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. SEE ALSO
