Implementation of the method of detecting orc in PHP ID card

This article mainly introduces the PHP identity card recognition Orc method implementation, has a certain reference value, now share to everyone, the need for friends can refer to

First create an HTML and transfer it to a PHP file in JSON format

<! DOCTYPE HTML PUBLIC "-//W3C//DTD XHTML 1.0 transitional//en" "Http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd "> 
 Create another upload.php 
 

<?phpheader ("content-type:text/html; Charset=utf-8 ")/** * Base64 image upload * @param $base 64_img * @return Array */$base 64_img = Trim ($_post[' img '); $up _dir = ' Uploa D/';//stored in the current directory under the upload folder $fi_dir = ' ok_upload/';//stored in the current directory under the Upload folder if (!file_exists ($up _dir)) {mkdir ($up _dir,0777) ;}    if (Preg_match ('/^ (data:\s*image\/(\w+); base64,)/', $base 64_img, $result)) {$type = $result [2]; if (In_array ($type, Array (' pjpeg ', ' jpeg ', ' jpg ', ' gif ', ' BMP ', ' png '))) {$new _file = $up _dir.date (' Ymdhis_ ').        $type; if (file_put_contents ($new _file, Base64_decode (Str_replace ($result [1], ", $base 64_img)))) {$img _path = Str_replace (' .. /.. /: ', ', $new _file); $path = ' upload/'; $data = file_get_contents ($img _path); $base = Base64_encode ($data); $appkey = '                Lzju1grfwh6uadx2 '; $params = Array (' app_id ' = ' 1106920947 ', ' image ' = + $base 64, ' Card_type ' = ' 0 ', ' time_stamp ' + strval (Time ()), ' nonce_str ' = Strval ( RanD ()), ' sign ' + ', ', ' $params [' sign '] = Getreqsign ($params, $appkey);//execute API call to ' HTTPS://API '.

So we can identify the information on the ID card.
