自动识别验证码脚本,验证码识别脚本
后端开发-php教程
经常有查下自己的车有没有违章，所以写了现在这个脚本，帮助查询自己的车是否违章。主要用到，带cookie模拟表单提交和验证码识别。具体脚本写法一起通过本文学习吧

Tesseract-OCR
验证码识别技术，Tesseract-OCR：/tesseract-ocr/tesseract
安装教学：/tesseract-ocr/tesseract
Tesseract-Ocr-For-PHP
把需要执行的命令，封装了一下
/thiagoalessio/tesseract-ocr-for-php
直接上脚本，没进行什么优化，简单了解下：
PHP

执行效果
