Exuberant Ctags on Mac - php

I'm currently using vim for my PHP development. A few weeks ago I bought myself a mac, and wanted to re-generate my tags for a new Zend Framework version.
I used the following script in the past (linux machine) to generate the tags:
#!/bin/bash
cd ~/www/ZF/
ctags-exuberant -f ~/.vim/tags/zend \
-h ".php" -R \
--exclude="\.svn" \
--totals=yes \
--tag-relative=yes \
--PHP-kinds=+cf \
--regex-PHP='/abstract class ([^ ]*)/\1/c/' \
--regex-PHP='/interface ([^ ]*)/\1/c/' \
--regex-PHP='/(public |static |abstract |protected |private )+function ([^ (]*)/\2/f/'
You can see I used the "ctags-exuberant" command. The problem is that this isn't found on my system (mac). I only have the ctags command. I tried installing the newest version of the ctags library (http://ctags.sourceforge.net/) but didn't gave me that command.
The ctags command does not have the same parameters as the ctags-exuberant. So 2 questions:
What's the difference between the 2 commands?
How can I install ctags-exuberant or use the normal ctags command for PHP?
Thanks!

Install Homebrew, then do:
brew install ctags

Install MacPorts, then do:
port install ctags

For a more friendly way to do this instead of using mac-ports or homebrew and running the risk of causing errors download ctags from here and compile with xcode (starting with version 4.3 command line tools are not installed by default but rather through Preferences -> Downloads) then simply move the compiled ctags to /usr/bin/ctags-exuberant to preserve the original.
Commands Used:
Change Directory to Downloads and ctags directory:
$cd$cd Down<tab>ctags<tab>
Configure:
$./configure
Make:
$make
Move to /usr/bin:
$sudo mv ctags /usr/bin/ctags-exuberant
NOTE: <tab> is equal to pressing the tab key.NOTE: XCode can now be downloaded from the Apple App Store!
Very useful for getting Tagbar for vim to work!
Tagbar is available here.

Trying to upgrade SQLite on Amazon EC2

I need SQLite minimum version 3.8 to support a MediaWiki install on Amazon EC2. Amazon Linux is based on CentOS and the latest version available in the yum repository is SQLite 3.7.17.
The downloads available from sqlite.org don't include 64-bit Linux. There is a GitHub repository that has a prebuilt 64-bit version, however it's only the command line version. I put it at /usr/bin:
$ which sqlite3
/usr/bin/sqlite3
$ sqlite3 --version
sqlite3: /lib64/libtinfo.so.5: no version information available (required by sqlite3)
3.26.0 2018-12-01 12:34:55 bf8c1b2b7a5960c282e543b9c293686dccff272512d08865f4600fb58238b4f9
But MediaWiki still complains I have SQLite 3.7.17 installed. When I test it I get:
$ cat x.php
<?php
print_r(SQLite3::version());
?>
Run it:
$ php7 x.php
Array
(
[versionString] => 3.7.17
[versionNumber] => 3007017
)
I am guessing this is because of these libraries:
$ sudo find / -name "libsqlite*"
/usr/lib64/libsqlite3.so.0
/usr/lib64/libsqlite3.so.0.8.6
How can I download/rebuild or otherwise install a later version of these SQLite libraries?
The easiest option I found was to build it myself. Tested on Amazon Linux release 2 (Karoo).
Download the latest source code with the configure script from here. Currently this is:
curl https://www.sqlite.org/2020/sqlite-autoconf-3320300.tar.gz | tar xzf -
Go into the created directory and create the Makefile with our system dependant options:
cd ./sqlite-autoconf-3320300 && ./configure
Build the binary
make
Install it
sudo make install
Clean up
cd .. && rm -r ./sqlite-autoconf-3320300
Note: It's far from ideal to do this without a proper RPM package. If you update sqlite through yum, you will overwrite you manually built version.
Adding on to #halbgut answer, with some changes:
Download the latest source code with the configure script from here. Currently this is:
curl https://www.sqlite.org/2020/sqlite-autoconf-3320300.tar.gz | tar xzf -
Go into the created directory and create the Makefile with our system dependent options:
cd ./sqlite-autoconf-3320300 && ./configure
Build the binary
make
Install it
sudo make install
Now, you have created the sqlite3 file. You need to replace them everywhere you find the file sqlite3.
To find all these places - run the following command:
whereis sqlite3
sqlite3: /usr/bin/sqlite3 /usr/local/bin/sqlite3 /usr/include/sqlite3.h /opt/c9/bin/sqlite3 /usr/share/man/man1/sqlite3.1.gz
Now within the sqlite source folder ./sqlite-autoconf-3320300, find the sqlite3, sqlite3.h files and replace with the following cp command
sudo cp sqlite-autoconf-3320300/sqlite3 /usr/local/bin/sqlite3
sudo cp sqlite-autoconf-3320300/sqlite3 /usr/local/bin/sqlite3
sudo cp sqlite-autoconf-3320300/sqlite3 /opt/c9/bin/sqlite3 {I am using c9, hence this file, figure out what file is in the opt/ dir)
sudo cp sqlite-autoconf-3320300/sqlite3.h /usr/include/sqlite3.h
Once done, you would have upgraded both env and python-env. Now you need to just define the path to it. For it, use the local/lib in usr.
export LD_LIBRARY_PATH="/usr/local/lib"
Now you should have this :
$ python -c "import sqlite3; print(sqlite3.sqlite_version)"
3.23.3
$ sqlite3 --version
3.32.3
If you just need the sqlite3 binary, the SQLite amalgamation also works perfectly on Amazon Linux 2. For SQLite 33.9.04 (or others from the SQLite Download section):
wget "https://www.sqlite.org/2022/sqlite-amalgamation-3390400.zip"
unzip "sqlite-amalgamation-3390400.zip"
cd "sqlite-amalgamation-3390400"
gcc shell.c sqlite3.c -lpthread -ldl -lm -o sqlite3
And then use it as you would any other software compiled from source:
ln -n ./sqlite3 ${wherever}/sqlite3
export PATH="${wherever}:$PATH"
SQLite docs give a good explanation of further options if you need them.
Get the latest sqlite3 download link from https://www.sqlite.org/download.html
and update the link given in the WGET bash command example shown below.
Example:
wget https://www.sqlite.org/2022/sqlite-tools-linux-x86-3400000.zip
unzip sqlite-tools*.zip
cd sqlite-tools*
sudo cp sql* /usr/local/bin/ # Usually this directory is empty, so no need to worry about overwriting files
cd ~
sudo yum update -y
sudo amazon-linux-extras install epel -y
sudo yum install glibc.i686 -y
sqlite3 --version

