PHP整合PayPal支付,php整合paypal


簡單整理一下PHP項目整合PayPal支付功能。

一、表單的構建:


二、IPN驗證部分

<?phpclass paypal {  var $ipn_data = array();     // array contains the POST values for IPN  var $fields = array();      // 提交給Paypal的表單參數,例:item_name=iPhone 6,quantity=1,amount=499,currency_code=USD等所有表單資訊,                     // 在調用驗證IPN之前事先需要初始化好  var $paypal_url = 'https://www.paypal.com/cgi-bin/webscr';//sandbox:https://www.sandbox.paypal.com/cgi-bin/webscr    function validate_ipn() {//驗證IPN      // parse the paypal URL      $url_par=parse_url($this->paypal_url);      // generate the post string from the _POST vars aswell as load the      // _POST vars into an arry so we can play with them from the calling      // script.      $post_str = '';      foreach ($_POST as $field=>$value) {        $this->ipn_data["$field"] = $value;        $post_str .= $field.'='.urlencode(stripslashes($value)).'&';      }      $post_str.="cmd=_notify-validate"; // append ipn command      // open the connection to paypal      $fp = fsockopen($url_par[host],"80",$errnum,$errstr,30);      if(!$fp) {        // could not open the connection.        return false;      } else {        // Post the data back to paypal        fputs($fp, "POST ".$url_par[path]." HTTP/1.1\r\n");        fputs($fp, "Host: ".$url_par[host]."\r\n");        fputs($fp, "Content-type: application/x-www-form-urlencoded\r\n");        fputs($fp, "Content-length: ".strlen($post_str)."\r\n");        fputs($fp, "Connection: close\r\n\r\n");        fputs($fp, $post_str . "\r\n\r\n");        // loop through the response from the server and append to variable        while(!feof($fp)) {          $this->validate_ipn_response .= fgets($fp, 1024);        }        fclose($fp); // close connection     }    if (eregi("VERIFIED",$this->validate_ipn_response)) {      return true;    } else {      return false;    }  }}?>
