How to remove all leading zeroes in a string

Question

If I have a string  00020300504 00000234892839 000239074   how can I get rid of the leading zeroes so that I will only have this  20300504 234892839 239074   note that the number above was generated randomly

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.

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

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

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
