准备工作
1、百度智能云申请接口（每天500次免费）
2、创建应用
3、下载SDK包
上代码
<?php
require_once 'baiduocr/AipOcr.php';
const APP_ID = '23254777';
const API_KEY = 'xakRI2tKffO7Qfp6vyvO5slR';
const SECRET_KEY = 'QhmGnOmgVEgRdKrHmUxgFtwBGufntRGg';
$client = new AipOcr(APP_ID, API_KEY, SECRET_KEY);
echo '<img src="./img/00000031.jpg" />';
$image = file_get_contents('./img/00000031.jpg');
$options = array();
$options["language_type"] = "CHN_ENG";
$options["detect_direction"] = "true";
// $options["detect_language"] = "true";
// $options["probability"] = "true";
// 带参数调用通用文字识别, 图片参数为本地图片
$rs = $client->basicGeneral($image, $options);
// 本次图片文本从右往前读，需要改变顺序
$data = array_reverse($rs['words_result']);
foreach ($data as $k => $v) {
if(is_array($v) && !empty($v)){
foreach ($v as $key => $value) {
echo "<pre>";
echo $value;
}
}
