How can I via preg_replace delete spaces between /
For example:
Comercial / Vendedor to Comercial/Vendedor
Compras / Vendas to Compras/Vendas
I want this because users always type the wrong one.
Here is the template I use to delete rows by email. What would be the expression to do what I want above?
function filterEmail($text) {
return preg_replace('/(.*)[a-z0-9\.\_\-]+@[a-z0-9\.\_\-]+\.[a-z]+(.*)/i','', $text);
}
If it's just to eliminate the space between the slashes, use str_replace .
$str = "Comercial / Vendedor";
echo str_replace(" / ", "/", $str);
Output:
Commercial / Salesperson
See the ideone .
The answer from @MarceloDeAndrade is the most appropriate way for the exact case of the problem (and I already received my +1), but just to complement, it follows a version with RegEx taking advantage of its potential: / p>
$str = 'Comercial /Vendedor - Compras/ Vendas - Um / Dois';
$str = preg_replace('(\s*/\s*)','/', $str);
echo $str;
In this case, we are capturing situations where space can vary in quantity, or simply does not exist.
It works if you have more than one space ( a / b );
It works if you do not have space on either side ( a /b or a/ b );
Capture other types of white space (tabs etc).

But as the PHP manual says about str_replace , it is Always remember that:
If you do not need special substitution rules (such as regular expressions), you could always use this function instead of ereg_replace () or preg_replace ().
I recommend using str_replace because of performance. Just for the sake of curiosity, this is what you would do if you were to use preg_replace :
$txt = "Compras / Vendas";
echo preg_replace("# / #g", "", $txt);
Notice that I used # as the regex delimiter, instead of the / that is more usual. This is because / would conflict with our regex, which also looks for a slash in the text. However, if you wanted to use / as a delimiter, you could escape the pattern using the backslash:
echo preg_replace("/ \/ /g", "", $txt);
We can use multiple symbols as delimiters (eg @ , + , % ). You can also use open and close pairs, such as () , {} , [] , <> .
