如何使用PHP将兰德数字保存在不同的TXT文件中 - how to save rand numbers in different txt files with php

how to save rand numbers in different txt files with php

我只需要一些脚本方面的帮助 - 我想将每 100 兰特数保存在

目录下的不同文本文件中 - 所以每次我让循环生成兰特数字每 100 个随机数我想将它们保存在不同的文本文件中，所以这是如何工作的，但我不知道如何将每个 100 兰特号码保存在它不存在的不同文本文件中

<?php  
    function randz()
    {
        $file_path = $_SERVER['DOCUMENT_ROOT'] . "testing/files/";
        $content = NULL;
        $start = 1111111;
        $ofset = 9999999;
        $counter = 1;
        for($i=1; $i <= 500; $i++)
        {
            if( $i == 100 )
             {
                $rand = mt_rand($start, $ofset) * 999999;
                $cut  = substr($rand, 0,7);
                $content .= $i .'-'. $cut."'r'n";
                $file_path =  $_SERVER['DOCUMENT_ROOT'] . "testing/files/"."text_".$counter++."_".$counter++.".txt";
                continue;
             }
        }
        $fp = fopen( $file_path , "wb" );
        fwrite($fp,$content);
        fclose($fp);
    }
    randz();
?>

如果

可以的话，我将首先对您的代码进行一些评论：

<?php  
    function randz()
    {
        $file_path = $_SERVER['DOCUMENT_ROOT'] . "testing/files/";
        $content = NULL; // You are appending strings, 
                         // so in order to avoid a type cast, you'd prefer:
        $content = "";
        $start = 1111111;
        $ofset = 9999999;
        $counter = 1;
        for($i=1; $i <= 500; $i++)
        {
            // Why a loop and then an if with == ?
            // Maybe you wanted to use if( ($i % 100) == 0 ) ?
            if( $i == 100 )
             {
                $rand = mt_rand($start, $ofset) * 999999;
                $cut  = substr($rand, 0,7);
                $content .= $i .'-'. $cut."'r'n";
                $file_path =  $_SERVER['DOCUMENT_ROOT'] . "testing/files/"."text_".$counter++."_".$counter++.".txt";
                // Never pre/post increment twice the same
                // variable in the same line.
                // Does that increment counter in 1, or two?
                continue;
             }
        }
        $fp = fopen( $file_path , "wb" );
        fwrite($fp,$content);
        fclose($fp);
    }
    randz();
?>

为什么不只是，

<?php  
    function randz($file_number)
    {
        $file_path = $_SERVER['DOCUMENT_ROOT'] . "testing/files/";
        $content = array();
        $start = 1111111;
        $ofset = 9999999;
        $counter = 1;
        for($i = 0; i < 100; i++)
        {
            $rand = mt_rand($start, $ofset) * 999999;
            $cut = substr($rand, 0, 7);
            $content[] = $i . "-" . $cut;
        }
        $str_content = implode("'r'n", $content);
        file_put_contents($file_path ."text_" . $filenumber . ".txt", $str_content);
    }
    for($i = 0; $i < 500; $i++)
    {
        randz($i);
    }
?>

我质疑你现有的很多代码。因此，我将回答这个问题：

如何使用PHP将兰德数字保存在不同的TXT文件中

看看file_put_contents().

举个简单的例子：

for ($i = 0; $i < 100; ++$i) {
   file_put_contents("{$i}.txt", rand());
}

尝试：

function randz($fileCount){
  $file_path = $_SERVER['DOCUMENT_ROOT'].'testing/files/text_';
  $content ='';
  for($i=1,$l=$fileCount+1; $i<$l; $i++){
    for($n=1; $n<101; $n++){
      $rand = (string)(mt_rand(1111111, 9999999) * 999999);
      $cut = substr($rand, 0,7);
      $content .= $n.'-'.$cut."'r'n";
    }
    file_put_contents($file_path.$i.'.txt', $content);
  }
}
// create 10 files width 100 random content lines
randz(10);
