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?
