This article mainly introduces the solution to the problem of using strip_tags() in PHP to remove html tags that still have blank spaces. It involves related operation skills of PHP regular replacement. Friends in need can refer to it. I hope to be helpful.
The details are as follows:
$subject = strip_tags($newsRs['content']);//去除html标签 $pattern = '/\s/';//去除空白 $content = preg_replace($pattern, '', $subject); $seodata['articledescription'] = mb_substr($content, 0, 80);//截取80个汉字
Note: strip_tags(); in the first step; just replaces the html tags with spaces
For example:
<p> 你好 </p> <p> <br /> </p> <p> alsdkjf;laskjd;flasj; </p> <p> asdjfasjd;lkafsj;lfdkj </p> <p> aksdjfl;ak </p>
After strip_tags() is processed, it becomes
你好 空行... alsdkjf;laskjd;flasj; 空行... asdjfasjd;lkafsj;lfdkj 空行... aksdjfl;ak
This may not be what we want, and then use regular replacement to remove the blanks
The final result:
你好alsdkjf;laskjd;flasj;asdjfasjd;lkafsj;lfdkjaksdjfl;ak
In addition: \s represents a blank character, \S represents a non-blank character (note the case, generally the upper and lower case means the opposite meaning)
