Question

我从这个论坛获得此代码，问题是我无法获得所需的输出，首先我检查过如果前缀与我想要显示的电话号码相匹配，否则我要存储到file3.csv的所有结果。问题是，当我发出else语句时，我会得到匹配前缀的数字。有任何建议请。

$file1 ="csv/file1.csv";
$file2 ="csv/file2.csv";

// Get an array of each line of the first file.
$prefix_contry = explode("\n", file_get_contents($file1));

$fileo=fopen("csv/file3.csv","w");

foreach($prefix_contry as $prefix_line) {

// Extract numbers from begging of each line.
if(preg_match('/^([0-9]+)/', $prefix_line, $prefix_matches)) {
  if($file = fopen($file2, "r")) {

    // Loop through second file line by line...
     while(($line = fgets($file)) !== false) {
        $line = rtrim($line);

        // Pull out number from second file.
       if(preg_match('/([0-9]+)/', $line, $matches)) {

         // Check to see if number begins with prefix
         if(preg_match("/^{$prefix_matches[1]}/", $matches[1])) {

           echo $line."&nbsp;".$prefix_matches[1];
          }
           else{
             fputcsv($fileo,array($line),",",'"');

              }
            }
        }
        fclose($file);
    } 
     else {  
      echo  "Couldn't open file.";  
    }
  }
}

2个csv文件的结构：

file1.csv                            file2.csv
Prefix      Country             Phone Number     Country    Names
