这是我的代码:
<?php
require_once 'dbconnect.php';
function execInBackground($cmd) {
if (substr(php_uname(), 0, 7) == "Windows"){
pclose(popen("start /B ". $cmd, "r"));
}
else {
exec($cmd . " > /dev/null &");
}
}
if(isset($_GET['date'])){
//CHECK LOCK
$checkLock = "Select IS_FREE_LOCK('overnight') as `lock`;";
$result = mysql_query($checkLock) or die(mysql_error());
while($information = mysql_fetch_array($result)){
if($information['lock'] == 0){
die('Overnight is already running, please try again later.');
}
}
execInBackground("php overnightQueries.php {$_GET['date']}");
//echo "<pre>".print_r($output2, true)."</pre>";
header('Refresh: 3; url=index.php');
die('running queries...');
}
else {
die('PLEASE SET DATE');
}
?>
我正在使用Windows机器。
我收到以下警告:
警告:popen(start / B php overnightQueries.php 2011_08_12,r):第5行的C:\ inetpub \ GTSA \ runOvernight.php没有错误
和
警告:pclose()期望参数1为资源,第5行的C:\ inetpub \ GTSA \ runOvernight.php中给出布尔值
答案 0 :(得分:0)
$handle = popen("start /B ". $cmd, "r");
if ($handle === FALSE) {
die("Unable to execute $cmd");
}
pclose($handle);
如果出现问题,popen会返回false,你会盲目地传递给pclose,因此会出现第二个错误。
至于第一个错误,请检查PHP是否在您的环境路径中 - 您可能需要指定php.exe的绝对路径。
