Can't integrate Paypal API to PHP: Fatal error: Allowed memory size of 134217728 byte -


i got error:

fatal error: allowed memory size of 134217728 bytes exhausted (tried allocate 262144 bytes) in c:\xampp\htdocs\paypaltest\vendor\paypal\rest-api-sdk-php\lib\paypal\common\paypalmodel.php on line 281

i have start.php file :

<?php  require 'vendor/autoload.php';  define('site_url', 'http://localhost:8080/paypaltest');  $paypal = new paypal\rest\apicontext(new paypal\auth\oauthtokencredential('key', 'secret')); ?>

and checkout.php file:

<?php  require 'app/start.php';  use paypal\api\payer; use paypal\api\item; use paypal\api\itemlist; use paypal\api\details; use paypal\api\amount; use paypal\api\transaction; use paypal\api\redirecturls; use paypal\api\payment;  if(isset($_post['item']) && isset($_post['price'])) {     $item = $_post['item'];     $price = $_post['price'];     $shipping_fee = 2.0;      $total = $price + $shipping_fee;      $payer = new payer();     $payer->setpaymentmethod("paypal");      $item = new item();     $item->setname($item)->setcurrency('php')->setquantity(1)->setprice($price);      $itemlist = new itemlist();     $itemlist->setitems(array($item));      $details = new details();     $details->setshipping($shipping_fee)->setsubtotal($price);      $amount = new amount();     $amount->setcurrency('php')->settotal($total)->setdetails($details);      $transaction = new transaction();     $transaction->setamount($amount)->setitemlist($itemlist)->setdescription('practice')->setinvoicenumber(uniqid());      $redirecturls = new redirecturls();     $redirecturls->setreturnurl(site_url . '/pay.php?success=true')->setcancelurl(site_url . '/pay.php?success=false');      $payment = new payment();     $payment->setintent('sale')->setpayer($payer)->setredirecturls($redirecturls)->settransactions(array($transaction));        try {         $payment->create($paypal);         echo "51";     }     catch (exception $e)     {         echo "$e";     }      $approvalurl = $payment->getapprovallink();      echo "$approvalurl"; } else {     echo "error!"; }

i have composer file used add paypal api project.

composer.json :

{     "require": {         "paypal/rest-api-sdk-php" : "1.12.0"     } }

i check paypalmodel.php , error around block of code: 

/**  * converts params array  *  * @param $param  * @return array  */ private function _converttoarray($param) {     $ret = array();     foreach ($param $k => $v) {         if ($v instanceof paypalmodel) {             $ret[$k] = $v->toarray();         } elseif (sizeof($v) <= 0 && is_array($v)) {             $ret[$k] = array();         } elseif (is_array($v)) {             $ret[$k] = $this->_converttoarray($v);         } else {             $ret[$k] = $v;         }     }     // if array empty, means empty object,     // need convert array stdclass object     // represent json string     if (sizeof($ret) <= 0) {         $ret = new paypalmodel();     }     return $ret; }

i use xampp, not use framework , testing if code work can apply website.

i change memory_limit in php.ini file higher value (512m, 1024m, 2048m etc.) , -1 still no luck.

i think problem in code causing paypalmodel.php infinite loop (my theory), cannot figure out where. new paypal having difficulties.

qa guys complained can't automate frontend testing. because our html looks same outside. lazy hack did this <template> <div :role="$options.name"> ... </div> </template> <script> export default { name: 'vmcomponentname' } </script> which takes name script , applies html. in browser get: <div role="vmcomponentname"> ... </div> line :role="$options.name" goes in every component. is there dry er solutions? please share. additional details i'll explain in details looking for. imagine have vmusercreate form creates user. test case can create user . to automatically test without role, have use following selector: .wrapper > .wrapper > .wrapper > .submit-button the test extremely brittle (will break lot). if use roles can use [role="vmusercreateform"] .submit-button selector. many folds less brittle. so basically, i'm ...
