I try to make a custom php extension for code Encryption purposes,
I followed this tutorial to make an custom extension: How to make a PHP extension
i get this warning when compiling the extension:
WARNING
The following arguments is invalid, and therefore ignored:
--enable-php-helloworld
i did all according to the tutorial, i build on windows.
what are possible things i do wrong.
I followed that section: https://stackoverflow.com/a/32575493/3103078
I replicated the code 1:1 (Os: Windows)
used commands:
phpize
configure --enable-php-helloworld
nmake
php -d extension=php_helloworld.so --re php_helloworld
Expected result:
>>>helloworld support
Actual Result:
>>>

phpize

nmake
php -d extension=php_helloworld.so --re php_helloworld
The issue was not utilizing the php-src inside the sdk.
Also, on windows you need to use php-sdk-binary-tools, else it wont work when you compile it.
I'll do a tutorial on this soon.
When running composer diagnose, I get the following error :
The xdebug extension is loaded, this can slow down Composer a little.
Disabling it when using Composer is recommended.
How can I disable xdebug only when I'm running Composer?
Update: For Xdebug 3+:
As of Xdebug 3, it is possible to disable the Xdebug completely by setting the option xdebug.mode to off, or by setting the environment variable XDEBUG_MODE=off.
It is very easy to disable Xdebug just for composer, by aliasing composer.
alias composer='XDEBUG_MODE=off \composer'
OR
alias composer='php -dxdebug.mode=off $(where composer | fgrep -v composer: | head -1)'
You can add the alias to your $HOME/.bashrc to make it permanent.
Update: For Xdebug 1.3 - 3.0.0 :
The issue has been fixed in Composer 1.3. Update composer to the latest version by executing composer self-update, instead of trying the following workaround.
For Xdebug < 1.3
Here is my modification of #ezzatron's code. I have updated the script to detect ini files from phpinfo output.
#!/bin/sh
php_no_xdebug () {
temporaryPath="$(mktemp -t php.XXXX).ini"
# Using awk to ensure that files ending without newlines do not lead to configuration error
php -i | grep "\.ini" | grep -o -e '\(/[a-z0-9._-]\+\)\+\.ini' | grep -v xdebug | xargs awk 'FNR==1{print ""}1' | grep -v xdebug > "$temporaryPath"
php -n -c "$temporaryPath" "$#"
rm -f "$temporaryPath"
}
php_no_xdebug /usr/local/bin/composer.phar $#
# On MacOS with composer installed using brew, comment previous line
# Install jq by executing `brew install jq` and uncomment following line.
# php_no_xdebug /usr/local/Cellar/composer/`brew info --json=v1 composer | jq -r '.[0].installed[0].version'`/libexec/composer.phar $#
This command will disable the PHP5 Xdebug module for CLI (and thus composer) :
sudo php5dismod -s cli xdebug
It removes the xdebug.ini symlink from /etc/php5/cli/conf.d/
This was suggested on http://blog.lorenzbausch.de/2015/02/10/php-disable-xdebug-for-cli/
Note that for Ubuntu 16.04 you probably need to run it like this:
sudo phpdismod -s cli xdebug
I don’t think there is an option to configure PHP so it can load different configurations according to the targeted script. At least, not without duplicating .ini files...
However, you can add thoses options when running composer with php:
php -n -d extension=needed_ext.so composer.phar
-n will tell PHP to ignore any php.ini. This will prevent xdebug from loading for this very command.
-d options permits you to add any option you want (for exemple, activate needed_ext.so). You can use multiple -d options. Of course, this is optional, you might not need it.
Then you can create an alias, to make it sugary again.
A typical solution (because composer needs json):
php -n -d extension=json.so composer.phar
greg0ire > my solution, based on that:
#!/bin/bash
options=$(ls -1 /usr/lib64/php/modules| \
grep --invert-match xdebug| \
# remove problematic extensions
egrep --invert-match 'mysql|wddx|pgsql'| \
sed --expression 's/\(.*\)/ --define extension=\1/'| \
# join everything together back in one big line
tr --delete '\n'
)
# build the final command line
php --no-php-ini $options ~/bin/composer $*
alias composer=/path/to/bash/script.sh
It looks ugly (I tried and failed to do that with xargs), but works… I had to disable some extensions though, otherwise I get the following warnings:
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/mysqli.so' - /usr/lib64/php/modules/mysqli.so: undefined symbol: mysqlnd_connect in Unknown on line 0
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/pdo_mysql.so' - /usr/lib64/php/modules/pdo_mysql.so: undefined symbol: pdo_parse_params in Unknown on line 0

You can disable Xdebug setting an environment variable:
XDEBUG_MODE=off composer install
It's available using XDebug 3.
By creating an alias you'll suppress that composer xdebug error message.
