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

    Descrição

    php_sapi_name(): string|false

    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.

    Parâmetros

    Valor Retornado

    Exemplos

    Exemplo #1 php_sapi_name() 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\n";
    } else {
    echo     "You are not using CGI PHP\n";
    }
    ?>

    Notas

    Nota: An alternative approach

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

    Dica

    A potential gotcha

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