Using a PHP function to make a viable file name with variables

[woocha]

Hey Guys..

 

I have a quick questions here about user input forms.  I have a form that a user fills out and I want them to be able to insert a phrease of 2-5 words not just one word (example: I Love PHPFreaks).  The field is turned into a viariable called $notes the variable is then turned into a file name such as $notes.txt.  I want it so that the 2-5 word phrase can be turned into I_Love_PHPFreaks  This way when the file(I_Love_PHPFreaks.txt) is on the server, it can still work.  Is there a function for this?

 

Thank you

$string = "I Love PHPFreaks";

$newString = str_replace(" ", "_", $string); //replaces all spaces with the underscore

echo $newString;

// writes I_Love_PHPFreaks

What happens if they use:

"I_Love_PHPFreaks."

...

Remember to strip out anything except spaces and letters/numbers.

$string = "I Love PHPFreaks";

$newString = str_replace(" ", "_", $string); //replaces all spaces with the underscore

echo $newString;

// writes I_Love_PHPFreaks

 

Thanks a lot man... I really appreciate it.

do you mean with strip_tags?  how would I use that or should I use someting else?

$string = "I Love PHPFreaks";

$newString = str_replace(" ", "_", $string); //replaces all spaces with the underscore

echo $newString;

// writes I_Love_PHPFreaks

 

 

Would this work as well?

$newString = str_replace(" ", "aeiou", $string); //replaces all spaces with the underscore

 

meaning, Can I replace the space with more than one character if I had or wanted to?
