如何向变量添加输入？

Question

I have this form

<form action="process.php" method="post"> 
Team Name: <input type="text" name="teamname" /> 
<input type="submit" />
</form>

and this is my php code

$teamname = $_POST['teamname'];

$namelist = "Lakers";

so let's say two people have submitted their team names as Spurs and Rangers

so how do I make the namelist like this and grow as more people submit their team names..

$namelist = "Lakers, Spurs, Rangers";

I have done it in array_push with arrays, but technically i can't call them.

Answer 1

you need to save the names to file/database. variable save in the memory of the machine and deleted after the scripts done.

$names = array(); // empty array

$names[] = $_POST['teamname']; // add the $_POST['teamname'] to the array

var_dump($names); // prints the names array.

// now the script done, and all the data in the variables will flush from the memory.
