Hi internals,
Voting has started today on https://wiki.php.net/rfc/readable_var_representation
and closes on 2021-02-19.
This RFC proposes introducing a new function `var_representation`
with the following differences from var_export:
1. `var_representation()` unconditionally returns a string
2. Use `null` instead of `NULL` - the former is recommended by more coding
guidelines (https://www.php-fig.org/psr/psr-2/).
3. Change the way indentation is done for arrays/objects.
See ext/standard/tests/general_functions/short_var_export1.phpt
(e.g. always add 2 spaces, never 3 in objects, and put the array start on the
same line as the key)
4. Render lists as `"[\n 'item1',\n]"` rather than `"array(\n 0 => 'item1',\n)"`
Always render empty lists on a single line, render multiline by default when there are 1 or more elements
5. Prepend `\` to class names so that generated code snippets can be used in
namespaces without any issues.
6. Support `VAR_REPRESENTATION_SINGLE_LINE` in $flags.
This will use a single-line representation for arrays/objects.
7. Escape control characters("\x00"-"\x1f" and "\x7f"(backspace)) inside of double quoted strings
instead of single quoted strings with unescaped control characters mixed with ` . "\0" . `.
Thanks,
-Tyson
