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 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.

       If none of -r -f -B -R -F or -E 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

       -e             Generate extended information for debugger/profiler

       --file file
       -f file        Parse and execute file

       --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.

       --info
       -i             PHP information and configuration

       --syntax-check
       -l             Syntax check only (lint)

       --modules
       -m             Show compiled in modules

       --run code
       -r code        Run PHP code without using script tags '<?..?>'

       --process-begin code
       -B code        Run PHP code before processing input lines

       --process-code code
       -R code        Run PHP code for every input line

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

       --process-end code
       -E code        Run PHP code after processing all input lines

       --syntax-highlight
       -s             Output HTML syntax highlighted source

       --version
       -v             Version number

       -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

       --rfunction    name
       --rf           name Shows information about function name

       --rclass       name
       --rc           name Shows information about class name

       --rextension   name
       --re           name Shows information about extension name

       --rextinfo     name
       --ri           name Shows configuration for extension name

       --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 exe-
            cuted 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
              ?>
