.TH PHP 1 "2008" "The PHP Group" "Scripting Language" .SH NAME .TP 15 php \- PHP Command Line Interface 'CLI' .SH SYNOPSIS .B php [options] [ .B \-f\fP ] .IR file [[\-\-] .IR args.\|.\|. ] .LP .B php [options] .B \-r .IR code [[\-\-] .IR args.\|.\|. ] .LP .B php [options] [\-B .IR code ] .B \-R .IR code [\-E .IR code ] [[\-\-] .IR args.\|.\|. ] .LP .B php [options] [\-B .IR code ] .B \-F .IR file [\-E .IR code ] [[\-\-] .IR args.\|.\|. ] .LP .B php [options] \-\- [ .IR args.\|.\|. ] .LP \fBphp \fP[options] \fB\-a\fP .LP .SH DESCRIPTION \fBPHP\fP 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: .P You can parse and execute files by using parameter \-f followed by the name of the .IR file to be executed. .LP Using parameter \-r you can directly execute PHP .IR code simply as you would do inside a .B \.php file when using the .B eval() function. .LP 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 .IR code specified by \-R or the .IR file specified by \-F to be executed. You can access the input line by \fB$argn\fP. While processing the input lines .B $argi contains the number of the actual line being processed. Further more the paramters \-B and \-E can be used to execute .IR code (see \-r) before and after all input lines have been processed respectively. Notice that the input is read from .B STDIN and therefore reading from .B STDIN explicitly changes the next input line or skips input lines. .LP 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. .SH OPTIONS .TP 15 .PD 0 .B \-\-interactive .TP .PD 1 .B \-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. .TP .PD 0 .B \-\-php\-ini \fIpath\fP|\fIfile\fP .TP .PD 1 .B \-c \fIpath\fP|\fIfile\fP Look for .B php.ini file in the directory .IR path or use the specified .IR file .TP .PD 0 .B \-\-no\-php\-ini .TP .PD 1 .B \-n No .B php.ini file will be used .TP .PD 0 .B \-\-define \fIfoo\fP[=\fIbar\fP] .TP .PD 1 .B \-d \fIfoo\fP[=\fIbar\fP] Define INI entry .IR foo with value .IR bar .TP .B \-e Generate extended information for debugger/profiler .TP .PD 0 .B \-\-file \fIfile\fP .TP .PD 1 .B \-f \fIfile\fP Parse and execute .IR file .TP .PD 0 .B \-\-global \fIname\fP .TP .PD 1 .B \-g \fIname\fP Make variable .IR name global in script. .TP .PD 0 .B \-\-help .TP .PD 1 .B \-h This help .TP .PD 0 .B \-\-hide\-args .TP .PD 1 .B \-H Hide script name (\fIfile\fP) and parameters (\fIargs\.\.\.\fP) 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. .TP .PD 0 .B \-\-info .TP .PD 1 .B \-i PHP information and configuration .TP .PD 0 .B \-\-syntax\-check .TP .PD 1 .B \-l Syntax check only (lint) .TP .PD 0 .B \-\-modules .TP .PD 1 .B \-m Show compiled in modules .TP .PD 0 .B \-\-run \fIcode\fP .TP .PD 1 .B \-r \fIcode\fP Run PHP .IR code without using script tags .B '<?..?>' .TP .PD 0 .B \-\-process\-begin \fIcode\fP .TP .PD 1 .B \-B \fIcode\fP Run PHP .IR code before processing input lines .TP .PD 0 .B \-\-process\-code \fIcode\fP .TP .PD 1 .B \-R \fIcode\fP Run PHP .IR code for every input line .TP .PD 0 .B \-\-process\-file \fIfile\fP .TP .PD 1 .B \-F \fIfile\fP Parse and execute .IR file for every input line .TP .PD 0 .B \-\-process\-end \fIcode\fP .TP .PD 1 .B \-E \fIcode\fP Run PHP .IR code after processing all input lines .TP .PD 0 .B \-\-syntax\-highlight .TP .PD 1 .B \-s Display colour syntax highlighted source .TP .PD 0 .B \-\-version .TP .PD 1 .B \-v Version number .TP .PD 0 .B \-\-stripped .TP .PD 1 .B \-w Display source with stripped comments and whitespace .TP .PD 0 .B \-\-zend\-extension \fIfile\fP .TP .PD 1 .B \-z \fIfile\fP Load Zend extension .IR file .TP .IR args.\|.\|. Arguments passed to script. Use .B '\-\-' .IR args when first argument starts with .B '\-' or script is read from stdin .TP .PD 0 .B \-\-rfunction .IR name .TP .PD 1 .B \-\-rf .IR name Shows information about function .B name .TP .PD 0 .B \-\-rclass .IR name .TP .PD 1 .B \-\-rc .IR name Shows information about class .B name .TP .PD 0 .B \-\-rextension .IR name .TP .PD 1 .B \-\-re .IR name Shows information about extension .B name .TP .PD 0 .B \-\-rextinfo .IR name .TP .PD 1 .B \-\-ri .IR name Shows configuration for extension .B name .SH FILES .TP 15 .B php\-cli.ini The configuration file for the CLI version of PHP. .TP .B php.ini The standard configuration file will only be used when .B php\-cli.ini cannot be found. .SH EXAMPLES .TP 5 \fIphp -r 'echo "Hello World\\n";'\fP This command simply writes the text "Hello World" to standard out. .TP \fIphp \-r 'print_r(gd_info());'\fP 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: .RS \fIphp \-r 'print_r(dba_handlers(1));'\fP .RE .TP \fIphp \-R 'echo strip_tags($argn)."\\n";'\fP 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 \'\fIphp \-d html_errors=1 \-i\fP\' which uses PHP to output HTML formatted configuration information. If you then combine those two \'\fIphp \.\.\.|php \.\.\.\fP\' you'll see what happens. .TP \fIphp \-E 'echo "Lines: $argi\\n";'\fP Using this PHP command you can count the lines being input. .TP \fIphp \-R '@$l+=count(file($argn));' \-E 'echo "Lines:$l\\n";'\fP 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. .TP \fIphp \-R 'echo "$argn\\n"; fgets(STDIN);'\fP 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. .SH 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: .P .PD 0 .RS #!/bin/php .P <?php .P // your script .P ?> .RE .PD 1 .P .SH SEE ALSO For a more or less complete description of PHP look here: .PD 0 .P .B http://www.php.net/manual/ .PD 1 .P A nice introduction to PHP by Stig Bakken can be found here: .PD 0 .P .B http://www.zend.com/zend/art/intro.php .PD 1 .SH BUGS You can view the list of known bugs or report any new bug you found at: .PD 0 .P .B http://bugs.php.net .PD 1 .SH AUTHORS The PHP Group: Thies C.
