Hi,
I've already posted this patch and it has since been reviewed and
improved.
I'm re-posting it for discussion before eventually commiting it.
The ternary operator always copies its second or third operand, which
is very
slow compared to an if/else when the operand is an array for example:
...
Same "copy always" behavior is made with string in ternary operator, and
it can be
also very annoying e.g:
$content =
file_get_contents('http://www.w3.org/TR/2011/WD-html-markup-20110525/spec.html');
$test = $content !== false ? $content : '';
Is it the same with: $content = file_get_contents('…') ?: ''; Maybe we
could have a heuristic for this shortcut operator no?
Best regards.
