我有以下字符串：
Host dnsmgr Username Refresh State Reg.Time
sip.voicetrading.com:5060 N travelAsk 105 Registered Thu, 27 Nov 2014 15:57:43
sip.alonia.es:5060 N user431 225 Registered Thu, 27 Nov 2014 23:28:24
我想以某种方式将此字符串作为关联数组。
这样的事情：
array(
'sip.voicetrading.com' => array (
'port' => 5060,
'username' =>'travelAsk',
'refresh' => 105,
'state' => 'Registered',
'time' => 'Thu, 27 Nov 2014 15:57:43'
),
'sip.alonia.es' => array (
'port' => 5060,
'username' =>' user431',
'refresh' => 225,
'state' => 'Registered',
'time' => 'Thu, 27 Nov 2014 23:28:24'
)
);
你能告诉我一个最好的方法吗？
到目前为止，我尝试过这样的事情：
$peer = array(
"data"=>
"Host dnsmgr Username Refresh State Reg.Time
sip.voicetrading.com:5060 N travelIhome 105 Registered Thu, 27 Nov 2014 16:39:45 " ;
foreach (explode("\n", $peer['data']) as $line) {
$a = strpos('z' . $line, ':') - 1;
if ($a >= 0) {
$arrTrunkSettings = explode (' ', trim(substr($line, $a + 1)));
foreach ($arrTrunkSettings as $key => $value) {
if (!empty($value)) {
$data[trim(substr($line, 0, $a))][] = $value;
}
}
}
}
并且Output就像这个带有数字索引的数组： 但这实际上并不是我所需要的。
array (
"sip.voicetrading.com" =>
array(
[0]=> "5060"
[1]=> "N"
[2]=> "travelAsk"
[3]=> "105"
[4]=> "Registered"
[5]=> "Thu,"
[6]=> "27"
[7]=> "Nov"
[8]=> "2014"
[9]=> "16:32:45"
)
)

编辑：相当短的解决方案。这与我的第一个答案相同，但现在只有一半的代码。首先它获取所有行，然后将标题拉入并将其拆分为单独的数组。然后它可以循环其余的行，并使用标题作为键将它们添加到结果中。
$result = array();
$lines = explode("\n", $string);
$headers = preg_split("/\s+/", array_shift($lines), 6);
foreach ($lines as $line) {
$part = preg_split('/\s+/', $line, 6);
$info = explode(":", $part[0]);
$result[$info[0]]['port'] = $info[1];
for($i = 1; $i < count($headers); $i++) {
$result[$info[0]][$headers[$i]] = $part[$i];
}
}
这会为您提供与您要求的匹配的结果数组。它从标题中获取键/值对，因此如果输入发生更改，则生成的数组也会发生变化，与硬编码解决方案不同。

这是实施：
<?php
$input = "Host dnsmgr Username Refresh State Reg.Time
sip.voicetrading.com:5060 N travelAsk 105 Registered Thu, 27 Nov 2014 15:57:43
sip.alonia.es:5060 N user431 225 Registered Thu, 27 Nov 2014 23:28:24";
$rows = explode("\n", $input);
unset($rows[0]);
$objects = array();
foreach ($rows as $row)
{
$object = array();
echo $row . "\n";
$row = preg_replace("/\\ +/", " ", $row); //Reducing all whitespace into single spaces
$index = strpos($row, " ");
$addr = substr($row, 0, $index);
$host = substr($addr, 0, strpos($addr, ":"));
$port = str_replace($host.":", "", $addr);
$row = substr($row, $index + 1, strlen($row));
$index = strpos($row, " ");
$mgr = substr($row, 0, $index);
$row = substr($row, $index + 1, strlen($row));
$index = strpos($row, " ");
$user = substr($row, 0, $index);
$row = substr($row, $index + 1, strlen($row));
$index = strpos($row, " ");
$refresh = substr($row, 0, $index);
$row = substr($row, $index + 1, strlen($row));
$index = strpos($row, " ");
$state = substr($row, 0, $index);
$row = substr($row, $index + 1, strlen($row));
$object["port"] = $port;
$object["dnsmgr"] = $mgr;
$object["username"] = $user;
$object["refresh"] = $refresh;
$object["state"] = $state;
$object["time"] = $row;
$objects[$host] = $object;
}
print_r($objects);
?>

