回複討論(解決方案)
更新的也太快了點吧
不是吧！前幾天剛把php5.5.6安裝上去...看來這次漏洞還不小，緊急發布
愁苦,那?多服?器咋更新啊....
聖誕節前最後一版。
生產環境還是5.2.17 不準備升級 穩定才是王道
緊急更新。。。
5.3比5.2快10倍
5.4比5.3快10倍
生產環境還是5.2.17 不準備升級 穩定才是王道
5.3比5.2快10倍
5.4比5.3快10倍
生產環境還是5.2.17 不準備升級 穩定才是王道
對於一般網站來說，這10倍基本上是感覺不出來的，並且還要承擔不穩定的風險，還不如最佳化一下緩衝收益高。
Fixed whitespace part of #64874 ("json_decode handles whitespace and case-sensitivity incorrectly").
