Suppose we have such a variable:

$a = "user/category/link/buy/"

We need to make this option from this:

 $a = "usercategorylinkbuy/"

Developments:

 strtr($a, array('/' => '')); //Удаляет абсолютно все / внутри переменной

And if in the variable $ a initially will not be "/", then it should not be added to the end.

If you know that there is exactly / at the end of a variable, then the following code makes sense:

 if(substr($a,-1)=="/") { $a = str_replace("/","",$a); $a .= "/"; } else { $a = str_replace("/","",$a); }

Everything is much simpler.

 trim($a, '/');

True, he will cut off at the beginning, if at the beginning you need to save '/' you can do this:

 '/'.trim($a, '/');
