DESCRIPTION
       PHP  is  a widely-used general-purpose scripting language that is espe-
       cially 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 exe-
       cuted.  You can access the input line by $argn.  While  processing  the
       input  lines  $argi  contains  the number of the actual line being pro-
       cessed. 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.
OPTIONS
       --interactive
       -a             Run  PHP  interactively. This lets you enter snippets of
                      PHP code that directly get executed. When readline  sup-
                      port  is  enabled  you  can edit the lines and also have
                      history support.
       --bindpath address:port|port
       -b address:port|port
                      Bind Path for external FASTCGI Server mode (CGI only).
       --no-chdir
       -C             Do not chdir to the script's directory (CGI only).
       --no-header
       -q             Quiet-mode. Suppress HTTP header output (CGI only).
       --timing count
       -T count       Measure execution time of script  repeated  count  times
                      (CGI only).
       --php-ini path|file
       -c path|file   Look  for  php.ini file in the directory path or use the
                      specified file
       --no-php-ini
       -n             No php.ini file will be used
       --define foo[=bar]
       -d foo[=bar]   Define INI entry foo with value bar
       -e             Generate extended information for debugger/profiler
       --file file
       -f file        Parse and execute file

       -H             Hide script name (file) and  parameters  (args...)  from
                      external  tools.  For  example  you may want to use this
                      when a php script is started as a daemon and the command
                      line contains sensitive data such as passwords.

FILES
       php-cli.ini    The configuration file for the CLI version of PHP.
       php.ini        The standard configuration file will only be  used  when
                      php-cli.ini cannot be found.
EXAMPLES
       php -r 'echo "Hello World\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 'echo strip_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  follow-
            ing PHP command 'php -d html_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: skip-
            ping every second input line.
TIPS
       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
              ?>
