当没有想法时,你应该转向stackoverflow。 这就是我正在做的:)我需要用 90,000 个随机文件填充一个目录(不需要内容),但由于某种原因,我的无限循环脚本只创建大约 10 个文件(从 1-10 个),仅此而已。我做错了什么?
<?
$counter = 1;
while ($counter < 90000) {
$rand = rand(1, 9999999999999999999999);
print (" counter = " . $counter . "<BR>");
$ourFileName = "$rand";
$ourFileHandle = fopen($ourFileName, 'w') or die("can't open file");
fclose($ourFileHandle);
$counter++;
}
?>
原因
如下:
php > $x = 9999999999999999999999;
php > echo $x;
1.0E+22
php > echo rand(1, 9999999999999999999999);
1
php > echo rand(1, 9999999999999999999999);
1
php > echo rand(1, 9999999999999999999999);
1
php > echo rand(1, $x);
1
$NoOfFiles = 10;
for($i = 0; $i < $NoOfFiles; $i++){
$FileHandler = fopen($i.".txt", 'w') or die("can't open file");
fclose($FileHandler);
echo "File '". $i.".txt' has been created<br/>";
}
只需将 $NoOfFiles 变量更改为您想要创建的文件数量即可...
