我目前有一个包含文件名的数组，我现在想在目录中使用通配符搜索通过该数组foreach并找到匹配的文件。
如何使用glob()函数执行此操作？
您可以简单地提取foreach循环中与通配符搜索匹配的每个文件：
$search = "*.txt";
// if this is what you mean by indexed string variable?
$file = array("updated.txt", "new.txt");
// getcwd() will retrieve the current directory but is not needed - this just shows
// that you can supply a directory if you wanted to.
function MatchFile($file,$search)
{
$temp = array();
$i = 0;
foreach (glob(getcwd().$search) as $filename) :
if (count($file) > $i):
array_push($temp, ($filename == $file[$i++])? $filename : "");
else:
// stops the index overflow error
break;
endif;
endforeach;
return $temp;
}
foreach (MatchFile($file,$search) as $found):
echo $found . " was found!";
endforeach;
这只是opendir();的替代品。
