array_push と [] との比較

array_push と $array[] = $val って何が違うの

  • array_push で配列の要素足すのと、$array[] = $val で配列の要素足すのと何が違うのかわからんので調べた
  • http://pecl.php.net/package/vld を入れると処理系の OPコードを見れる

環境

[vagrant@localhost ~]$ rpm -q php
php-5.3.3-23.el6_4.x86_64

running Docker on SL6

Docket SL6 で動かすに当たっていろいろ自分で用意しないといけません

  • aufs 付きカーネル
  • iptables の addrtype
  • go
  • lxc
  • cgroup
  • docker

苦労するだけであまり価値が無い
