you could just use the floatval function  echo floatval  125 00       125  echo floatval  966 70       966 7  echo floatval  844 011       844 011

You should cast your numbers as floats  which will do this for you    string    42 422005000000000000000000000000   echo  float  string    Output of this will be what you are looking for      42 422005

This is what I use   function TrimTrailingZeroes  nbr        return strpos  nbr        false   rtrim rtrim  nbr  0           nbr      N B  This assumes   is the decimal separator  It has the advantage that it will work on arbitrarily large  or small  numbers since there is no float cast  It also won t turn numbers into scientific notation  e g  1 0E-17

Due to this question is old  First  I m sorry about this   The question is about number xxx xx but in case that it is x xxx xxxxx or difference decimal separator such as xxxx xxxx this can be harder to find and remove zero digits from decimal value          Remove zero digits from decimal value          param string int float  number The number can be any format  any where use in the world such as 123  1 234 56  1234 56789  12 345 67  -98 765 43     param string The decimal separator  You have to set this parameter to exactly what it is  For example  in Europe it is mostly use     instead of          return string Return removed zero digits from decimal value      function removeZeroDigitsFromDecimal  number   decimal sep               explode num   explode  decimal sep   number       if  is array  explode num   amp  amp  isset  explode num count  explode num -1    amp  amp  intval  explode num count  explode num -1       0            unset  explode num count  explode num -1             number   implode  decimal sep   explode num             unset  explode num       return  string   number      And here is the code for test    numbers         1234    1234     -1234    -1234      12 345 67890     12 345 67890      -12 345 678 901234     -12 345 678 901234      12345 000000     12345      -12345 000000     -12345      12 345 000000     12 345      -12 345 000000000     -12 345    foreach   numbers as  number        var dump removeZeroDigitsFromDecimal  number        echo   lt hr gt     n n n      numbers         1234    12324     -1234    -1234      12 345 67890     12 345 67890      -12 345 678 901234     -12 345 678 901234      12345 000000     12345      -12345 000000     -12345      12 345 000000     12 345      -12 345 000000000     -12 345      -12 345 000000 000     -12 345 000000 STRANGE   but also work     foreach   numbers as  number        var dump removeZeroDigitsFromDecimal  number

Simply adding   to your string variable will cause typecast to  float  and removes zeros   var dump   125 00           double 125  var dump   966 70           double 966 7  var dump   844 011          double 844 011  var dump   844 011asdf      double 844 011

num   0 does the trick   echo 125 00   0     125 echo  125 00    0     125 echo 966 70   0     966 7   Internally  this is equivalent to casting to float with  float  num or floatval  num  but I find it simpler

Complicated way but works    num    125 0100    index    num strlen  num -1    i   strlen  num -1  while  index     0        if   num  i      0           num  i              i--            index    num  i        remove dot if no numbers exist after dot  explode   explode       num   if  isset  explode 1    amp  amp  intval  explode 1    lt   0        num   intval  explode 0       echo  num    125 01   the solutions above are the optimal way but in case you want to have your own you could use this  What this algorithm does it starts at the end of string and checks if its 0  if it is it sets to empty string and then goes to the next character from back untill the last character is   0

If you want to remove the zero digits just before to display on the page or template   You can use the sprintf   function  sprintf   g   125 00      125    sprintf   g   966 70      966 7      sprintf   g  844 011     844 011
