Concatenate array values on PHP-CodePudding

i have the following array:

  $datos = array(
            "TIMESTAMP" => $timestamp,
            "AMOUNT" => $amount,
            "ORDER_ID" => $Order,
            "SHA1HASH" => $firma,
            "MERCHANT_ID" => $MerchantID,
            "AUTO_SETTLE_FLAG" => '0',
            "CURRENCY" => 'EUR',
            "DCC_ENABLE" => '0',
            "HPP_VERSION" => '2',
            "HPP_CHANNEL" => 'ECOM',
            "HPP_LANG"=> $_POST['lang'],
            "HPP_CUSTOMER_EMAIL"=> $_POST['email'],
            "HPP_CUSTOMER_PHONENUMBER_MOBILE"=> $_POST['tel']
         );

I need to add to the "HPP_CUSTOMER_PHONENUMBER_MOBILE" value another value provided by POST method called 'pretel' with a "|" sign in between the pretel and the tel value, so for example if someone send trought the form pretel "34" and tel "600111222" the result would be: 34|600111222, i tryed the following code but not working:

"HPP_CUSTOMER_PHONENUMBER_MOBILE"=> $_POST['pretel']   '|'   $_POST['tel']

CodePudding user response：

In PHP concatenation is done via . operator

So do like below:

"HPP_CUSTOMER_PHONENUMBER_MOBILE"=> $_POST['pretel']."|".$_POST['tel']

Note: is used as a concatenation operator in javascript/jQuery.

In PHP is used to add numbers or combine arrays as well

operator for array in PHP?

CodePudding user response：

You can write that variable as below

"HPP_CUSTOMER_PHONENUMBER_MOBILE"=> $_POST['pretel']." | ".$_POST['tel']

You can adjust space before and after " | " as per your need.