Just add this line to your ~/.bash_aliases within your system and it should work flawlessly.
alias composer="php -n /usr/local/bin/composer"
Reload the shell to make the new alias composer available.
source ~/.bash_profile
USAGE:
$ composer --version
NOTE:
You don't necessarily need to use any other parameter.
Depending on your system you might have a .bashrc instead of .bash_profile.
UPDATE:
As #AlexanderKachkaev mention in the comments it's worth nothing to add the memory_limit as follows to avoid crashing im some situations:
alias composer="php -d memory_limit=-1 -n /usr/local/bin/composer"
I came up with an answer that works pretty well for OSX, and could probably be adapted for any PHP version that loads its extensions using individual .ini files in the "additional ini dir":
#!/bin/sh
function php-no-xdebug {
local temporaryPath="$(mktemp -t php-no-debug)"
find /opt/local/etc/$1/php.ini /opt/local/var/db/$1/*.ini ! -name xdebug.ini | xargs cat > "$temporaryPath"
php -n -c "$temporaryPath" "${#:2}"
rm -f "$temporaryPath"
}
alias composer="php-no-xdebug php56 ~/bin/composer"
I usually create a shell script per project, since every project has another PHP version. It's in a /bin/ directory next to composer.phar and composer.json and I run it as ./bin/composer in my project directory.
It looks like this (for php56)
#!/bin/sh
DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"
COMPOSER_DISABLE_XDEBUG_WARN=1 /opt/local/bin/php56 \
-d xdebug.remote_enable=0 -d xdebug.profiler_enable=0 \
-d xdebug.default_enable=0 $DIR/../composer.phar "$#"
The -d options effectively disable xdebug. The COMPOSER_DISABLE_XDEBUG_WARN=1 part disables the warning composer issues.
Disabling the xdebug extension is preferred (see composer troubleshooting), but I personally like the simpler script.
Some timings on my machine:
2
Run with xdebug and ini-enabled: 1m33
Run with xdebug but ini-disabled: 0m19
Run without xdebug: 0m10
If you use PHPStorm, the latest release (2016.2) comes with a feature to enable XDebug for CLI scripts on-demand, which means you can simply turn off XDebug globally on your development machine. The IDE will enable it on the fly when it is needed by code inside your projects.
https://blog.jetbrains.com/phpstorm/2016/06/xdebug-on-demand-for-cli-php-scripts-in-phpstorm-2016-2-eap/
PhpStorm 2016.2 introduces Xdebug On Demand mode where you can disable Xdebug for your global PHP install, and PhpStorm will only enable it when it needs to — when you’re debugging your scripts, or when you need code coverage reports.
You need to edit your PHP Interpreters preferences to include the path to XDebug, as described in the linked article.
To me this seems like the perfect solution, as I only usually want XDebug while I'm in the IDE.
However XDebug does have other potential uses when you are "offline" e.g. extended stack dumps in error logs, which you would lose by turning it off globally. Of course you shouldn't have XDebug enabled on production, so this would be limited to use cases like beta-testing or automated-testing CLI scripts in development.
Rather than muddle with temporarily enabling or disabling the PHP module, when you might have concurrent processes using PHP (for example as part of a CI pipeline), you can tell PHP to point at a different module loading directory.
While this is similar to some of the solutions mentioned above, this solves a few edge cases, which is very useful when being used by Jenkins or other CI runner which runs tests on the same machine concurrently.
The easiest way to do this is to use the environment variable PHP_INI_SCAN_DIR
Using this in a script or build task is easy:
export PHP_INI_SCAN_DIR=/etc/php.d.noxdebug
php composer install
Of course you would want to prepare /etc/php.d.noxdebug first, doing something like:
mkdir /etc/php.d.noxdebug
cp /etc/php.d/* /etc/php.d.noxdebug
rm /etc/php.d.noxdebug/xdebug.ini
This means you have an environment similar to the old php environment, with only one module missing. Meaning you don't need to worry about needing to load the phar/json modules as you would with the php -n solution.
Direct manipulation of PHP config
Here's my contribution based on a Homebrew-installed PHP installation on Mac OS X.
It's a shell-script wrapper, designed to be saved as an executable file at /usr/local/bin/composer, with the Composer binary at /usr/local/bin/composer.phar:
#!/bin/sh
sed -i '' -e 's:zend_extension="/usr/local/opt/php55-xdebug/xdebug.so":;zend_extension="/usr/local/opt/php55-xdebug/xdebug.so":' /usr/local/etc/php/5.5/conf.d/ext-xdebug.ini
/usr/local/bin/php /usr/local/bin/composer.phar "$#"
sed -i '' -e 's:;zend_extension="/usr/local/opt/php55-xdebug/xdebug.so":zend_extension="/usr/local/opt/php55-xdebug/xdebug.so":' /usr/local/etc/php/5.5/conf.d/ext-xdebug.ini
Theory of Operation
The wrapper script:
uses sed to temporarily modify the configuration file, disabling Xdebug (line 2)
executes Composer, passing through args to the command (line 3)
uses sed to restore the configuration file, re-enabling Xdebug (line 4)
The script is coupled to an OS X/Homebrew installation of PHP 5.5. The paths should be adjusted to work with other PHP versions and other operating systems' and package managers' directory layouts. Note also that some versions of sed do not need the empty-string argument following the -i option.
