删除特定符号前后的字符

Question

I have a string <?php $linktitle = get_the_title();?> that stores the title of the post. The string has a title like this:

If Your Wi-Fi Is Terrible, Check Your Router – The New York Times

How can I remove everything before and including the –? I'm using: <?php echo strstr($linktitle, '&#8211;'); ?> and it outputs:

– The New York Times

Answer 1

Try using preg_replace:

preg_replace("/.+?( –)/", '', $linktitle)

If you want to remove the whitespace after the - too:

preg_replace("/.+?( –)\s*/", '', $linktitle)

This uses regular expression to match a pattern defined by any character except newline 1 or more times (.+), until it meets (?) a space followed by a dash (( –)), then a whitespace (\s) 0 or more times (*). Preg_replace then replaces the matched pattern with an empty string.
