[英]PHP, In a string, how to put two words beside each other or more in parentheses?
在一個字符串中,如何在括號中將兩個或多個大寫字母彼此相鄰的單詞放在一起。 例:
$string = "My name is John Ed, from Canada";
輸出如下:( (My) name is (John Ed), from (Canada)
第一個想法可能如下所示:
<?php
$str = "My name is John Ed, from Canada";
echo preg_replace("/([A-Z]\\w*)/", "($1)", $str); //(My) name is (John) (Ed), from (Canada)
?>
(約翰艾德)的事情應該有點棘手......
那這個呢:
<?php
$str = "My name is John Ed, from Canada and I Do Have Cookies.";
echo preg_replace("/([A-Z]{1}\w*(\s+[A-Z]{1}\w*)*)/", "($1)", $str); //(My) name is (John Ed), from (Canada) and (I Do Have Cookies).
?>
<?php
$str = "My name is John Ed, from Canada";
echo preg_replace('/([A-Z]\w*(\s+[A-Z]\w*)*)/', "($1)", $str);
?>
如果要與unicode兼容,請使用以下命令:
$str = 'My name is John Ed, from Canada, Quebec, Saint-Laurent. My friend is Françoise';
echo preg_replace('/(\p{Lu}\pL*(?:[\s,-]+\p{Lu}\pL*)*)/', "($1)", $str);
輸出:
(My) name is (John Ed), from (Canada, Quebec, Saint-Laurent). (My) friend is (Françoise)
說明:
( : start capture group 1
\p{Lu} : one letter uppercase
\pL* : 0 or more letters
(?: : start non capture group
[\s,-]+ : space, comma or dash one or more times
\p{Lu} : one letter, uppercase
\pL* : 0 or more letters
)* : 0 or more times non capture group
) : end of group 1

$str = "My name is John Ed, from Canada\n";
echo preg_replace("/([A-Z]\\w+( [A-Z]\\w+)*)/", "($1)", $str); //(My) name is (John Ed), from (Canada)
