解析一个类似CVS的文件，并将其存储为字典

Question

我有我产生，看起来像这样的文本文件：

ipaddress,host 
ipaddress,host 
ipaddress,host 
ipaddress,host 
ipaddress,host 
... 

我怎么会通过这个文件中读取并存储每个线作为键值对？

ex。

array{ 
     [ipaddress]=>[host] 
     [ipaddress]=>[host] 
     [ipaddress]=>[host] 
     .......... 
    } 

Answer 1

$arr = file('myfile.txt'); 
$ips = array(); 

foreach($arr as $line){ 
    list($ip, $host) = explode(',',$line); 
    $ips[$ip]=$host; 
} 

Answer 2

对于一个简单的解决方案：

<?php 
    $hosts = file('hosts.txt', FILE_SKIP_EMPTY_LINES); 
    $results = array(); 
    foreach ($hosts as $h) { 
     $infos = explode(",", $h); 
     $results[$infos[0]] = $infos[1]; 
    } 
?> 

Answer 3

尝试的功能explode。

//open a file handler 
$file = file("path_to_your_file.txt"); 

//init an array for keys and values 
$keys= array(); 
$values = array(); 

//loop through the file 
foreach($file as $line){ 

    //explode the line into an array 
    $lineArray = explode(",",$line); 

    //save some keys and values for this line 
    $keys[] = $lineArray[0]; 
    $values[] = $lineArray[1]; 
} 

//combine the keys and values 
$answer = array_combine($keys, $values); 

Answer 4

<?php 
$handle = @fopen("ip-hosts.txt", "r"); 
$result = array(); 
if ($handle) { 
    while (($buffer = fgets($handle, 4096)) !== false) { 
     $t = explode(',', $buffer); 
     $result[$t[0]] = $t[1]; 
    } 
    if (!feof($handle)) { 
     echo "Error: unexpected fgets() fail\n"; 
    } 
    fclose($handle); 
} 
// debug: 
echo "<pre>"; 
print_r($result); 
echo "</pre>" 
?>
