-a |
--interactive |
Run PHP interactively. For more information, see the Interactive shell
section.
|
-b |
--bindpath |
Bind Path for external FASTCGI Server mode (CGI
only).
|
-C |
--no-chdir |
Do not chdir to the script's directory (CGI only).
|
-q |
--no-header |
Quiet-mode. Suppress HTTP header output
(CGI only).
|
-T |
--timing |
Measure execution time of script repeated count
times (CGI only).
|
-c |
--php-ini |
Specifies either a directory in which to look for
php.ini, or a custom INI file
(which does not need to be named php.ini), e.g.:
If this option is not specified, php.ini is searched for in the
default locations.
|
-n |
--no-php-ini |
Ignore php.ini completely.
|
-d |
--define |
Set a custom value for any of the configuration
directives allowed in php.ini. The syntax is:
-d configuration_directive[=value]
Example #1 Example of using -d to set an INI setting
# Omitting the value part will set the given configuration directive to "1"
$ php -d max_execution_time
-r '$foo = ini_get("max_execution_time"); var_dump($foo);'
string(1) "1"
# Passing an empty value part will set the configuration directive to ""
php -d max_execution_time=
-r '$foo = ini_get("max_execution_time"); var_dump($foo);'
string(0) ""
# The configuration directive will be set to anything passed after the '=' character
$ php -d max_execution_time=20
-r '$foo = ini_get("max_execution_time"); var_dump($foo);'
string(2) "20"
$ php
-d max_execution_time=doesntmakesense
-r '$foo = ini_get("max_execution_time"); var_dump($foo);'
string(15) "doesntmakesense"
|
-e |
--profile-info |
Activate the extended information mode, to be used by a
debugger/profiler.
|
-f |
--file |
Parse and execute the specified file. The
-f is optional and may be omitted - providing just
the filename to execute is sufficient.
|
-h and -? |
--help and --usage |
Output a list of
command line options with one line descriptions of what they do.
|
-i |
--info |
Calls phpinfo(), and prints out the results.
If PHP is not working correctly, it is advisable to use the command
php -i and see whether any error
messages are printed out before or in place of the information tables.
Beware that when using the CGI mode the output is in
HTML and therefore very large.
|
-l |
--syntax-check |
Syntax check but do not execute the given PHP code.
The input from standard input will be processed if no filenames are specified,
otherwise each filename will be checked.
On success, the text
No syntax errors detected in <filename> is
written to standard output.
On failure, the text Errors parsing <filename>
is written to standard output in addition to the internal parser error.
If any failures are found in the specified files (or standard input),
the shell return code is set to -1 , otherwise the
shell return code is set to 0 .
This option won't find fatal errors (like undefined functions) that
require executing the code.
Note:
Prior to PHP 8.3.0, it was only possible to specify one filename to
be checked.
Note:
This option does not work together with the -r
option.
|
-m |
--modules |
Example #2 Printing built in (and loaded) PHP and Zend modules
$ php -m
[PHP Modules]
xml
tokenizer
standard
session
posix
pcre
overload
mysql
mbstring
ctype
[Zend Modules]
|
-r |
--run |
Allows execution of PHP included directly on the command line.
The PHP start and end tags (<?php and
?> ) are not
needed and will cause a parse error if present.
Note:
Care must be taken when using this form of PHP not
to collide with command line variable substitution done by the
shell.
Example #3 Getting a syntax error when using double quotes
$ php -r "$foo = get_defined_constants();"
PHP Parse error: syntax error, unexpected '=' in Command line code on line 1
Parse error: syntax error, unexpected '=' in Command line code on line 1
The problem here is that sh/bash performs variable substitution
even when using double quotes " . Since the
variable $foo is unlikely to be defined, it
expands to nothing which results in the code passed to
PHP for execution actually reading:
The correct way would be to use single quotes ' .
Variables in single-quoted strings are not expanded
by sh/bash.
Example #4 Using single quotes to prevent the shell's variable
substitution
$ php -r '$foo = get_defined_constants(); var_dump($foo);'
array(370) {
["E_ERROR"]=>
int(1)
["E_WARNING"]=>
int(2)
["E_PARSE"]=>
int(4)
["E_NOTICE"]=>
int(8)
["E_CORE_ERROR"]=>
[...]
If using a shell other than sh/bash, further issues might be
experienced - if appropriate, a bug report should be opened at
» https://github.com/php/php-src/issues.
It is still easy to run into trouble when trying to use variables
(shell or PHP) in command-line code, or using backslashes for
escaping, so take great care when doing so. You have been warned!
