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

Answer 1

I don't think preg_replace is the answer.. old thread but just happen to looking for this today. ltrim and (int) casting is the winner.

"; 
 echo $fixed_str1 . " Fix1";
 echo "
"; 
 echo $fixed_str2 . " Fix2";
 echo "
";
 echo $fixed_str3 . " Fix3";
 echo "
";
 echo $actualInt . " Actual integer in string";

 //output

 0000001123000 Origina
 1123 Fix1
 1123000 Fix2
 1123000 Fix3
 1123000 Actual integer in tring