PHP extension not built with same debug and thread safe as PHP

I built a number of custom PHP extensions under windows 8-10 years ago. I made the move to Ubuntu Linux for all of my web stuff some years ago and find I need to create another custom extension. I'll be doing the development under Ubuntu this time.
I've created a very simple extension (a no-op actually) just to make sure I have the build process working. It's not.
Here is what I have done:
Cloned PHP from Git
Checked out PHP-5.5
Configured with --disable-all --enable-debug --enable-maintainer-zts \
--prefix=
Build PHP
Success php -i shows:
Zend Extension Build => API220121212,TS,debug
PHP Extension Build => API20121212,TS,debug
Created ext/a1 for my new, very simple extension
Created the basic extension (from Sara Goleman's book)
Ran phpize in ext/a1
Ran ./configure --enable-a1
Ran make
Build was successful.
Copied a1.so to the extensions directory
phpdir/bin/php -dextension=a1.so -v
Fails. Results in:
Module compiled with build ID=API20121212,NTS
PHP compiled with build ID=API20121212,TS,debug
So. Color me confused. According to what I've read, the phpize command is supposed to match the extension build settings to the php build settings.
I've apparently missed something basic here somewhere.
Help will be most appreciated.
Its hard to say what exactly was going wrong, I can only say that the extension was build using a different config than the php version.
I will describe some reproducible steps how to compile a most basic extension with debug symbols within the PHP source folder. The extension contains no code except of some boilerplate code created by ext_skel. It just describes the compilation process on UNIX. It is a shell script, you might execute it.
#!/bin/sh
# Should work for all PHP5 versions
VERSION="5.6.9"
# Download the PHP source code
wget \
--continue "http://de2.php.net/get/php-$VERSION.tar.gz/from/this/mirror" \
-O "php-$VERSION".tar.gz
tar xf "php-$VERSION.tar.gz" && cd "php-$VERSION/ext"
# Create a hello extension from skeletons
./ext_skel --extname="hello"
# Uncomment two lines in ext/hello/config.m4
# Read the comments there and you'll know what I'm doing
sed -ri.original \
-e 's/(dnl )(PHP_ARG_ENABLE\(hello)/\2/' \
-e 's/(dnl )(\[ --enable-hello)/\2/' \
hello/config.m4
# Build PHP and the extension
cd ..
./buildconf --force
./configure \
--enable-debug --enable-maintainer-zts \
--enable-hello=shared
make -j
# Test if it is working
sapi/cli/php \
-dextension=modules/hello.so \
-r 'var_dump(extension_loaded("hello"));'
You can now start to enter code to ext/hello/hello.c and create your extension. If you want to compile the changes you make just issue make without arguments.
Since we've compiled using --debug we you can now use gdb to debug the C code and explore how PHP internally works. To start a debugging session use:
gdb sapi/cli/php
...
(gdb) break main
(gdb) run -dextension=modules/hello.so some.php
Of course you'll mostly set breakpoints into your extension functions rather than in the php main() function once you've added code to the extension. However, this should show the basic steps to get there.
Have fun! :)

Upgrading PHP in XAMPP for linux?