Caveat Utilitor
The script is straightforward, in that it works directly on the main PHP configuration files, however this is also a drawback: Xdebug will also be disabled for any scripts that happen to be executed concurrently with this script.
In my development environment, this is an acceptable trade-off, given that Composer is executed manually and only occasionally; however you may not want to use this technique if executing Composer as part of an automated deployment process.
I came up with a solution for the Windows-based Composer installer - it should work for any Composer installation, it just basically makes a copy of the loaded INI file and comments out the xdebug zend extension, then loads that configuration file when it runs composer.
I've opened an issue to see if they'd like to integrate this change:
https://github.com/composer/windows-setup/issues/58
You can find my instructions and code there.
As noted in Joyce's answer, this issue no longer exists in the latest version of Composer.
The Composer documentation has been updated to note this. It details how you can enable xdebug with Composer (if required).
You can update your version of Composer by utilising self-update.
On my Mac I had to do: sudo php /opt/local/bin/composer self-update
Further details about this in the context of a Homebrew PHP install can be found in this issue.
Creating an alias for composer to disable xdebug and prevent memory errors:
Add this line to your ~/.bash_profile
alias composer='php -d xdebug.profiler_enable=0 -d memory_limit=-1 /usr/local/bin/composer'
Restart the terminal to make the new alias available.
In most cases you do not need xdebug on CLI mode. If this is acceptable for you than you can configure cli and cgi differently.
So if you make php-cli.ini and conf-cli.d near exiting php.ini file than you can configure cli and cgi differently (for cgi it would be php.ini and conf.d). Just do not put xdebug.ini into conf-cli.d.
If you install composer using brew on OS X
You can use this alias:
alias composer="php -n $(cat $(which composer) | grep composer.phar | awk '{print $7}')"
My quick solution for a macports installation, with multiple versions of PHP was to write this simple shell wrapper for Composer:
/user/local/bin/composer-nodebug.sh
#!/bin/bash
sudo mv /opt/local/var/db/php53/xdebug.ini /opt/local/var/db/php53/xdebug.NOT
sudo mv /opt/local/var/db/php54/xdebug.ini /opt/local/var/db/php54/xdebug.NOT
sudo mv /opt/local/var/db/php55/xdebug.ini /opt/local/var/db/php55/xdebug.NOT
composer $1 $2 $3 $4 $5 $6 $7
sudo mv /opt/local/var/db/php53/xdebug.NOT /opt/local/var/db/php53/xdebug.ini
sudo mv /opt/local/var/db/php54/xdebug.NOT /opt/local/var/db/php54/xdebug.ini
sudo mv /opt/local/var/db/php55/xdebug.NOT /opt/local/var/db/php55/xdebug.ini
Then run any composer commands like so:
sudo composer-nodebug.sh update
Drawbacks:
requires sudo (unless you chmod the INI files)
if you kill it mid-way the INI files are modified
will require future PHP versions added.
while it's running other PHP processes are affected
Not elegant, but simple.
(Windows)
Based on documentation I use environment variable PHPRC, so I can choose which INI file shloud be loaded, thus I can choose whether I want to enable or disable Xdebug before executing a command (like composer install).
I have two INI files, one with Xdebug enabled (php-xdebug.ini) and one with Xdebug disabled (php.ini - it's also default one).
I use some batches (placed in location which is included in PATH environment variable, so it can be executed from anywhere):
To enable Xdebug I call xon.bat:
#ECHO OFF
set PHPRC=C:/path-to-php/php-xdebug.ini
To disable Xdebug I call xoff.bat:
#ECHO OFF
set PHPRC=
By calling php --ini I can check which INI file was loaded.
Alternatively you can use environment variable PHP_INI_SCAN_DIR in which you set a path to directory from where additional INI files will be loaded. Advantage is that you can load multiple INI files.
Here is my quick solution to get rid off the Xdebug warning on PHP5-cli version. I have removed the support of Xdebug for PHP5-cli on Ubuntu 14.04.
cd /etc/php5/cli/conf.d/
sudo rm 20-xdebug.ini
Now no more Xdebug warning on PHP5-cli.
I'm trying to get access to rename_function in PHP, and for that I need PECL APD. I'm running Ubuntu 14.04 LTS.
