echo minus something

[Blade Maker]

I am calling stuff from my database, and I want to know if when I echo it if I can take out certain characters when I echo it, not from the database but only in the echo, if so how?

So basically you want that the display displays something different that the database contains? Yes you can, if you have some very well defined rules.

For example we could replace all the A with a B:

echo str_replace("A","B","AAAAAAA");

You may also try regular expressions in case.

a nice filter solution could be something like so

// Basically this filters the Variable.
// ctype_alnum Simply checks if the variable doesn't contain alpha/numeric chars
// ereg_replace simply you replace _ with nothing in the $var
// ^this is so it will not recognize the _ to be a issue and then allows _, Alpha and Numeric.
  $var = (!ctype_alnum(ereg_replace('[_]', '', $var)) ? $var : '' ;
 echo $var;

 

Hope this helps