How can I upgrade my current php (only) in xampp?
I need to upgrade from 5.3.1 to 5.4.0
Download PHP's source code and extract it in /usr/src:
cd ~/downloads
wget http://snaps.php.net/php5.4-latest.tar.gz
tar -xzf php5.4-latest.tar.gz
sudo mv php5.4 /usr/src/php-5.4
You need to find the configuration of already installed version , so you can use it and install the new version with the exact same configuration
/opt/lampp/bin/php --info | grep "Configure Command"
You should see something like this as result :
./configure '--prefix=/opt/lampp' '--with-apxs2=/opt/lampp/bin/apxs' '--with-config-file-path=/opt/lampp/etc' '--with-mysql=mysqlnd' '--enable-inline-optimization' '--disable-debug'
Actually, list should probably be much more longer. Copy and store it as you will need to use it as a whole later.
Make a backup of the current installation, in case if anything goes wrong
sudo cp -r /opt/lampp /opt/lampp.bak
Now that you have configuration options, review it and then use it to compile the new version.
cd /usr/src/php-5.4/
./configure --prefix=/opt/lampp --with-apxs2=/opt/lampp/bin/apxs --with-config-file-path=/opt/lampp/etc --with-mysql=mysqlnd --enable-inline-optimization --disable-debug
make
make install
Run /opt/lampp/bin/php -v in order to make sure you have correct php version installed. It should be 5.4.0 Beta.
Just want to complement #altern answer....
When I tried all the indications exactly in line of
make install
I had an error in the output
Installing PHP SAPI module: apache2handler
/opt/lampp/build/instdso.sh SH_LIBTOOL='/opt/lampp/build/libtool' libphp7.la /opt/lampp/modules

libtool: install: you must specify an install program
libtool: install: Try `libtool --help --mode=install' for more information.

After looking for information to solve, I found a japanese link:
http://d.hatena.ne.jp/Kenji_s/touch/searchdiary?word=*%5BUbuntu%5D
What I did to solve it after trying to understand this japanese solution was simply:
sudo nano /opt/lampp/build/libtool
And when the editor was opened I changed the first line, instead of:
#! /bin/sh
I wrote:
#! /bin/bash
After that I tried again
make install
And voila it compiled!
Hope It helps someone
Now XAMPP is supporting PHP 5.4 and PHP 5.5. You can now download installer of your required version of PHP from http://www.apachefriends.org/en/xampp-linux.html
Thanks.

How do I install Pdftk on my server?

I am using a Linux Server and am trying to install Pdftk, but I am problems trying to figure out what exactly to do.
I found the following documentation on how to install it, but they refer mostly to installing it on the local Windows machine.
They are:
http://www.andrewheiss.com/blog/2009/07/29/installing-pdftk-php/
http://www.accesspdf.com/pdftk/#packages
Can someone help me unserstand exactly what files I need to place where on my server so I can refer to pdftk?
Pdftk is a version of iText which has been converted from Java to c++ and rebuilt with a command-line bridge for easy access from PHP applications.
To build pdftk on Redhat / CentOS please follow the below instructions.
ssh [server to install pdftk on]
Now that we are in the server we need to create the directories to store pdftk.
cd /
sudo mkdir extra
cd extra
sudo mkdir src
cd src
sudo wget http://www.pdfhacks.com/pdftk/pdftk-1.41.tar.gz
sudo tar zxvf pdftk-1.41.tar.gz
cd pdftk-1.41/pdftk
Now we need to install the gcj libraries.
sudo yum install java-1.4.2-gcj-compat-devel.i386
The gcc-c++ library doesn't get installed with the gcj package so we will install it now, so we don't get an error halfway through the compile process.
sudo yum install gcc-c++
If you compile the application right now you will receive a warning that tmpnam is dangerous to use and you should use mkstemp.
sudo vi report.cc
Run this from inside VI to do a search and replace for the tmpnam method.
:%s/tmpnam(/mkstemp(/g
Press escape and save the changes with
:wq!
Now that we have all the packages installed, we are going to start compiling pdftk-1.41
from /extra/src/pdftk-1.41/pdftk run the following command
sudo make -f Makefile.RedHat
This will kick off the build process for compiling and converting the java file to c++. This could take SEVERAL minutes to convert iText to c++. Go grab yourself a margarita from our new margarita machine in the break room :).
Now with the pdftk file created we will want to copy it to the /bin directory so that we can run it from anywhere.
sudo cp pdftk /usr/local/bin
Let's make sure the build was successful and run
pdftk --version
As of 2020, things are different now. CentOS 6 is stepping out and pdftk can only support CentOS 5/6. GCJ on CentOS 7 is removed, so installing from source is not easy too. But we have docker now:
FROM centos:centos6
RUN yum install -y https://www.pdflabs.com/tools/pdftk-the-pdf-toolkit/pdftk-2.02-1.el6.x86_64.rpm
Then build with docker build . -t pdftk and run as:
docker run -it --rm -v $PWD:/data --workdir /data pdftk pdftk ./input.pdf output ./output.pdf
The example above can repair a pdf file missing a dozen of KB of data if you are lucky.
As mentioned by #rsc, pdftk-java will be available for Rocky Linux, but currently (2021.10.28), still cannot install it via yum.
Fortunately, there is a built command for x86_64 GNU/Linux systems, which does not require any runtime dependencies. So we can use it as follows
# the version number might be updated, check https://gitlab.com/pdftk-java/pdftk
wget https://gitlab.com/pdftk-java/pdftk/-/jobs/1527259632/artifacts/raw/build/native-image/pdftk
chmod +x pdftk
./pdftk ...
It works well in the server with the following system info,
$ lsb_release -a
LSB Version: :core-4.1-amd64:core-4.1-noarch
Distributor ID: Rocky
Description: Rocky Linux release 8.4 (Green Obsidian)
Release: 8.4
Codename: GreenObsidian
As of 2021, there is pdftk-java: A port of the original GCJ-based PDFtk to Java, which is currently on the way to the repositories for Fedora 33+ and EPEL 7+ (latter for CentOS, RHEL or Rocky), allowing yum install pdftk-java to succeed (once the package reached the stable repositories).
Edit: The pdftk-java package is in the stable repositories since yesterday, 2021-10-29.

