从字符串中移除加号（+）[复制]

Question

This question already has an answer here:

• How can I check for a plus sign using regular expressions? 2 answers

I am trying to use preg_replace() to remove a plus sign (+) from my string. I used

$variation = preg_replace('/[^\p{L}\p{N}\s]/u', '', $variation);

But that removed periods (.) too, which I need it in the string. Is there a way to just remove the plus sign?

Answer 1

Although the original answer to this question does achieve the intended effect, it is not the most efficient way to do this simple task. As noted in the comments above, the use of str_replace() is preferred in this case.

$variation = str_replace("+", "", $variation);

ORIGINAL ANSWER:

This works to remove only a plus sign:

$variation = preg_replace(/[+]/, "", $variation);

You can see it work here: http://www.phpliveregex.com/p/1Fb (be sure you select the preg_replace function)
