Similar to another suggestion  except will not obliterate actual zero  if  ltrim  str   0                 str   ltrim  str   0      else        str    0      Or as was suggested  as of PHP 5 3   shorthand ternary operator can be used   str   ltrim  str   0       0

Assuming you want a run-on of three or more zeros to be removed and your example is one string        test str   0002030050400000234892839000239074        fixed str   preg replace   000        test str     You can make the regex pattern fit what you need if my assumptions are off   This help

Ajay Kumar offers the simplest echo   numString  I use these   echo round  val    0005    echo  val   0005        both output 5 echo round  val   00000648370000075845   echo round  val    00000648370000075845          output 648370000075845  no need to care about the other zeroes in the number       like with regex or comparative functions  Works w wo single double quotes   Actually any math function will take the number from the  string  and treat it like so  It s much simpler than any regex or comparative functions  I saw that in php net  don t remember where

Regex was proposed already  but not correctly    lt  php      number    00000004523423400023402340240        withoutLeadingZeroes   preg replace    0          number      echo  withoutLeadingZeroes    gt    output is then   4523423400023402340240   Background on Regex  the   signals beginning of string and the   sign signals more or none of the preceding sign  Therefore  the regex  0  matches all zeroes at the beginning of a string
