# I-PHP 7 kunye noMsebenzi weSpacehip1215

Ukongeza kwiimpawu ezintsha ezinje ngohlobo lokuthintela iintlobo zeedatha zesikali okanye ukusebenza okuphuculweyo , i-PHP 7 ikwazisa ulwandiso olutsha olunoluncedo. "Umsebenzi weSpacehip" ekugqibeleni uye wayenza kwilizwe le-PHP (Inkqubo kaRuby kunye nePerl beyazi ixesha elide). \(\$a <=> \$b\) ubuya \(0\) ukuba kwaye kuphela ukuba zombini ii-opharetha ziyalingana, \(1\) ukuba ekhohlo inkulu kwaye \(-1\) ngenye indlela.

Ngokuhambelana, lo mqhubi mtsha uhambelana nomsebenzi wophawu \(sgn(xy)\) owaziwa kwimathematics. Oku kuthetha ukuba abaqhubi bokuthelekisa abakhoyo banokutolika besebenzisa is syntax esitsha:

 \(\$a < \$b\) \((\$a <=> \$b) === -1\) \(\$a <= \$b\) \((\$a <=> \$b)\) !\(== 1\) \(\$a == \$b\) \((\$a <=> \$b) === 0\) \(\$a\) !\(= \$b\) \((\$a <=> \$b)\) !\(== 0\) \(\$a >= \$b\) \((\$a <=> \$b)\) !\(== -1\) \(\$a > \$b\) \((\$a <=> \$b) === 1\)

Imigaqo efanayo iyasebenza njengabaqhubi bokuthelekisa (umzekelo \([1,2,3] <=>[1,2,1]\) ilingana \(1\) ).
