Question

guys im looking for a comprehensive code to check if a visitor is in index.php then showing some lines to him

i mean i want to consider every possibility for this code

function curPageURL() {
 $pageURL = 'http';
 if ($_SERVER["HTTPS"] == "on") {$pageURL .= "s";}
 $pageURL .= "://";
 if ($_SERVER["SERVER_PORT"] != "80") {
  $pageURL .= $_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"];
 } else {
  $pageURL .= $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"];
 }
 return $pageURL;
}

$curentUrl = curPageURL();


if (preg_match("/index.php/",$curentUrl) || preg_match("/index.html/",$curentUrl)) {

}

but im looking for a more complete code to see if user is in index page of my website

Answer 1

Actually this curPageURL() function has nothing to do here

 if ($_SERVER['PHP_SELF'] == "/index.php")

is enough.
But on most PHP sites index.php doesn’t mean only index page. but it can be whole site too.
Without complete circumstances this question is too broad to answer.
