Note Submitter: M. Kristall ---- Karl Kangur, You can also use the "s" switch on your RE to treat new lines as part of the same line. For example, <?php $string = " once upon a time"; echo preg_replace ( array ( '/\s+/s', // Any space(s) '/^\s+/s', // Any space(s) at the beginning '/\s+$/s' // Any space(s) at the end ), array ( ' ', // ... one space '', // ... nothing '' // ... nothing ), $string ); // outputs 'once upon a time' ?> (Note: php.net uses non-breaking spaces followed by spaces, repetitively. Browsers ignore multiple white space - one nbsp counts as a space, so unless the next one is also an nbsp, it is ignored. <pre>...</pre> could be used in this case thus solving the problem and removing any need for nbsp at all.)
