I have a sentence like this.
1 2 3 4
As you see, in between 1 2 and 3 text, there are extra spaces. I want the output with only one space between them. So my output should be
1 2 3 4
How can I use a PHP function to get the desired output?
$str = "1 $nbsp; 2 3 4";
$new_str = str_replace(" ", '', $str);
A little late to answer but hopefully might help someone else. The most important while extracting content from html is to use utf8_decode() in php (Community warning: "This function is DEPRECATED as of PHP 8.2.0. Relying on this function is highly discouraged" - from PHP manual). Then all other string operations become a breeze. Even foreign characters can be replaced by directly copy pasting characters from browser into the php code. The following function replaces with a space. Then all extra white spaces are replaced with a single white space using preg_replace(). Leading and trailing white spaces are removed in the end.
function clean($str)
{
$str = utf8_decode($str);
$str = str_replace(" ", " ", $str);
$str = preg_replace('/\s+/', ' ',$str);
$str = trim($str);
return $str;
}
$html = "1 $nbsp; 2 3 4";
$output = clean($html);
echo $output;
1 2 3 4
if your string actually has " ",
$str="1 2 3 4";
$s = str_replace(" ","",$str);
print $s;
echo str_replace ( " ", "", "1 2 3 4" );
just remember you need to echo out the result of the str_replace and you alo dont need to worry about white spaces a the browser will only show one white space.
This did the job for me:
preg_replace('~\x{00a0}~siu',' ',$content);
s and i pattern modifiers seem totally pointless to me.
