How do do a str_replace on this?

I'm trying to do a string replace on this phrase:  "all 6 news updates" 

... keeping in mind that the number 6 could be 30 or 100 or 1000 or whatever...  How do I go about that?  I know how when the text is static but since the number is changing, I dont. 

Thanks. 

You'll want to use regex

$str = "all 6 news updates";
$number = preg_replace('/all (\d+) news updates/', '$1', $str);

echo "Echo the number is: $number";

What do you want replace the number with?

Actually, I'm not wanting to replace the number.  I want to find all instances of that entire phrase (regardless of the number that I find) and blank it out. 

$description=str_replace('all 6 news updates','',$description)

...keeping in mind that the number could be anything, which is why I can't use the code as I've just written it. 

Thanks!

$str = "blah blah blah blah

all 6 news updates

blah blah blah 

all 999 news updates

blah";

$str = preg_replace('/all (\d+) news updates/', '', $str);

echo nl2br($str);

$str = "blah blah blah blah

all 6 news updates

blah blah blah 

all 999 news updates

blah";

$str = preg_replace('/all (\d+) news updates/', '', $str);

echo nl2br($str);

Thank you, sir.  Worked great!
