Sometimes, when I run some PHP script, I need to know if it is running on the command line or not, because if it is running on the command line, I can perform a different action.
Is there any way to detect if the script is running on the command line or if it is running on a server?
Use the function php_sapi_name() , if the return is "cli" , is running on the line command.
The PHP documentation says:
string php_sapi_name(void)Returns a lowercase string that describes the type of interface between the web server and PHP (Server API, SAPI). In CGI PHP, this string is "cgi", in mod_php for Apache, this string is "apache" and so on.
Example:
if (php_sapi_name() == "cli") {
// Executando na linha de comando
} else {
// Executando no servidor
}
You can do this by checking the value of PHP_SAPI .
If it is "cli" , it is running on the command line.
Example:
if (PHP_SAPI === 'cli') {
// Está na linha de comando
} else {
// Está rodando no via servidor
}
Note : When the script is running on a server, the values returned by the constant PHP_SAPI or the php_sapi_name function may vary depending on the server. For example, when running on Apache2, the returned value will be "apache2handler" , if you use PHP's built-in server , the returned value is "cli-server" . But the value returned when using the command line is always "cli" .
