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
Tag | Description |
--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 scripts 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.
|
--help
-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

code without using script tags
<?..?> |
--process-begin code
-B code | |

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

|
--version
-v |
Version number
|
--stripped
-w |
Output source with stripped comments and whitespace
|

--rextension |
name |
--re |
name Shows information about extension
name |
--rextinfo |
name |
--ri |
name Shows configuration for extension
name |
--ini |
Show configuration file names
|
FILES
Tag | Description |
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
Tag | Description |
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 ...' youll 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
?>
