How to check if a php script is running using shell command line or command line?

Answer 1

Use the php_sapi_name function:

 if(php_sapi_name() == 'cli') { // running from CLI } 

From Manual :

Returns a string string describing the type of interface (server API, SAPI) that PHP uses. For example, in the CLI PHP this line will be "cli", whereas with Apache it can have several different values ​​depending on the exact SAPI used. Possible values ​​are listed below.

Answer 2

Here is a shell solution if you are really interested in this:

 ps -ef | grep $scriptname | grep -v grep; if [[ $? -eq 0 ]]; then echo "PROCESS IS RUNNING"; fi 

Explanation:

 ps -ef ## lists all running processes grep $scriptname ## keep only the process with the name we suppply grep -v grep ## the previous grep will show up in the ps -ef so this prevents false positives. if [[ $? -eq 0 ]]; then echo "PROCESS IS RUNNING"; fi ## if the last line returns something then process is running.

You can check them out:

 if(isset($_SERVER['HTTP_USER_AGENT']) && strpos($_SERVER['HTTP_USER_AGENT'],"CLI") !== FALSE) { /// }
