Replacing repeating occurances of spaces

[dlgilbert]

I've been searching for this answer for quite awhile and can't find an appropriate function to do it.

I want to replace any multiple occurances of the [space] character with the non-breaking space HTML symbol. I can't simply replace all spaces in the string with the symbol because then it would replace all the spaces between words. I only want to use it if there are two or more spaces in sequence.

Before I go write some bizarre algorithm to do this, can anyone point me to a function that could possibly do this automatically?

Thanks!

Use ereg_replace. Regular expression rule the world.
ereg_replace("[[:space:]]+", " ", $string);
This will also replace tabs etc however, you can tweak this as you wish; read the manual for more info.
