Php 停止在空格上拆分正则表达式

我正在编写一个解析器，试图自动化一种方法，可以将任何参数作为参数传递，如下所示：

$content = '{loop for=products showPagination="true" paginationPosition="both" wrapLoop="true" returnDefaultNoResults="true" noResultsHeading="Nothing Found" noResultsHeadingSize="2" noResultsParagraph="We have not found any products in this category, please try another."}{/loop}';
preg_match_all('/([a-zA-Z]+)=([\/\.\"a-zA-Z0-9&;,_-]+)/', str_replace('"', '"', $content), $attr);

if (!is_array($attr)) return array();

for ($z = 0; $z < count($attr[1]); $z++) if (isset($attr['1'][$z])) $attrs[$attr['1'][$z]] = trim($attr['2'][$z], '"');

echo json_encode($attrs);

---

您会注意到最后两个参数都在第一个单词后停止。

我建议您更改

preg\u match\u all

函数，如下所示

preg_match_all('/([a-zA-Z]+)=("[^"]*"|\S+)/', str_replace('"', '"', $content), $attr);

它将首先贪婪地匹配所有双引号内容。如果没有任何双引号块，则它将匹配一个或多个非空格字符

输出：

{"for":"products","showPagination":"true","paginationPosition":"both","wrapLoop":"true","returnDefaultNoResults":"true","noResultsHeading":"Nothing Found","noResultsHeadingSize":"2","noResultsParagraph":"We have not found any products in this category, please try another."}

{"for":"products","showPagination":"true","paginationPosition":"both","wrapLoop":"true","returnDefaultNoResults":"true","noResultsHeading":"Nothing Found","noResultsHeadingSize":"2","noResultsParagraph":"We have not found any products in this category, please try another."}
