I am having this error while installing pecl/amqp

when I type in the command line: pear install pecl/amqp

WARNING: php_bin C:\xampp\php.\php.exe appears to have a suffix .\php.exe,

but

config variable php_suffix does not match
ERROR: The DSP amqp.dsp does not exist.

I need to install this so that I can use amqp (RabbitMQ) on php.

php rabbitmq pear amqp pecl
