PHP實(shí)現(xiàn)的掃瞄器檢查類(lèi)_

1、PHP實(shí)現(xiàn)的掃瞄器檢查類(lèi)_ 這篇文章主要介紹了PHP實(shí)現(xiàn)的掃瞄器檢查類(lèi),結(jié)合實(shí)例形式具體分析了PHP掃瞄器操作的相關(guān)技巧,特別簡(jiǎn)潔有用,需要的伴侶可以參考下 ?php /原：epsilon7 /SonyMusic(emailsonymusic/email) class BrowserDetector var $UA = ; /$HTTP_USER_AGENT的內(nèi)容 var $BROWSER= Unknown; /掃瞄器類(lèi)型 var $PLATFORM = Unknown; /操作系統(tǒng) var $VERSION= ; /掃瞄器版本號(hào) var $MAJORVER = ; /掃瞄器主版本號(hào) var
