PHP 多进程实践（三）
编写脚本 test1.php
<?php date_default_timezone_set( 'Asia/Chongqing');
$tasks = array(
'http://localhost/feedbowl/t2.php?job=task1',
'http://localhost/feedbowl/t2.php?job=task2',
'http://localhost/feedbowl/t2.php?job=task3'
);
$mh = curl_multi_init();
foreach ($tasks as $i => $task){
$ch[$i] = curl_init();
curl_setopt($ch[$i], CURLOPT_URL, $task);
curl_setopt($ch[$i], CURLOPT_RETURNTRANSFER, 1);
curl_multi_add_handle($mh, $ch[$i]);
}
do {$mrc = curl_multi_exec($mh,$active); } while ($mrc == CURLM_CALL_MULTI_PERFORM);
while ($active && $mrc == CURLM_OK) {
if (curl_multi_select($mh) != -1) {
do {$mrc = curl_multi_exec($mh, $active); } while ($mrc == CURLM_CALL_MULTI_PERFORM);
}
}
// completed, checkout result
foreach ($tasks as $j => $task){
if (curl_error($ch[$j])){
echo "task ${j} [$task ] error " , curl_error($ch[$j]), "\r\n" ;
} else {
echo "task ${j} [$task ] get: \r\n" , curl_multi_getcontent($ch[$j]), "\r\n" ;
}
}
?>编写脚本 test2.php
<?php date_default_timezone_set( 'Asia/Chongqing');
echo "child start, pid ", getmypid(), "\r\n" ;
for ($i=0; $i<5; ++$i){
beep();
}
exit (0);
// ***
function beep(){
echo getmypid(), "\t" , date('Y-m-d H:i:s' , time()), "\r\n";
sleep(1);
}
?>
