DESCRIPTION
       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 pro-
       cessing the input lines $argi contains the number of the actual line being processed. Fur-
       ther  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 embedded 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 support 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

       --global name
       -g name	      Make variable name global in script.

       -h	      This help

       --hide-args
       -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.

       --process-file file
       -F file	      Parse and execute file for every input line

       --process-end code

       --ini	      Show configuration file names

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 following 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:
	    skipping 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
	      ?>
