Regular Expression help

[Anon]

I am looking for a simple regular expression to find two consecutive words in a string.

In the string

'The cat is is blue'

the repeated is would be found by the regular expression. I tried

if ( ereg( "(([a-zA-Z]+)[ \t\n\r]){2}", $search, $match))

but it doesnt work. Can anyone help?

Here's an off-the-wall idea... (TMTOWTDI)

explode the string into an array, then step through the array comparing the current element to the next one. If you get a dupe, just unset that array element. Then implode the array back into a string.

granted, its ugly, but workable. 😉
