|affffc100|Hitem:bb:101:1:1:1:1:48:-30:47:18:5:2:6:6:0:0:0:0:0:0:0:0|h[Subject Name]|h|r
my usual printed out variable is ^ 我通常打印出来的变量是^
|cffffc700|Hitem:x:x:x:x:x:x:x:x:x:x:x:x:x:x:x:x:x:x:x:x:x:x|h[SUBJECT_NAME]|h|r
my pattern is ^ 我的模式是^
ALL X's can be aZ, 0-9 所有X可以是aZ,0-9
in one column I have many variables like that (up to 8). 一栏中我有很多类似的变量(最多8个)。 and all variables are mixed with strings like that:
并且所有变量都与这样的字符串混合:
|affffc100|Hitem:bb:101:1:1:1:1:48:-30:47:18:5:2:6:6:0:0:0:0:0:0:0:0|h[Gold]|h|r NEW SOLD |affffc451|Hitem:bb:101:1:1:1:1:25:-33:12:42:5a:2f:6w:6:0:0:0:0f:0:0a:0b:0|h[Copper]|h|r maximum price 15k|affffx312|Hitem:bb:101:1:1:1:1:25:-33:12:42:5a:2f:6w:6:0:0:0:0f:0:0a:0b:0|h[Silver]|h|r
In one variable I want to clean all these unnecessary patterns and leave only subject name in brackets. 在一个变量中,我想清除所有这些不必要的模式,并仅在括号内保留主题名称。 []
[]
So; 所以;
|cffffc700|Hitem:x:x:x:x:x:x:x:x:x:x:x:x:x:x:x:x:x:x:x:x:x:x|h[SUBJECT NAME]|h|r
needs to leave only SUBJECT_NAME in my variable. 只需要在变量中保留SUBJECT_NAME。 just to remind, I have always more than one from these pattern in my every variable... (up to 8) I've searched it everywhere but couldn't find any reasonable answers NOR good patterns.
提醒一下,在每个变量中,我总是从这些模式中获取不止一个...(最多8个)我已经在所有位置进行了搜索,但找不到任何合理的答案,也没有好的模式。 Tried to make it myself but I guess I need to take all these patterns and make it array and clean it and only leave these subject names but I don't know exactly how to do it.
试图自己制作,但我想我需要采用所有这些模式,并将其排列并清理,仅保留这些主题名称,但我不知道该怎么做。
how do I convert this to : 我如何将其转换为:
|affffc100|Hitem:bb:101:1:1:1:1:48:-30:47:18:5:2:6:6:0:0:0:0:0:0:0:0|h[Gold]|h|r NEW SOLD |affffc451|Hitem:bb:101:1:1:1:1:25:-33:12:42:5a:2f:6w:6:0:0:0:0f:0:0a:0b:0|h[Copper]|h|r maximum price 15k|affffx312|Hitem:bb:101:1:1:1:1:25:-33:12:42:5a:2f:6w:6:0:0:0:0f:0:0a:0b:0|h[Silver]|h|r
this: 这个:
Gold NEW SOLD Copper maxiumum price 15k Silver
what should I use, preg_replace? 我应该使用preg_replace吗?
one more thing left, when I have a string without my special pattern, I get empty result from the function eg: 还有一件事,当我有一个没有特殊模式的字符串时,我从函数中得到空结果,例如:
$str = "15KKK sold, 20KK updated";
expected result: 预期结果:
"15KKK sold, 20KK updated" // same without any pattern
but ^ that one returns EMPTY result.. 但是^返回空结果。
another string: 另一个字符串:
$str = "|affffc100|Hitem:bb:101:1:1:1:1:48:-30:47:18:5:2:6:6:0:0:0:0:0:0:0:0|h[Uranium]|h|r 155kk |affffc451|Hitem:bb:101:1:1:1:1:25:-33:12:42:5a:2f:6w:6:0:0:0:0f:0:0a:0b:0|h[Metal]|h|r is sold";
expected result: 预期结果:
"Uranium 155kk Metal is sold"
if I use that function with non-pattern string it returns empty result that's my problem now 如果我将该函数与非模式字符串一起使用,它将返回空结果,这就是我现在的问题
thank you very much 非常感谢你
try this regex: 试试这个正则表达式:
\|\w{9}\|Hitem(?::-?\w+)+\|h\[(?<SUBJECTNAME>\w+)\]\|h\|r
it will capture each variable sequence, as well as the relevant element name in the named group. 它将捕获每个变量序列以及命名组中的相关元素名称。
I'd do: 我会做:
$str = '|affffc100|Hitem:bb:101:1:1:1:1:48:-30:47:18:5:2:6:6:0:0:0:0:0:0:0:0|h[Gold]|h|r NEW SOLD |affffc451|Hitem:bb:101:1:1:1:1:25:-33:12:42:5a:2f:6w:6:0:0:0:0f:0:0a:0b:0|h[Copper]|h|r maximum price 15k|affffx312|Hitem:bb:101:1:1:1:1:25:-33:12:42:5a:2f:6w:6:0:0:0:0f:0:0a:0b:0|h[Silver]|h|r';
preg_match_all('/h(\[.+?\])\|h\|r([^|]*)/', $str, $m);
for($i=0; $i<count($m[0]); $i++) {
$res .= $m[1][$i] . ' ' . $m[2][$i] . ' ';
}
echo $res,"\n";
Output: 输出:
[Gold] NEW SOLD [Copper] maximum price 15k [Silver]
If you want to keep the strings that don't match, test the result of preg_match: 如果要保留不匹配的字符串,请测试preg_match的结果:
if (preg_match_all('/h(\[.+?\])\|h\|r([^|]*)/', $str, $m)) {
for($i=0; $i<count($m[0]); $i++) {
$res .= $m[1][$i] . ' ' . $m[2][$i] . ' ';
}
} else {
$res = $str;
}
echo $res,"\n";
