In JavaScript, we have Alert() and Prompt() which open up a popup box for the user.
Is there an equivalent for PHP?
$Get_['asdf']
PHP is a server side language, it can't do alert messages on the client side. But you can use javascript within the php to do the alert.
<script type="text/javascript">
window.alert("Hi There, I am the Alert Box!")
</script>
For Prompt you can do something like this -
<?php
//prompt function
function prompt($prompt_msg){
echo("<script type='text/javascript'> var answer = prompt('".$prompt_msg."'); </script>");
$answer = "<script type='text/javascript'> document.write(answer); </script>";
return($answer);
}
//program
$prompt_msg = "Please type your name.";
$name = prompt($prompt_msg);
$output_msg = "Hello there ".$name."!";
echo($output_msg);
?>
