php_sapi_name - Returns the type of interface between web server and PHP

SYNOPSIS

       string php_sapi_name (void  )

DESCRIPTION

	Returns  a  lowercase  string  that describes the type of interface (the Server API, SAPI) that PHP is using. For example, in CLI PHP this
       string will be "cli" whereas with Apache it may have several different values depending on the exact SAPI used. Possible values are  listed
       below.

RETURN VALUES

	Returns the interface type, as a lowercase string.

	Although  not  exhaustive,  the  possible  return values include aolserver, apache, apache2filter, apache2handler, caudium, cgi (until PHP
       5.3), cgi-fcgi, cli, cli-server, continuity, embed, fpm-fcgi, isapi, litespeed, milter, nsapi, phttpd, pi3web, roxen, thttpd, tux, and web-
       james.

EXAMPLES

       Example #1

	      php_sapi_name(3) example

	       This example checks for the substring cgi because it may also be cgi-fcgi.

	      <?php
	      $sapi_type = php_sapi_name();
	      if (substr($sapi_type, 0, 3) == 'cgi') {
		  echo "You are using CGI PHP
";
	      } else {
		  echo "You are not using CGI PHP
";
	      }
	      ?>

NOTES

       Note

	      An alternative approach

	       The PHP constant PHP_SAPI has the same value as php_sapi_name(3).

       Tip

	      A potential gotcha

	       The defined SAPI may not be obvious, because for example instead of apache it may be defined as apache2handler or apache2filter.