How to install php-gtk in the Acer Aspire One?

I have an application that works pretty well in Ubuntu, Windows and the Xandros that come with the Asus EeePC.
Now we are moving to the Acer Aspire One but I'm having a lot of trouble making php-gtk to compile under the Fedora-like (Linpus Linux Lite) Linux that come with it.
I managed to get all components needed for Phoronix test suite installed on Fedora but still have one issue.
# phoronix-test-suite gui
shell-init: error retrieving current directory: getcwd: cannot access parent directories: No such file or directory
pwd: error retrieving current directory: getcwd: cannot access parent directories: No such file or directory
pwd: error retrieving current directory: getcwd: cannot access parent directories: No such file or directory
/usr/bin/phoronix-test-suite: line 28: [: /usr/share/phoronix-test-suite: unary operator expected
You need two packages that aren't in Fedora, php-gtk, but php-gtk also has it's dependency - pecl-cairo
php-gtk needs to be downloaded from svn because tar.gz version is really old and doesn't work with php 5.3
Here is how I got all components built.
su -c "yum install php-cli php-devel make gcc gtk2-devel svn"
svn co http://svn.php.net/repository/pecl/cairo/trunk pecl-cairo
cd pecl-cairo/
phpize
./configure
make
su -c "make install"
cd ..
svn co http://svn.php.net/repository/gtk/php-gtk/trunk php-gtk
cd php-gtk
./buildconf
./configure
make
su -c "make install"
cd ..
wget http://www.phoronix-test-suite.com/download.php?file=phoronix-test-suite-2.8.1
tar xvzf phoronix-test-suite-2.8.1.tar.gz
cd phoronix-test-suite
su -c "./install-sh"
So please take where I left to get Phoronix test suite running on Fedora.
Hi Guys well I finally got this thing to work the basic workflow was this:
#!/bin/bash
sudo yum install yum-utils
#We don't want to update the main gtk2 by mistake so we download them
#manually and install with no-deps[1](and forced because gtk version
#version of AA1 and the gtk2-devel aren't compatible).
sudo yumdownloader --disablerepo=updates gtk2-devel glib2-devel
sudo rpm --force --nodeps -i gtk2*rpm glib2*rpm
#We install the rest of the libraries needed.
sudo yum --disablerepo=updates install atk-devel pango-devel libglade2-devel
sudo yum install php-cli php-devel make gcc
#We Download and compile php-gtk
wget http://gtk.php.net/do_download.php?download_file=php-gtk-2.0.1.tar.gz
tar -xvzf php-gtk-2.0.1.tar.gz
cd php-gtk-2.0.1
./buildconf
./configure
make
sudo make install
If you want to add more libraries like gtk-extra please type ./configure -help before making it to see the different options available.
After installing you'll need to add php_gtk2.so to the Dynamic Extensions of /etc/php.ini
extension=php_gtk2.so

If you could give us more to go on than just trouble making it compile; we might be better able to help you with your issues.
