To check whether a string has no whitespace, use the preg_match() in PHP.
The syntax is as follows
preg_match('/\s/',$yourVariableName);Example
The PHP code is as follows
<!DOCTYPE html>
<html>
<body>
<?php
$name="John Smith";
if ( preg_match('/\s/',$name) ){
echo "The name (",$name,") has the space";
} else {
echo "The Name (",$name,") has not the space";
}
?>
</body>
</html>Output
This will produce the following output
The name (John Smith) has the space
