[SOLVED] extract numeric values from string

[vinpkl]

hi all

 

i have a string like "123 abc 45".

 

i am using the below code to extract numeric from string. The result i get  for numeric value is "12345".

 

How can i get the result as "123" and "45" as separate two keywords.

 

<?php 
$string = "123 abc 45"; 
$chars = ''; 
$nums = ''; 
for ($index=0;$index<strlen($string);$index++) { 
    if(isNumber($string[$index])) 
        $nums .= $string[$index]; 
    else     
        $chars .= $string[$index]; 
} 
echo "Chars: $chars<br>Nums: $nums"; 

function isNumber($c) { 
    return preg_match('/[0-9]/', $c); 
} 
?>

hi Andy

 

i saw the link you gave but they have no where explained how to separate the two numeric values that we get.

what they are checking is about numeric and alpha numeric values. that i have already done.

<?php 
$string = "123 abc 45"; 
$chars = ''; 
$nums = ''; 
for ($index=0; $index<strlen($string); $index++) { 
    if( ctype_digit($string[$index]) )
    {
        if ($str)  $nums .= ' ';
          $nums .= $string[$index];
          $str   = False;
     }else{
        if (!$str)  $chars.= ' ';
          $chars .= $string[$index];
          $str    = True;
    }
} 
echo "Chars: $chars<br >Nums: $nums"; 
?>

preg_match_all("%[0-9]{1,}%",$string,$matches);


foreach($matches[0] as $number)

{

    echo $number."<br>";

}

?>
