正則運算式Fortinet日志PHP-有解無憂

我正在嘗試在 PHP 中決議日志 fortinet。我從 Fortinet 的食譜中獲取了一個日志示例。

這是我的正則運算式代碼。我想創建一個陣列，它的值型別為索引，而不是他的值。例如：[日期]=>2019-05-10 [時間]=>11:50:48 ... [srcip]=>172.16.200.254

$regex = '/[a-zA-Z] =[0-9]{4}-[0-9]{2}-[0-9]{2} [a-zA-Z] =[0-9]{2}:[0-9]{2}:[0-9]{2}(\\.[0-9]{1,3})? [a-zA-Z] ="[^"]*" [a-zA-Z] ="[a-zA-Z] " [a-zA-Z] ="[^"]*" [a-zA-Z] ="[^"]*" [a-zA-Z] ="[^"]*" [a-zA-Z] =[0-9]  [a-zA-Z] =\\b(?:(?:2(?:[0-4][0-9]|5[0-5])|[0-1]?[0-9]?[0-9])\\.){3}(?:(?:2([0-4][0-9]|5[0-5])|[0-1]?[0-9]?[0-9]))\\b [a-zA-Z] =[0-9]  [a-zA-Z] ="[^"]*" [a-zA-Z] ="[^"]*" [a-zA-Z] =\\b(?:(?:2(?:[0-4][0-9]|5[0-5])|[0-1]?[0-9]?[0-9])\\.){3}(?:(?:2([0-4][0-9]|5[0-5])|[0-1]?[0-9]?[0-9]))\\b [a-zA-Z] =[0-9]  [a-zA-Z] ="[^"]*" [a-zA-Z] ="[^"]*" [a-zA-Z] =[0-9]  [a-zA-Z] =[0-9]  [a-zA-Z] ="[^"]*" [a-zA-Z] =[0-9]  [a-zA-Z] ="[^"]*" [a-zA-Z] ="[^"]*" [a-zA-Z] ="[^"]*" [a-zA-Z] ="[^"]*" [a-zA-Z] ="[^"]*" [a-zA-Z] ="[^"]*" [a-zA-Z] =[0-9]  [a-zA-Z] =[0-9]  [a-zA-Z] =[0-9]  [a-zA-Z] =[0-9]  [a-zA-Z] =[0-9]  [a-zA-Z] ="[^"]*"/i';

$str = 'date=2019-05-10 time=11:50:48 logid="0001000014" type="traffic" subtype="local" level="notice" vd="vdom1" eventtime=1557514248379911176 srcip=172.16.200.254 srcport=62024 srcintf="port11" srcintfrole="undefined" dstip=172.16.200.2 dstport=443 dstintf="vdom1" dstintfrole="undefined" sessionid=107478 proto=6 action="server-rst" policyid=0 policytype="local-in-policy" service="HTTPS" dstcountry="Reserved" srccountry="Reserved" trandisp="noop" app="Web Management(HTTPS)" duration=5 sentbyte=1247 rcvdbyte=1719 sentpkt=5 rcvdpkt=6 appcat="unscanned"';

preg_match_all($regex, $str, $matches, PREG_SET_ORDER, 0);

var_dump($matches);

也許使用帶有分支重置組的小模式就足夠了，其中組 1 包含鍵，組 2 包含值：

([^\s=] )=(?|"([^"]*)"|(\S ))

正則運算式演示

例子

$regex = '/([^\s=] )=(?|"([^"]*)"|(\S ))/';

$str = 'date=2019-05-10 time=11:50:48 logid="0001000014" type="traffic" subtype="local" level="notice" vd="vdom1" eventtime=1557514248379911176 srcip=172.16.200.254 srcport=62024 srcintf="port11" srcintfrole="undefined" dstip=172.16.200.2 dstport=443 dstintf="vdom1" dstintfrole="undefined" sessionid=107478 proto=6 action="server-rst" policyid=0 policytype="local-in-policy" service="HTTPS" dstcountry="Reserved" srccountry="Reserved" trandisp="noop" app="Web Management(HTTPS)" duration=5 sentbyte=1247 rcvdbyte=1719 sentpkt=5 rcvdpkt=6 appcat="unscanned"';

preg_match_all($regex, $str, $matches, PREG_SET_ORDER, 0);

$result = array_reduce($matches, function($carry, $item) {
    $carry[$item[1]] = $item[2];
    return $carry;
}, []);

print_r($result);

輸出

這聽起來很荒謬，但您的日志就像 HTML 屬性，創建一個 html 并決議屬性作業正常。
