PHP is a widely-used general-purpose scripting language that is especially suited for Web development and
       can be embedded into HTML. This is the command line interface that enables you to do the following:

       You can parse and execute files by using parameter -f followed by the name of the file to be executed.

       Using parameter -r you can directly execute PHP code simply as you would do inside a .php file when using
       the eval() function.

       It  is  also  possible to process the standard input line by line using either the parameter -R or -F. In
       this mode each separate input line causes the code specified by -R or the file  specified  by  -F  to  be
       executed.   You  can  access the input line by $argn. While processing the input lines $argi contains the
       number of the actual line being processed. Further more the parameters -B and -E can be used  to  execute
       code (see -r) before and after all input lines have been processed respectively. Notice that the input is
       read  from  STDIN  and therefore reading from STDIN explicitly changes the next input line or skips input
       lines.

       PHP also contains an built-in web server for application development purpose.  By  using  the  -S  option
       where  addr:port  point  to a local address and port PHP will listen to HTTP requests on that address and
       port and serve files from the current working directory or the docroot passed by the -t option.

       If none of -r -f -B -R -F -E or -S is present but a single parameter is  given  then  this  parameter  is
       taken  as  the  filename  to  parse  and  execute  (same as with -f). If no parameter is present then the
       standard input is read and executed.

php-r'echo"HelloWorld\n";'
            This command simply writes the text "Hello World" to standard out.

       php-r'print_r(gd_info());'
            This shows the configuration of your gd extension. You can use this  to  easily  check  which  image
            formats  you can use. If you have any dynamic modules you may want to use the same ini file that php
            uses when executed from your webserver. There are more extensions which have such  a  function.  For
            dba use:
            php-r'print_r(dba_handlers(1));'php-R'echostrip_tags($argn)."\n";'
            This  PHP  command strips off the HTML tags line by line and outputs the result. To see how it works
            you can first look at the following PHP command ´php-dhtml_errors=1-i´ which uses PHP  to  output
            HTML formatted configuration information. If you then combine those two ´php...|php...´ you'll see
            what happens.

       php-E'echo"Lines:$argi\n";'
            Using this PHP command you can count the lines being input.

       php-R'@$l+=count(file($argn));'-E'echo"Lines:$l\n";'
            In this example PHP expects each input line being a file. It counts all lines of the files specified
            by  each  input line and shows the summarized result.  You may combine this with tools like find and
            change the php scriptlet.

       php-R'echo"$argn\n";fgets(STDIN);'
            Since you have access to STDIN from within -B -R -F and -E you can skip  certain  input  lines  with
            your  code.  But  note that in such cases $argi only counts the lines being processed by php itself.
            Having read this you will guess what the above program does: skipping every second input line.

       php-cgi - PHP Common Gateway Interface 'CGI' command

--interactive-a             Run PHP interactively. This lets  you  enter  snippets  of  PHP  code  that  directly  get
                      executed.  When  readline  support is enabled you can edit the lines and also have history
                      support.

       --bindpathaddress:port|port-baddress:port|port
                      Bind Path for external FASTCGI Server mode (CGI only).

       --no-header-q             Quiet-mode. Suppress HTTP header output (CGI only).

       --timingcount-Tcount       Measure execution time of script repeated count times (CGI only).

                      want  to  use  this when a php script is started as a daemon and the command line contains
                      sensitive data such as passwords.

       You can use a shebang line to automatically invoke php from scripts. Only the CLI  version  of  PHP  will
       ignore such a first line as shown below:

              #!/bin/php
              <?php
               // your script
              ?>
