Problem Description:

[Root@localhost www]#/usr/local/php/bin/php index.php

PHP Fatal error:call to undefined function pcntl_fork() in/home/www/theard/threadprocessmanager.php in line 69 Solution:

1, the new compiler PHP

./configure--enable-pcntl "" "

2, do not reinstall also can, directly into your installation of PHP source directory ext/pcntl directory.

Run

Phpize

[Root@localhost pcntl]#./configure--with-php-config=/usr/local/php/bin/php-config && make && make Install

Put the generated files in the default directory:

[Root@localhost pcntl]# cp/usr/local/php/lib/php/extensions/no-debug-non-zts-20090626/pcntl.so/usr/lib/php/ modules/

And then add this extension to the php.ini.
Extension=pcntl.so
If you do not add it directly to your program (with the DL () function, the function will be canceled) can also, especially for PHP in addition to CmdLine and Apache do web work, because the Web service when loading Pnctl module love problems.

Test methods

test_fork.php:

?
echo "This is an echo before I called the fork command\n";

$pid = pcntl_fork();
if ($pid = = 1) {
Die ("Could not fork");
else if ($pid) {
echo "I am the parent, PID =". $pid. " \ n ";
} else {
echo "I am the child, PID =". $pid. " \ n ";
}
echo "This is a echo after I called the fork command\n";
?>
