YAML DUMP_MULTI_LINE_LITERAL_BLOCK question, possible bug #20706
Description
In outputting an array to YAML, my multi-line strings were not being output as literals, but I found that if I changed the line in Dumper.php from
if ($inline > 1 && Yaml::DUMP_MULTI_LINE_LITERAL_BLOCK
& $flags && is_string($value) && false !== strpos($value, "\n")) {to
if ($inline >= 1 && Yaml::DUMP_MULTI_LINE_LITERAL_BLOCK
& $flags && is_string($value) && false !== strpos($value, "\n")) {then it works perfectly.
Is there a reason for checking for $inline > 1?
