在数组中分配PHP变量

Question

I'm working on integrating external code. Following is the code:

if(count($_POST))
pay_page(array('key'=>'gtKFFx','txnid'=>'shanil','amount'=>'100');

There are static values. I want to assign php variables to this array:

if(count($_POST))
pay_page(array('key'=>'gtKFFx','txnid'=><?php echo $b; ?>,'amount'=>'10');

How do I achieve that? Can somebody help?

Answer 1

if(count($_POST))
    pay_page(array('key'=>'gtKFFx','txnid'=> $b,'amount'=>'10'));

This should work.

Answer 2

Just write there $b , no <?php etc. You are in PHP script, so there is no reason why to begin PHP script again.

if(count($_POST))
    pay_page(array('key' => 'gtKFFx', 'txnid' => $b, 'amount' => 10));

Note:
- There was missing bracket at the end of the script
- amount is number, so it should be written without quotes.

Answer 3

If you are in out of php script ie your code is correct.

Now you are in php script only. so echo is not required.

so just use like below code:

if(count($_POST))
    pay_page(array('key' => 'gtKFFx', 'txnid' => $b, 'amount' => 10));

I think this is useful.
