我有一个在 ubuntu 中运行完美的脚本，最近我将完全相同的脚本复制到 centos6 服务器 我收到以下错误:
PHP Warning: array_map(): Argument #2 should be an array in /copy_scripts/classes/Vserver.class.php on line 245
代码
/**
* Get an array of open files
* @param array $aExt
* @return array of arrays ['views','size','path']
*/
public function getOpenFiles($aExt=array()) {
$aOpenFiles = self::GetList(self::$sLogOpenFiles);
$aOpenFiles = array_map( create_function('$v', '
$v = trim($v);
$aFile = preg_split("#[\t\s]+#",$v);
$oFile = new VserverFile($aFile[2]);
$oFile->setViews($aFile[0]);
return $oFile;'),
$aOpenFiles
);
//echo "<pre>";
//print_r($aOpenFiles);
return $aOpenFiles;
}
会不会是php版本的区别？
中心:
PHP 5.3.3 (cli) (built: Jul 3 2012 16:53:21)
Ubuntu
PHP 5.3.10-2 (cli) (built: Feb 20 2012 19:39:00)

到目前为止我尝试了什么:
- 更改 php.ini 中的设置并重新启动 php。

最佳答案
由于 array_map 提示 $aOpenFiles 不是数组，您可能需要查看该变量。
public function getOpenFiles($aExt=array()) {
$aOpenFiles = self::GetList(self::$sLogOpenFiles);
if ( !is_array($aOpenFiles) ) {
var_dump($aOpenFiles);
die('not an array');
}
$aOpenFiles = array_map( ...
引用:
static public function GetList($sLogPath) {
if ($sList = self::GetLog($sLogPath)) {
return explode(PHP_EOL,trim($sList));
}
}
... 如果 $sList 的计算结果为 false(这很可能发生，因为 GetLog 在某些情况下返回 false)，此函数返回 nothing.
您必须在某处检查该条件。 在哪里 取决于您希望脚本对什么条件使用react。例如
static public function GetList($sLogPath) {
if ($sList = self::GetLog($sLogPath)) {
return explode(PHP_EOL,trim($sList));
}
return array();
}
会“修复”错误，但是否可行是另一个问题；它可能只会“隐藏”一个症状——而不是潜在的问题。一定要有日志文件吗？ GetList(GetLog()) 必须返回一个(非空)数组吗？等等……
关于PHP:警告:array_map():参数 #2 应该是一个数组，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/13118343/
