I am have troubles trying to print out < > symbols in HTML using PHP.
I am appending a string "<machine>" to a variable.
Example:
$output .= " <machine> ";
echo $output;
I tried using escapes, but that didn't help. Any advice?

htmlspecialchars() Function: The htmlspecialchars() function is an inbuilt function in PHP which is used to convert all predefined characters to HTML entities. Syntax: string htmlspecialchars( $string, $flags, $encoding, $double_encode )
The Scope Resolution Operator (also called Paamayim Nekudotayim) or in simpler terms, the double colon, is a token that allows access to static, constant, and overridden properties or methods of a class.
php function check_string($my_string){ $regex = preg_match('[@_! #$%^&*()<>?/|}{~:]', $my_string); if($regex) print("String has been accepted"); else print("String has not been accepted"); } $my_string = 'This_is_$_sample!
> = >< = <
Or you can use htmlspecialchars.
$output .= htmlspecialchars(" <machine> ");
If you are outputting HTML, you cannot just use < and > : you must use the corresponding HTML entities : < and >
If you have a string in PHP and want to automatically replace those characters by the corresponding HTML entities, you'll be interested by the htmlspecialchars() function (quoting) :
The translations performed are:
'&'(ampersand) becomes'&''"'(double quote) becomes'"'whenENT_NOQUOTESis not set."'"(single quote) becomes'''only whenENT_QUOTESis set.'<'(less than) becomes'<''>'(greater than) becomes'>'
In your case, a portion of code like this one :
$output = " ";
echo htmlspecialchars($output, ENT_COMPAT, 'UTF-8');
Would get you the following HTML code as output :
<machine>
And, just in case, if you want to encode more characters, you should take a look at the htmlentities() function.
