note 57271 rejected from function.trim by betz

Note Submitter: foxlance_g at yahoo dot com ---- i have this project that parses html to extract some values, like the one from jobsites. now the problem is the filed im to extract looks like this on the source codes name surname i did a trim, but it only deals with the front and end of the string, not on the inside, i formulated a str_replace function, but if im going to replace all ' ' (whitespaces), the values will merges 'val1val2' right? how can i delete all unnecessary whitespaces, and leave only one in between words in a string, like if var='lance vincent' var should be var='lance vincent'
