windows - PHP regex to limit new lines to a maxmium of two -

I'm using it, but it's a new line's single code to & lt; Br / & gt; & Lt; Br / & gt;

  function nl2br2 ($ string) {$ string = preg_replace ('/ (\ r \ n) {2,} /', '
 br / & gt; & Lt; br / & gt; ', $ string); // $ string = preg_replace ('/ [\ r \ n] /', '
', $ string); Return $ string; }  

It happens with the first pattern.

OK, I suspect that your input may not be '/ r / n', but Only '\ n'. In this case, you should find out your regex that: '/ (\ r? \ N) {2,} /'

Your code may be:

  function nl2br2 ($ string) {$ string = preg_replace ('/ (\ r? \ N) {2,} / ',' 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
  Return $ string; }  

It helps.
