I have a GPS application that your manual is written for PHP 5, but I would like to use PHP 7.
I was able to install with no problem, but when I have to install PCNTL
I can not.
In PHP 5 the procedure is as follows:
apt-get install dpkg-dev
apt-get install php5-dev
mkdir /tmp/phpsource
cd /tmp/phpsource
apt-get source php5
cd /tmp/phpsource/php5-*/ext/pcntl
phpize
./configure
make
cp /tmp/phpsource/php5-*/ext/pcntl/modules/pcntl.so
/usr/lib/php5/20090626*/
But I do not know how to do this procedure in PHP 7.
