PHP脚本自动识别验证码查询汽车违章

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。

Tesseract-OCR

验证码识别技术，Tesseract-OCR：https://github.com/tesseract-ocr/tesseract

安装教程：https://github.com/tesseract-ocr/tesseract

Tesseract-Ocr-For-PHP

把需要执行的命令，封装了一下

直接上脚本，没进行什么优化，简单了解下：

PHP

    <?php
    require 'TesseractOCR.php';
    function weizhang($car_code, $fdjh)
    {
      $shanghui = mb_substr($car_code, 0, 1, 'utf-8');
      $pre = array(
        '冀' => 'he',
        '云' => 'yn'
      );
      $url_pre = $pre[$shanghui];
      $headers = array(
        'Host: '.$url_pre.'.122.gov.cn',
        'Origin: http://'.$url_pre.'.122.gov.cn',
        'Referer: http://'.$url_pre.'.122.gov.cn/views/inquiry.html?q=j',

      if (strlen($code) != 4) {

      }
      $data = array(

    }
    $count = 0;