只使用preg_split()：
<?php
$peer = array( "data" =>
"Host dnsmgr Username Refresh State Reg.Time
sip.voicetrading.com:5060 N travelAsk 105 Registered Thu, 27 Nov 2014 15:57:43
sip.alonia.es:5060 N user431 225 Registered Thu, 27 Nov 2014 23:28:24"
);
$obj = array();
foreach( explode( "\n", $peer['data'] ) as $line ) {
$v1 = preg_split( "/:/", trim( $line ), 2 );
if( sizeof( $v1 ) == 2 ) {
$v2 = preg_split( "/\s+/", $v1[1], 6 );
$obj[$v1[0]] = array(
"port" => $v2[0],
"username" => $v2[2],
"refresh" => $v2[3],
"state" => $v2[4],
"time" => $v2[5]
);
}
}
print_r( $obj );
?>
结果：
Array
(
[sip.voicetrading.com] => Array
(
[port] => 5060
[username] => travelAsk
[refresh] => 105
[state] => Registered
[time] => Thu, 27 Nov 2014 15:57:43
)
[sip.alonia.es] => Array
(
[port] => 5060
[username] => user431
[refresh] => 225
[state] => Registered
[time] => Thu, 27 Nov 2014 23:28:24

设定：
<?php
$peer = array('data' =>
'Host dnsmgr Username Refresh State Reg.Time
sip.voicetrading.com:5060 N travelAsk 105 Registered Thu, 27 Nov 2014 15:57:43
sip.alonia.es:5060 N user431 225 Registered Thu, 27 Nov 2014 23:28:24'
);
首先，将原始数据拆分为行。从第一行中提取字段标签，然后删除此行。将第一个标签替换为"Port"。
$lines = explode ("\n", $peer['data']);
if (count ($lines)) {
$line = array_shift ($lines);
$labels = preg_split ('/\\s+/', trim($line));
$labels[0] = 'Port';
$max_fields = count ($labels);
}
现在循环其余的行。将行拆分为字段，并从第一个字段中提取主机和端口。用端口替换第一个字段。然后使用array_combine()合并标签和数据。
请注意使用$max_fields来避免将Reg.Time拆分为多个字段。仅当Reg.Time是行中的最后一个字段时才有效。
$data = array();
foreach ($lines as $line) {
$fields = preg_split ('/\\s+/', trim($line), $max_fields);
if (count ($fields) < $max_fields) {
// Error
}
$hostport = explode (':', $fields[0], 2);
$host = $hostport[0];
$port = $hostport[1];
$fields[0] = $port;
$data[$host] = array_combine ($labels, $fields);
}
print_r ($data);

有很多方法可以解析这些数据。我觉得最简单的方法就是为它写一个正则表达式。
$peerData = 'Host dnsmgr Username Refresh State Reg.Time
sip.voicetrading.com:5060 N travelAsk 105 Registered Thu, 27 Nov 2014 15:57:43
sip.alonia.es:5060 N user431 225 Registered Thu, 27 Nov 2014 23:28:24';
// Split the string into lines
$lines = explode("\n", $peerData);
// Remove the header
unset($lines[0]);
// Loop over each line
$peers = [];
foreach ($lines as $line) {
$matches = [];
preg_match('/\s*(?P<hostname>[\w\.]+):(?P<port>\d+)\s*(?P<dnsmgr>.)\s*(?P<username>\w+)\s*(?P<refresh>\d+)\s*(?P<state>\w+)\s*(?P<time>.+)/', $line, $matches);
// Build the entry
$peers[$matches['hostname']] = [
'port' => $matches['port'],
'username' => $matches['username'],
'refresh' => $matches['refresh'],
'state' => $matches['state'],
'time' => $matches['time'],
];
}
print_r($peers);
