | To convert short syntax `[]` to older long syntax `array()` use option `--reverse`:
25 | 
26 | ```
27 | php convert.php --reverse <directory | file>
28 | ```
29 |
