有时候需要转换html格式的字符串为文本,但又需要保持一定的格式,比如要求段落变成的分段格式就可以用下面这个函数
function
html2text(
$str
){
$str
= preg_replace(
"/<style .*?<\\/style>/is"
,
""
,
$str
);
$str
= preg_replace(
"/<script .*?<\\/script>/is"
,
""
,
$str
);
$str
= preg_replace(
"/<br \\s*\\/>/i"
,
">>>>"
,
$str
);
$str
= preg_replace(
"/<\\/?p>/i"
,
">>>>"
,
$str
);
$str
= preg_replace(
"/<\\/?td>/i"
,
""
,
$str
);
$str
= preg_replace(
"/<\\/?div>/i"
,
">>>>"
,
$str
);
$str
= preg_replace(
"/<\\/?blockquote>/i"
,
""
,
$str
);
$str
= preg_replace(
"/<\\/?li>/i"
,
">>>>"
,
$str
);
$str
= preg_replace(
"/ /i"
,
" "
,
$str
);
$str
= preg_replace(
"/ /i"
,
" "
,
$str
);
$str
= preg_replace(
"/&/i"
,
"&"
,
$str
);
$str
= preg_replace(
"/&/i"
,
"&"
,
$str
);
$str
= preg_replace(
"/</i"
,
"<"
,
$str
);
$str
= preg_replace(
"/</i"
,
"<"
,
$str
);
$str
= preg_replace(
"/“/i"
,
‘"‘
,
$str
);
$str
= preg_replace(
"/&ldquo/i"
,
‘"‘
,
$str
);
$str
= preg_replace(

,

,
$str

$str

$str

,
$str

$str

,

,
$str
);
$str
= preg_replace(
"/&rdquo/i"
,
‘"‘
,
$str
);
$str
=
strip_tags
(
$str
);
$str
= html_entity_decode(
$str
, ENT_QUOTES,
"utf-8"
);
$str
= preg_replace(
"/&#.*?;/i"
,
""

);
return
