PHP CURL Open Ai Remove The Quotes From Post Data

Question

Below is my PHP Curl script that works to post to Open AI, this is all working as it should.

I want to be able to set the values from posted data like this.

 $getOpenAITemperature = $_POST[OpenAITemperature]; 
 $getmaxtokens = $_POST[OpenAIMaximumLength]; 
 $getTopp = $_POST[OpenAITopP];`

But when I do it added quotes to the posted values and it stops working.

Like this.

 $postData = [
  'model' => $getOpenAIModel,
  'prompt' => $getRequest,
  'temperature' => "0.24",
  'max_tokens => "250",
  'top_p' => "1",

But it needs to look like this to work.

 $postData = [
   'model' => $getOpenAIModel,
   'prompt' => $getRequest,
   'temperature' => 0.24,
   'max_tokens => 250,
   'top_p' => 1,

How can I remove the quotes around the numbers ? The quotes around the model and prompt are fine its just the numbers.

*** The script below here works fine ***

  $getOpenAITemperature = 0.5;
  $getmax_tokens = 250;
  $gettop_p = 1;


  $OPENAI_API_KEY = "sk-123";
  $getOpenAIModel = "text-davinci-003";
  $getRequest "My Question";
  $ch = curl_init();
  $headers  = [
        'Accept: application/json',
        'Content-Type: application/json',
        'Authorization: Bearer '.$OPENAI_API_KEY.''
    ];
 $postData = [
   'model' => $getOpenAIModel,
   'prompt' => $getRequest,
   'temperature' => $getOpenAITemperature,
   'max_tokens' => $getTopp,
   'top_p' => $getmaxtokens,
   'best_of' => 2,
   'frequency_penalty' => 0.0,
   'presence_penalty' => 0.0,
    'stop' => '["\n"]',
  ];

  curl_setopt($ch, CURLOPT_URL, 'https://api.openai.com/v1/completions');
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
  curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
  curl_setopt($ch, CURLOPT_POST, 1);
  curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($postData)); 

  $result = curl_exec($ch);`

I have tried a number of things like php trim() and str_replace but nothing worked.

You can cast the strings to an int or a float like so:

$postData['temperature'] = (float) $postData['temperature'];
$postData['max_tokens'] = (int) $postData['max_tokens'];

Check the PHP docs for type casting https://www.php.net/manual/en/language.types.type-juggling.php#language.types.typecasting