I'm trying to run sudo pecl install apd, but I'm getting:

This will be a short summary of everything to is a precondition to run APD as a PHP profiler, I hope it will help your needs. This summary applies for PHP 5.6.2 APD 1.0.1 and might be incorrect for other versions.
First of all do not start it if you didn't ensure these two:
Deactivate Zend platform or any other PHP optimizer. In general you need to disable all Zend extensions.
Install a debugging enabled version of PHP (--enable-debug)
If you have a working PEAR setup you need to setup APD like in this article. Don't forget to try out distribution packages either. Otherwise APD's build as following:
Extract tarball.
Change directory in tarball.
Run <apache root>/bin/phpsize
Run ./configure (Add --with-php-config=<apache root>/bin/php-config if configure fails.)
Compile and install everything using
make
make install
Edit php.ini and add at least
zend_extension=/apd.so
apd.statement=1
apd.tracedir=/tmp/apd-traces
Create the output directory specified in php.ini
Now you'll need to restart Apache but before you do, check that the APD extension works fine. To do simply run PHP
/bin/php
No warning should be given if extension is loaded properly. If you get error message something like the "apd.so" extension couldn't be loaded there is a problem. Check if you compiled against the correct Apache/PHP version and using the same right now.
If PHP doesn't complain about anything enter:
<?php phpinfo(); ?>
and check for some lines about APD. If you find them you are done.
You'll also need some traces so to start tracing you need to your Apache to allow the PHP module to load APD. Next you'll need to identify the script to trace. Add the APD call at the top of the script:
apd_set_pprof_trace();
Then make some requests and remove the statement again to avoid causing further harm.
Now have a look at the trace directory. You should find files with a naming scheme of pprof[0-9]*.[0-9] here. Decode them using the pprofp tool from your APD source tarball. Example:
/bin/php /pprofp -u
Redirect stdout if necessary. Use -t instead of -u (summary output) to get calling trees. When you create traces with -t you get a summary output too, but it doesn't contain the per-call durations. I suggest to always create both a call tree and a summary trace.
Hope that helps, I recommend you hardly to read the link mentioned above.
EDIT:
The phpize command is meant to be run at the top level of an extension source dir (this source dir should contain a file name config.m4). See this for more info.
As per error:
If the command failed with phpize: not found then you need to install php5-dev package.
You can do it by running apt-get install php5-dev as a root user
I think you should install module development for PHP via:
sudo apt-get install php5-dev
This should provide you with phpize binary necessary to compile the Pecl extension sources. And make sure it's in your PATH.
I am trying to run the 'phpize' command on MacOSx Mountain Lion, but this is what I get:
Cannot find config.m4.
Make sure that you run '/opt/local/bin/phpize' in the top level source directory of the module
How do I resolve this error ?
The phpize command is meant to be run at the top level of an extension source dir (this source dir should contain a file name config.m4).
See http://php.net/manual/en/install.pecl.phpize.php for more information.
In plain English, it means you're running the command from the wrong directory. You need to be in the directory that contains the source for the extension you're trying to install.
For example, if you're trying to install mcrypt, like I was when I came across this stack overflow page, you need to be in php-5.6.24/ext/mcrypt and then run the command.
My problem was that I was trying to execute the command just to see if I had it installed.
Trying to execute the command alone gives you that error, only use it inside the directory (most likely you downloaded) that contains the extension that you're trying to install.
Here some instructions to install Xdebug for php7.2 for example.
Take special care in step 3 and 4, first you change dir to the unpacked downloaded extension and then you run phpize.
http://qiita.com/MasatoYoshioka#github/items/e542f39a6f1a3bc1f71e
In terminal
ls config.m4
ls config*
config.w32 config0.m4
cp config0.m4 config.m4
cd /usr/local/src/php-5.3.29/ext/zlib
phpize
./configure
make clean && make && make install
nano php.ini
add extension=zlib.so
got inside the xdebug folder than try to run the phpize
Sometimes, using the pecl installer is not an option. This could be because you're behind a firewall, or it could be because the extension you want to install is not available as a PECL compatible package, such as unreleased extensions from git. If you need to build such an extension, you can use the lower-level build tools to perform the build manually.
The phpize command is used to prepare the build environment for a PHP extension. In the following sample, the sources for an extension are in a directory named extname:
$ cd extname
$ phpize
$ ./configure
$ make
# make install
first run ./configure it will create config.m4 file, rest the steps are same
I want to compile php sqlite3 with custom compile option. to do that I followed following steps
wget http://be.php.net/distributions/php-5.3.10.tar.gz
tar -xvf php-5.3.10.tar.gz
cd php-5.3.10/ext/sqlite3
Run phpize
But I am getting error:
Cannot find config.m4.
Make sure that you run '/usr/bin/phpize' in the top level source directory of the module
How can I solve this problem ?
