       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

       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.

       -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).

       -C             Do not chdir to the script's directory (CGI only).

       -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

       -n             No php.ini file will be used

       --define foo[=bar]

       -h             This help

       -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
       -E end_code    Run PHP end_code after processing all input lines

       -s             Output HTML syntax highlighted source

       --server addr:port
       -S addr:port   Start built-in web server on the given local address and port

       -w             Output source with stripped comments and whitespace

       --zend-extension file
       -z file        Load Zend extension file

       args...        Arguments  passed  to script. Use '--' args when first argument starts with
                      '-' or script is read from stdin

       --ini          Show configuration file names

                      The configuration file for the CLI version of PHP.

                      The configuration file for the CGI version of PHP.

                      The configuration file for the version of PHP that apache2 uses.

       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.

       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:

               // your script
