PHP is a widely-used general-purpose scripting language that is especially suited forWeb development and can be embedded into HTML. This is the command line interfacethat enables you to do the following:You can parse and execute files by using parameter -f followed by the name of thefileto be executed.

Using parameter -r you can directly execute PHPcodesimply as you would do inside a.phpfile when using theeval()function.

It is also possible to process the standard input line by line using eitherthe parameter -R or -F. In this mode each separate input line causes thecodespecified by -R or thefilespecified by -F to be executed.You can access the input line by $argn. While processing the input lines$argicontains the number of the actual line being processed. Further morethe parameters -B and -E can be used to executecode(see -r) before andafter all input lines have been processed respectively. Notice that theinput is read fromSTDINand therefore reading fromSTDINexplicitly 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 whereaddr:portpoint 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 thedocrootpassed by the -t option.

If none of -r -f -B -R -F -E or -S is present but a single parameter is giventhen this parameter is taken as the filename to parse and execute (same aswith -f). If no parameter is present then the standard input is read andexecuted. 


-aRun PHP interactively. This lets you enter snippets of PHP code that directlyget executed. When readline support is enabled you can edit the lines and alsohave history support.
--bindpath address:port|port
-b address:port|portBind Path for external FASTCGI Server mode (CGI only).
-CDo not chdir to the script's directory (CGI only).
-qQuiet-mode. Suppress HTTP header output (CGI only).
--timing count
-T countMeasure execution time of script repeated count times (CGI only).
--php-ini path|file
-c path|fileLook forphp.inifile in the directorypathor use the specifiedfile
-nNophp.inifile will be used
--define foo[=bar]
-d foo[=bar]Define INI entryfoowith valuebar

-hThis help
-HHide script name (file) and parameters (args...) from externaltools. For example you may want to use this when a php script is started asa daemon and the command line contains sensitive data such as passwords.

The configuration file for the CLI version of PHP.
The standard configuration file will only be used whenphp-cli.inicannot be found.


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 thisto easily check which image formats you can use. If you have anydynamic modules you may want to use the same ini file that php useswhen executed from your webserver. There are more extensions whichhave 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 theresult. 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 formattedconfiguration 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 linesof 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 skipcertain input lines with your code. But note that in such cases $argi onlycounts the lines being processed by php itself. Having read this you willguess what the above program does: skipping every second input line.


You can use a shebang line to automatically invoke phpfrom scripts. Only the CLI version of PHP will ignoresuch a first line as shown below:
 // your script?>
