php - Remove trailing zeros from a string -

I want to zoom back to zero according to the following rules:

• input number is always 4 The decimal place will be
• The output number should always be between 2 and 4 decimal
• If the last two digits after the decimal is zero, then remove both of them < Li> If the last digit is a zero after the decimal, then delete it

  Example:

  • 1.0000 - & gt; 1.00
  • 1.4000 - & gt; 1.40
  • 1.4100 - & gt; 1.41
  • 1.4130 - & gt; 1.413
  • 1.4136 - & gt; I have considered the following:

      if (substr ($ number, -2) == '00') return substagram ($ number, 0, 4); If (substr ($ number, -1) == '0') return substorage ($ number, 0, 5); Return number $;   
     Is there any better way to do this?   
     
     
     I think this should work:  
      return preg_replace ('/ 0 {1,2} $ /', '', $ number); $ String = array ('1.4000', '1.4100', '1.4130', '1.4136', '1.4001', '1.0041'); Forex currency ($ wire as $ number) {resonant "$ number -> Preg_replace ('/ 0 {0}} $ /', '', $ number). "\ N"; }   
     produces:  
      1.4000 - & gt; 1.40 1.4100 - & gt; 1.41 1.4130 - & gt; 1.413 1.4136 - & gt; 1.4136 1.4001 - & gt; 1.4001 1.0041 - & gt; 1.0041
