逐行读取php中的CSV并存储在变量中

Question

我想在php中读取一个CSV文件，就像

203.88.0.0,203.88.31.255  
84.64.0.0,84.71.255.255  
123.63.128.0,123.63.255.255  
112.79.0.0,112.79.255.255  
1.38.0.0,1.39.255.255  
114.31.128.0,114.31.191.255  

并在如下变量中获取输出：

MAX_checkClient_Ip('10.52.81.60|10.52.81.61', '=^')
or MAX_checkClient_Ip('10.66.40.136|10.66.40.137', '=^')
or MAX_checkClient_Ip('10.99.53.15|10.99.53.21', '=^')
or MAX_checkClient_Ip('10.99.53.143|10.99.53.149', '=^')
or MAX_checkClient_Ip('31.173.64.0|31.173.71.255', '=^')
or MAX_checkClient_Ip('31.173.192.0|31.173.193.255', '=^')
or MAX_checkClient_Ip('31.173.240.0|31.173.243.255', '=^')
or MAX_checkClient_Ip('37.28.160.0|37.28.191.255', '=^')
or MAX_checkClient_Ip('37.29.0.0|37.29.15.255', '=^')

注意第一行没有“或”

---

public function create_channel()
{
                $file_handle = fopen("IP_SCRIPT.csv", "r");

while (!feof($file_handle) ) {

$line_of_text = fgetcsv($file_handle, 1024);

//print "or MAX_checkClient_Ip('".$line_of_text[0] ."|". $line_of_text[1]."', '=^')\r\n";
$str[]="or MAX_checkClient_Ip('".$line_of_text[0] ."|". $line_of_text[1]."', '=^')\r\n";

}
for($i=0;$i<count($str);$i++)
{
        echo $str[$i];
}


fclose($file_handle);

}

但我得到的输出为

or MAX_checkClient_Ip('203.88.0.0|203.88.31.255', '=^')
or MAX_checkClient_Ip('84.64.0.0|84.71.255.255', '=^')
or MAX_checkClient_Ip('123.63.128.0|123.63.255.255', '=^')
or MAX_checkClient_Ip('112.79.0.0|112.79.255.255', '=^')
or MAX_checkClient_Ip('1.38.0.0|1.39.255.255', '=^')
or MAX_checkClient_Ip('114.31.128.0|114.31.191.255', '=^')
or MAX_checkClient_Ip('|', '=^')

我不想在第一行使用“或”，也不需要最后一行

稍微调整您的代码，将“或”的处理移出读取循环并进入打印循环：

public function create_channel()
{
     $file_handle = fopen("IP_SCRIPT.csv", "r");
     while (!feof($file_handle))
     {
         $line_of_text = fgetcsv($file_handle, 1024);
         $str[]="MAX_checkClient_Ip('".$line_of_text[0] ."|". $line_of_text[1]."', '=^')";
     }
     fclose($file_handle);
     for($i=0; $i<count($str); $i++)
     {
         if ($i > 0) {
              print "or ";
         }
         print $str[$i] . "\n";
     }
}

@Aziz Saleh 的建议很好。整个for 循环可以替换为：

print implode("\nor ", $str) . "\n";
