从字符串中提取php数字

Question

I need to extract numbers from strings by ignoring 0 's and separate to three string numbers.

Numbers goes from 1 to 26 max

Example:

12 0 25 00 1 : String 1= 12 - String 2= 25 - String 3= 1...

19 0 22 0 16

19 00 2 00 7

3 0 15 0 10

Answer 1

FIXED : Not so obvious, tho. That's the first solution that came to my mind

$string = '02300103024000100';
$output = array();
// First we replace any '00...' string with just '0'
for($a=strlen($string); $a>0; $a--){
   $zero_replace = '';
   while(strlen($zero_replace) < $a) $zero_replace .= '0';
   $string = str_replace($zero_replace,'0',$string);
}
// Now we remove '0' from beginning and end of string (if they exist)
if(substr($string,0,1) == '0') $string = substr($string,1);
if(substr($string,-1,1) == '0') $string = substr($string,0,strlen($string)-1);
// Finally, explode by '0'
$output = explode('0',$string);
print_r($output);

The above should result in something about:

Array ( [0] => 23 [1] => 1 [2] => 3 [3] => 24 [4] => 1 )
