Description
As of #34449 when using Yaml::DUMP_MULTI_LINE_LITERAL_BLOCK any multiline string with CRLF new lines will be encoded as a single line quoted string instead of a scalar block.
How to reproduce
Try to dump a string with CRLF new lines.
e.g.
$strings = [
"lf" => "multi\nline\nstring",
"crlf" => "multi\r\nline\r\nstring",
"mixed" => "multi\r\nline\nstring",
];
$yaml = Yaml::dump($strings, 2, 2, Yaml::DUMP_MULTI_LINE_LITERAL_BLOCK);
print($yaml);produces:
lf: |
multi
line
string
crlf: "multi\r\nline\r\nstring"
mixed: "multi\r\nline\nstring"Possible Solution
Change explode back to preg_split, but I'm unsure it explode was used for a specific reason.
