how to install php amqp in ubuntu

Let's make life easier, follow these 2 steps, and that's all:

1. apt install php7.4-amqp (it depends on your php version)
2. Then add under the path of php.ini the following line extension = 'amqp.so'

You need to download the code for the PHP library from here: http://code.google.com/p/php-amqp/downloads/list

Then cd into that folder and run the command they tell you to run.

UPDATE: That page is actually an old page, they haven't updated it in a long time. You can grab the latest amqp from http://pecl.php.net/get/amqp:

wget http://pecl.php.net/get/amqp -O amqp.tar.gz
tar -zxvf amqp.tar.gz
cd amqp-1.0.7    # replace this with the current version
phpize
./configure --with-amqp
make
sudo make install

Then you'll need to add the following line to your php.ini file:

extension=amqp.so
