php html2pdf

*

网上下载了html2pdf-4.5.1.zip，

 要运行里面的实例，要先安装composer

运行html2pdf时，readme里面建议按照composer-setup.exe
安装过程中出现openssl的问题，在php.ini中开启相应extension即可，
路径写绝对路径，否则按默认路径找不到

在html2pdf的文件路径下，cmd运行composer install

安装dependencies

D:softwareWebServerapacheApache24htdocshtml2pdf>composer install
Loading composer repositories with package information
Updating dependencies (including require-dev)
  - Installing tecnickcom/tcpdf (6.2.12)

运行时出现的问题

修改以上gd extension问题，修改php.ini

extension=D:softwarePhpWinphp56extphp_gd2.dll
;extension=php_gettext.dll
;extension=php_gmp.dll
;extension=php_intl.dll
;extension=php_imap.dll
;extension=php_interbase.dll
;extension=php_ldap.dll
;extension=php_mbstring.dll
;extension=php_exif.dll      ; Must be after mbstring as it depends on it
;extension=php_mysql.dll
;extension=php_mysqli.dll
;extension=php_oci8_12c.dll  ; Use with Oracle Database 12c Instant Client
extension=D:softwarePhpWinphp56extphp_openssl.dll //这是安装composer时出现错误要改的

 *

至此，运行成功
