Top Forums Web Development Php script prints values but not seen in browser Post 302965000 by Akshay Hegde on Friday 22nd of January 2016 12:51:19 AM

In short, if you run php script on command line, you will get something like this
Code:
[akshay@localhost tmp]$ php -r 'echo `whoami`;'
akshay

At the same time, If you're trying to trigger it from a web interface, you will receive output as
Code:
apache

You need to check following
  1. The user running the code (you vs apache)
  2. SELinux (disable SELinux)
  3. PATH
  4. If you are running some time consuming big programs, then max_execution_time or memory_limit in php.ini
    program executed by browser (with apache) and for cli (terminal - without apache) may have different values for max_execution_time or memory_limit - usual php.ini for cli has more memory and it could run for longer period of time
  5. Whether user apache has enough permission to read, write and execute programs/files

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
