I'm new learning php, but i'm stuck in the very beginning . Whatever method I try in PHP but I could not display variable data in output.. below is code which is copy pasted from internet, even in that I cannot see output of $username...pls help me!
<html>
<body>
<h1>Hi Jacob</h1>
<h3>Demonstrates using a variable</h3>
<?php
$userName = "Jacob";
print Hi, $userName;
?>
</body>
</html>
In output it " Hi, $username " is getting displayed. not the data of variable
You have print Hi, $userName;
which should be
print "Hi, $userName";
you need to wrap that line in quotes.
or concatenate (along with quotes)
print "Hi, " .$userName;
had you left out the Hi, and had done
print $userName;
would have printed Jacob so that's also acceptable.
any text needs to be wrapped in quotes.
This is also acceptable:
print 'Hi, ' .$userName;
but this
print 'Hi, $userName';
would print out Hi, $userName instead of the intended name assigned from the variable, so it's best to use double quotes when wrapping text and variables inside the same quotes.
there are lots of way to print in php
print "Hi". $username;
print "Hi $username";
print "HI {$username}";
you can you anyone. you can also use echo to print you variable.
if you want to print array then you can use
print_r($user);
try this one, Php Concatenation possible only with dot(.). Also add the quotes around the string like "Hi"
print "Hi " . $userName;
instead of
print Hi, $userName;
Very simple, Replace your PHP code with below...
<?php
$userName = "Jacob";
//print Hi, $userName;
print "Hi, ".$userName;
?>
Note: For print any static content(string) you must use single or double "Quotation Marks". You can use print or echo keyword for displaying your code in PHP file.
.phpextension? Are you running this from WWW or local computer? Is PHP installed, the list goes on...print 'Hi ' . $userName;
