Pear error “XML Extension not found” on Ubuntu 14.04 after installing php-xml & php-xml7.0

Question 1

I wanna use the pecl command to install redis to my php on Ubuntu 14.04. But my Pear is giving me a list of warnings:

XML Extension not found

Last line gives me this message

XML Extension not found

, although I installed #sudo apt-get install php-xml php7.0-xml. But the same problem still occurs.

What could be the problem?

Question 2

On some installations, there is a bug in pecl. Find this line;

exec $PHP -C -n -q $INCARG -d date.timezone=UTC -d output_buffering=1 -d variables_order=EGPCS -d safe_mode=0 -d register_argc_argv="On" $INCDIR/peclcmd.php "$@"

remove the -n

If you want to script it, try:

sed -i "$ s|-n||g" /usr/bin/pecl

Question 3

Whoa, why are you installing PDO from PECL? PDO has been built in to PHP since 5.1. Are you running 5.0?

If you're running 5.1 or higher and are missing PDO, chances are that:

Your copy of PHP was compiled without it, and must be recompiled; or
Your copy of PHP was installed from your OS's repository without the PDO module

If 1, you'll need to either recompile PHP from scratch, or compile just the shared module and copy it to the correct location.

If 2, you'll just need to install your OS's PDO extension. Under RHEL and CentOS, try yum search php-pdo. I don't know the proper syntax for calling the package installer for other distros, but the package will almost certainly include the string "php-pdo". (Tip: If you got your PHP from your OS, they also might provide common PECL packages. Try searching for "pecl" in their repositories.)

Finally, if you're running 5.0... for the sake of all that is good in this world, upgrade! Read through the upgrade notes in the PHP manual first, just in case you're using old behavior by accident.

(Also, to reconfigure pecl, try pecl config-show to see what settings are available, followed by a pecl config-set ... to change a setting. Do not try to install the PDO extension for a version of PHP newer than 5.0.x, it will break. There's even a big fat box at the top of the PDO page on the PECL site.)

Question 4

Looks you did not install DB package, try in command prompt, do

pear list

If no package of DB is installed, you can installed it with

pear install DB

example from documentation

Question 5

Code should be

<?php

    #FileName = "Connection_php_mysql.htm"
    #Type = "MYSQL"
    #HTTP = "true"

    $hostname_Main_DB = "localhost";
    $database_Main_DB = "mydb";
    $username_Main_DB = "root";
    $password_Main_DB = "";

    $con = mysqli_connect($hostname_Main_DB,$username_Main_DB,$password_Main_DB, $database_Main_DB) or die ( "Failed to connect to MySQL: " . mysqli_connect_errno());

    $db=mysqli_select_db($database_Main_DB,$con) or die( "Failed to connect to MySQL: ".mysqli_connect_errno());
?>

You should remove "new". For more information read this

Edit :-

Also you have added . in between two variable that should be ,

$username_Main_DB. $password_Main_DB replace this with $username_Main_DB,$password_Main_DB

Question 6

The pkgconfig command gives you all of the necessary -I (include) and -l (linker) statements for the compiler, when including a certain package.

Take a look what is given by running:

pkgconfig --cflags --libs gtk+-2.0

I've tried compiling your code on my Ubuntu 14.04.1 and it went fine, when I used:

g++ main.cpp `pkg-config --cflags --libs gtk+-2.0`

Probably pkg-config --libs --cflags glib-2.0 wasn't enough to provide all of the necessary include paths and shared libraries.
