NAME

       php            PHP Command Line Interface ’CLI’


SYNOPSIS

       php [options] [ -f ] file [[--] args...]

       php [options] -r code [[--] args...]

       php [options] [-B code] -R code [-E code] [[--] args...]

       php [options] [-B code] -F file [-E code] [[--] args...]

       php [options] -- [ args...]



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 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 paramters -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 interactively

       --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

                      when a php script is started as a daemon and the command

       -l             Syntax check only (lint)

       --modules
       -m             Show compiled in modules

       --run code
       -r code        Run PHP code without using script tags β€β€™<?..?>β€β€™

       --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             Display colour syntax highlighted source

       --version
       -v             Version number

       --stripped
       -w             Display source with stripped comments and whitespace

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

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


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 Β΄php -d html_errors=1 -iΒ΄ which uses PHP  to
            output  HTML formatted configuration information. If you then com-
            bine those two Β΄php ...|php ...Β΄ 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  beeing  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
              ?>
