Question

我正在试图弄清楚如何将rand()函数的结果保存到10个不同的文件中。

这是我的代码：

<?php 
for($i = 0; $i < 10; $i++)
{
    $rand_valuec = rand(0,16); 
    echo "<b>Your Lucky Number is</b>: " . $rand_valuec . " <br />";
    $fp = fopen("results.php", "w");
    fwrite($fp, $rand_valuec); 
    fclose($fp);
}

示例输出：

Your Lucky Number is: 6 
Your Lucky Number is: 16 
Your Lucky Number is: 16 
Your Lucky Number is: 8 
Your Lucky Number is: 6 
Your Lucky Number is: 10 
Your Lucky Number is: 13 
Your Lucky Number is: 5 
Your Lucky Number is: 6 
Your Lucky Number is: 5

results.php 包含：

我需要将每个结果保存到一个新文件中;例如1result.php，2result.php，3result.php，4result.php，...，10result.php。有任何想法吗？ :-)谢谢！

Answer 1

您可以将文件更改为：

$fp = fopen($i."result.php", "w");

Answer 2

<?php 
for($i=0; $i < 10; $i++)
{
$rand_valuec = rand(0,16); 
echo "<b>Your Lucky Number is</b>: ".$rand_valuec." <br />";
$fp = fopen($i."results.php", "w");
fwrite($fp, $rand_valuec); 
fclose($fp);
}
?>

Answer 3

试一试：

<?php 

$numberOfFiles = 10;
$numberOfLinesPerFile = 10;

$path = "/home/your-user/your-path/";

for ($fileIndex = 1; $fileIndex <= $numberOfFiles; $fileIndex++) {

    $contentFile = "";

    for ($i = 0; $i < $numberOfLinesPerFile; $i++) { 

        $rand_valuec = rand(0,16); 
        $content = "<b>Your Lucky Number is</b>: ".$rand_valuec." <br />";
    }

    file_put_contents($path . $fileIndex . "result.php", $content);
}

将结果从rand（）保存到新文件？
