PHP图片识别

1. PHP与图片识别

2. PHP图片识别接口

<?php
class Sample
{
    public function run()
    {
        $curl = curl_init();
        curl_setopt_array($curl, array(
            CURLOPT_URL => "https://netocr.com/api/recoglenliu.do",
            CURLOPT_RETURNTRANSFER => true,
            CURLOPT_ENCODING => '',
            CURLOPT_MAXREDIRS => 10,
            CURLOPT_TIMEOUT => 0,
            CURLOPT_FOLLOWLOCATION => true,
            CURLOPT_HTTPVERSION => CURL_HTTP_VERSION_1_1,
            CURLOPT_CUSTOMREQUEST => 'POST',
            CURLOPT_POSTFIELDS => array(
                'img' => '/9j',
                'key' => 'Mg',
                'secret' => '36',
                'typeId' => '2008',
                'outvalue' => ''
            ),
        ));
        $response = curl_exec($curl);
        curl_close($curl);
        return $response;
    }
}

PHP正则提取

1. PHP正则表达式

PHP内置了正则表达式支持，可以用于字符串匹配、替换、分割等操作。以下是一些常用的PHP正则表达式：

  • '/\d/'：匹配数字
  • '/\w/'：匹配字母、数字和下划线
  • '/\s/'：匹配空白字符

2. PHP正则提取图片src

<?php
header("Content-type:text/html;charset=utf-8");
$str = '<li><a href"https://www.mzitu.com/169017" target"blank"><img src"https://i.meizitu.net/thumbs/2019/02/16901710d01236.jpg" alt"肉感美女刘钰儿性感图片，丰满成熟女人味十足" width"236" height"354" /></a><span><a href"https://www.mzitu.com/169017" target"blank">肉感美女刘钰儿性感图片，丰满成熟女人味十足</a></span><span class"time">2019-02-14</span></li>';

preg_match_all('/<img\s+src="([^"]+)"\s*/', $str, $matches);
foreach ($matches[1] as $match) {
    echo $match . "<br>";
}
?>