Note:
-r is available in the CLI SAPI, but not in the
CGI SAPI.
Note:
This option is only intended for very basic code, so some
configuration directives (such as auto_prepend_file and auto_append_file) are ignored
in this mode.
|
-B |
--process-begin |
PHP code to execute before processing stdin.
|
-R |
--process-code |
PHP code to execute for every input line.
There are two special variables available in this mode:
$argn and $argi.
$argn will contain the line PHP is processing at
that moment, while $argi will contain the line
number.
|
-F |
--process-file |
PHP file to execute for every input line.
|
-E |
--process-end |
PHP code to execute after processing the input.
Example #5 Using the -B, -R and
-E options to count the number of lines of a
project.
$ find my_proj | php -B '$l=0;' -R '$l += count(@file($argn));' -E 'echo "Total Lines: $l\n";'
Total Lines: 37328
|
-S |
--server |
Starts built-in web
server.
|
-t |
--docroot |
Specifies document root for built-in web server.
|
-s |
--syntax-highlight and --syntax-highlighting |
Display colour syntax highlighted source.
This option uses the internal mechanism to parse the file and writes
an HTML highlighted version of it to
standard output. Note that all it does is generate a block of
<code> [...] </code>
HTML tags, no HTML headers.
Note:
This option does not work together with the -r
option.
|
-v |
--version |
Example #6 Using -v to get the SAPI
name and the version of PHP and Zend
$ php -v
PHP 5.3.1 (cli) (built: Dec 11 2009 19:55:07)
Copyright (c) 1997-2009 The PHP Group
Zend Engine v2.3.0, Copyright (c) 1998-2009 Zend Technologies
|
-w |
--strip |
Display source with comments and whitespace stripped.
Note:
This option does not work together with the -r
option.
|
-z |
--zend-extension |
Load Zend extension. If only a filename is given, PHP tries to load
this extension from the current default library path on your system
(usually /etc/ld.so.conf on Linux systems, for
example). Passing a filename with an absolute path will
not use the system's library search path. A relative filename including
directory information will tell PHP to try
loading the extension relative to the current directory.
|
|
--ini |
Show configuration file names and scanned directories.
Example #7 --ini example
$ php --ini
Configuration File (php.ini) Path: /usr/dev/php/5.2/lib
Loaded Configuration File: /usr/dev/php/5.2/lib/php.ini
Scan for additional .ini files in: (none)
Additional .ini files parsed: (none)
|
--rf |
--rfunction |
Show information about the given function or class method (e.g.
number and name of the parameters).
This option is only available if PHP was compiled with
Reflection support.
Example #8 basic --rf usage
$ php --rf var_dump
Function [ <internal> public function var_dump ] {
- Parameters [2] {
Parameter #0 [ <required> $var ]
Parameter #1 [ <optional> $... ]
}
}
|
--rc |
--rclass |
Show information about the given class (list of constants, properties
and methods).
This option is only available if PHP was compiled with
Reflection support.
Example #9 --rc example
$ php --rc Directory
Class [ <internal:standard> class Directory ] {
- Constants [0] {
}
- Static properties [0] {
}
- Static methods [0] {
}
- Properties [0] {
}
- Methods [3] {
Method [ <internal> public method close ] {
}
Method [ <internal> public method rewind ] {
}
Method [ <internal> public method read ] {
}
}
}
|
--re |
--rextension |
Show information about the given extension (list of php.ini options,
defined functions, constants and classes).
This option is only available if PHP was compiled with
Reflection support.
Example #10 --re example
$ php --re json
Extension [ <persistent> extension #19 json version 1.2.1 ] {
- Functions {
Function [ <internal> function json_encode ] {
}
Function [ <internal> function json_decode ] {
}
}
}
|
--rz |
--rzendextension |
Show the configuration information for the given Zend extension (the
same information that is returned by phpinfo()).
|
--ri |
--rextinfo |
Show the configuration information for the given extension (the same
information that is returned by phpinfo()).
The core configuration information
is available using "main" as extension name.
Example #11 --ri example
$ php --ri date
date
date/time support => enabled
"Olson" Timezone Database Version => 2009.20
Timezone Database => internal
Default timezone => Europe/Oslo
Directive => Local Value => Master Value
date.timezone => Europe/Oslo => Europe/Oslo
date.default_latitude => 59.930972 => 59.930972
date.default_longitude => 10.776699 => 10.776699
date.sunset_zenith => 90.583333 => 90.583333
date.sunrise_zenith => 90.583333 => 90.583333
