PHP Variable from echo variable of sql table

Question

I've got a PHP files where inside i've got this line:

source: "<?php echo $this->row->cdkey;?>"

that returns a number like 124982149

I need to pass this into a php variable

But if i try:

$variable = '<?php echo $this->row->cdkey;?>';

it doesn't retun anything.

How can i solve this without connecting to mysql?

Answer 1

if you can change code in php file like below

return $this->row->cdkey;

Call it where you want

$fileContent = file_get_contents($filePath);
$variable =  eval($fileContent);

if you can not change code in php file than you just use CURL link

Answer 2

You are using php to save this to a variable, like this.

$variable = $this->row->cdkey;

There is no need to open and close php tag inside another php tag, Then simply echo or print $variable anywhere to get $this->row->cdkey .
