Here, we have set a function that adds "https:// to a string. Let’s say we have passed the following value −
example.com
And the output we want is with "https://" i.e. an actual link −
https://example.com
For this, you can use dot(.) notation and conditional match with preg_match().
Example
<!DOCTYPE html>
<body>
<?php
function addingTheHTTPValue($stringValue) {
if (!preg_match("~^(?:f|ht)tps?://~i", $stringValue)) {
$stringValue = "https://" . $stringValue;
}
return $stringValue;
}
echo addingTheHTTPValue("example.com");
echo "<br>";
echo addingTheHTTPValue("https://example.com");
?>
</body>
</html>Output
https://example.com https://example.com
