This article mainly introduces the method of PHP regular deletion of width and height styles in HTML code, involving PHP regular matching, replacement and other operation skills for HTML code. Friends who need it can refer to it
Due to work needs , need to collect html and save the html content into the database. In order to avoid affecting usage, the width and height styles need to be deleted. For example, width, height, etc. in pictures and p.
However, in the collected HTML, the styles are written differently, such as upper and lower case, spaces in the middle, etc.
So I wrote the following method using PHP regular to filter these weird styles.
The code is as follows:
Demonstration:
![]()
HTML; echo '
![]()
'; echo '原内容:'.PHP_EOL; echo $html.PHP_EOL.PHP_EOL; echo '过滤后内容:'.PHP_EOL; echo clear_wh($html); echo ' '; ?>
Output :
原内容:
![]()
过滤后内容:
![]()
![]()
![]()
