因?yàn)楣揪W(wǎng)絡(luò)慢，每次想來(lái)看thinkphp5.0的手冊(cè)的時(shí)候總是要等老半天。周末在家有空就用php扒了手冊(cè)的頁(yè)面做成chm

在命令行下運(yùn)行這段代碼就會(huì)生成制作chm所需要的文件，隨便打開里面的一個(gè)html文件用瀏覽器的調(diào)試工具改改樣式保存。然后用Easy CHM

Paste_Image.png

1、點(diǎn)擊新建
2、選擇剛才下載下來(lái)的文件夾
3、自己調(diào)整一下順序
4、點(diǎn)擊編譯保存就會(huì)生存一個(gè)CHM文件

（注意代碼下載下來(lái)的可能不是很完善，如果有需要的可能自己打開html修改，或者在目錄下建立一個(gè)JS文件，代碼里有提到這個(gè)JS的路徑，用JS文件來(lái)統(tǒng)一修改代碼）
