Saliyane fitur anyar kayata hinting jinis kanggo jinis data skalar utawa kinerja sing dioptimalake , PHP 7 uga nggawa ekstensi basa sing migunani lan anyar. "Operator Spaceship" pungkasane mlebu ing jagad PHP (Programmer Ruby lan Perl wis ngerti suwene). \($a <=> $b\) ngasilake \(0\) yen lan mung yen kalorone operan padha, \(1\) yen sisih kiwa luwih gedhe lan \(-1\) .
Manut, operator anyar iki cocog karo fungsi signum \(sgn(xy)\) dingerteni saka matématika. Iki tegese operator bandhing sing ana uga bisa ditafsirake nganggo sintaks anyar:
| \($a < $b\) | \(($a <=> $b) === -1\) |
| \($a <= $b\) | \(($a <=> $b)\) !\(== 1\) |
| \($a == $b\) | \(($a <=> $b) === 0\) |
| \($a\) !\(= $b\) | \(($a <=> $b)\) !\(== 0\) |
| \($a >= $b\) | \(($a <=> $b)\) !\(== -1\) |
| \($a > $b\) | \(($a <=> $b) === 1\) |
Aturan sing padha ditrapake kanggo operator perbandingan (contone \([1,2,3] <=>[1,2,1]\) \(1\) ).
