如果在php中的字符串之间找到两个空格，如何删除一个空格？
问题描述：
I want to remove one white space if found two white space between phrase in php, I can detect if there is two white space or not, but I can not remove white space, here is how I tried,
my_doublespace = "Marketing and Sales Staff";
if(strpos($my_doublespace, ' ') > 0){
dd('including double space');
}
else{
dd('no double');
}I want the result like this "Marketing and Sales Staff", only one white space between "Marketing" and "and". Is there anyway to remove it?
答
I would do this
$str = preg_replace('/\s{2,}/', ' ', $str);
This will change 2 or more spaces to a single space.
Because, do you want 3 spaces becoming 2, which is the result of some of the other answers.
I would toss a trim() in to the mix for good measure.
You can "roll" your own trim like this:
$str = preg_replace(['/\s{2,}/','/^\s+|\s+$/'],[' ',''], $str);
You can try this live here

str_replace function also works fine.
$my_doublespace = str_replace(' ', ' ', $my_doublespace);
