I am glad to hear someone else is interested in php.cli improvements.
I have written an extension to Gnu Make which enables using sapi/cli/php in
a makefile environment with auto-detection of dependencies. See:
http://www.xmake.org
I have previously posted twice on the subject of a -M switch (similar to
gcc -M), for enabling proper use of sapi/cli/php in a makefile environment
- I got no responses.
Here is the proposal:
* Add a '-M' option to sapi/cli/php that would behave essentially the same
as gcc -M and enable the use of php command-line scripts to work properly
in a makefile build environment (See below for explanation of gcc -M).
* 'php -M -f myFile.php' should differ from 'gcc -M myFile.c', in two ways:
a) Command output should only list prerequisite files rather than
a complete dependency makefile rule since there is no standard suffix for
php output as for C [ myFile.o : myFile.c ... ]
b) Detect dependencies other than included and required files, as
reported by get_included_files(). There are many other ways that a PHP
script could become dependent on other files which cannot easily be
determined automatically unless a function is available for a script to
explicitly declare that it depends on an external file. [Example: ? if
(file_exists($myFile)) echo hello;?].
* Add two built-in PHP functions to allow '-M' option to accurately
identify file dependencies in PHP source files (the names could change):
void register_prerequisite_file( string $myFile )
Array get_prerequisite_files( )
* With the above two functions, this is how the system should work:
In the following example, /usr/local/bin/php-cli is the command-line
version of PHP: sapi/cli/php
- file: test.php
#!/usr/local/bin/php-cli
?
php include( myIncludedFile.php );
register_prerequisite_file( myRequiredFile)
if (file_exists( myRequiredFile )) echo got file;
?
eof
Internally php-cli -M would call get_included_files() and
get_prerequisite_files() and join them together in a space separated list,
with the first item being the source file. Here is what php-cli would do
from the command line:
$/usr/local/bin/php-cli -M -f test.php
test.php myIncludedFile.php myRequiredFile
---
# example makefile which implements the functionality without php -M
# Command for generating output files from source files
# the command-line version of php binary must be specified in:
XME_php.cli_outfileCmd
# this is built under php_source_dir/sapi/cli/php
XME_php.cli_outfileCmd:=/usr/local/bin/php
# Command to generate a list of dependencies from a source file (including
the source file)
# $(1) - source file
define XME_php.cli_dependCmd
$(shell $(XME_php.cli_outfileCmd) -r 'include $(1); $$tmpFile =
$(XMAKE_TMP_DIR)/php.cli_dependCmd_out; if
(function_exists('get_prerequisite_files')){ $$files =
get_prerequisite_files();}else{$$files = get_included_files();} $$str =

$(XMAKE_TMP_DIR)/php.cli_dependCmd_junk; exit 1; }; cat
$(XMAKE_TMP_DIR)/php.cli_dependCmd_out; )
endef
# end of makefile
Below is what the include file looks like
?php

[PHP-DEV] PROPOSAL: sapi/cli/php -M (similar to gcc -M)
I have recenlty posted on this topic but got no response, probably because
I didn't phrase it well.
I would like to implement this proposed feature if I can get some feedback
to know if it would be accepted for inclusion.

define phpDependencies
$(shell $(PHP) -M -f $(1))
endef
myFile.html : $(call phpDependencies,myFile.php)
$(PHP) -f $ $@ || { echo failed; cat $@; exit 1; }
# end of makefile
-- APPENDIX - For those unfamiliar with gcc -M, following if
from info gcc
`-M'
Tell the preprocessor to output a rule suitable for `make'
describing the dependencies of each object file. For each source
file, the preprocessor outputs one `make'-rule whose target is the
object file name for that source file and whose dependencies are
all the `#include' header files it uses. This rule may be a
single line or may be continued with `\'-newline if it is long.
The list of rules is printed on standard output instead of the
preprocessed C program.
`-M' implies `-E'.
Another way to specify output of a `make' rule is by setting the
environment variable `DEPENDENCIES_OUTPUT' (*note Environment
Variables::.).
`-E'
Run only the C preprocessor. Preprocess all the C source files
specified and output the results to standard output or to the
specified output file.

[PHP-DEV] register_prerequisite_file( $myFile ); //or cli option to generate dependency list
I use php a lot to process php files in a makefile driven build environment I have written: xmake.org I think it would be nice to have an option to sapi/cli to generate a list of dependencies, like gcc -M get_included_files() is useful, but not sufficient since it only reports included or required files - any other dependencies are not detected, such as files opened by other means such as file(), file_exists(), I use the following macro in my makefile to generate a rule for the input source file $(1). # Command to generate a list of dependencies from a source file (including the source file) # $(1) - source file define XMakeExt_php.cli_dependCmd $(shell /usr/local/bin/php -r 'ob_start(); include $(1);ob_end_clean() ; $$files = get_included_files(); foreach($$files as $$file) echo $$file ;') endef I'd like to know what others think might be a good solution. I see two options: 1. give sapi/cli an option to auto-detect dependencies 2. Add a simple a function you could call to register a prerequisite file such as: ?php register_prerequisite_file( $myFile ); // code follows which uses the file for something... $array=($myFile); ? I think PHP is a great tool for command line scripting but without dependency-detection, applications are limited. - Greg Keraunen http://www.xmake.org http://www.xmlmake.com -- PHP Development Mailing List http://www.php.net/ To unsubscribe, visit: http://www.php.net/unsub.php
[PHP-DEV] when PHP code causes crash due to bad input, is it a bug?
I am trying to help with PHP. But this experience makes me feel like it is not worth it. Can anyone give me some clarification. Is there a common agreement on what constitutes a bug? I have worked as Sr. SQA engineer for many years and have always worked under the understanding that crashes are unacceptible - no matter what caused them: code should be able to handle bad data and not crash.

I could not verify this bug, but I don't have the Oracle stuff here.
As this is a fairly old bug, could you please test 4.0.5 or a snapshot and see if you
still have the same problem?
