[SOLVED] convert all \n and \t to spaces, and replace 2 spaces with 1

[scarhand]

I need a regex that will preg_replace all "\n" (linebreaks) and "\t" (tabs) to spaces. After this is done, I want it to convert 2 spaces "  " into 1 space " ".

 

I know how to preg_replace the "\n" and "\t", but not the 2 spaces into 1. I imagine it would have something to do with {2} or something like that.

I imagine it would have something to do with {2} or something like that.

you are about there. but that says match 2 spaces. if there are 2 or more spaces, you can use {2,}

I think what you really want to use here is trim().

fabrydesign, keep in mind that trim only eliminates the initial / trailing character(s) in question, it will not effect those deeper within the string itself.

I'm using this:

 

preg_replace('[ \t\n\r]+', ' ', $string);
