Separate alphabets and numbers from a string - php

Question

$str = 'ABC300';
How I can get values like
$alphabets = "ABC";
$numbers = 333;

Answer 1

I have a idea , first remove numbers from the string and save in a variable. then remove alphabets from the $str variable and save. try the code
$str = 'ABC300';
$alf= trim(str_replace(range(0,9),'',$str));//removes number from the string
$number = preg_replace('/[A-Za-z]+/', '', $str);// removes alphabets from the string
echo $alf,$number;// your expected output

Answer 2

Try something like this (it's not that fast)...
$string = "ABCDE3883475";
$numbers = "";
$alphabets = "";
$strlen = strlen($string);
for($i = 0; $i <= $strlen; $i++) {
$char = substr($string, $i, 1);
if(is_numeric($char)) {
$numbers .= $char;
} else {
$alphabets .= $char;
}
}
Then all numbers should be in $numbers and all alphabetical characters should be in $alphabets ;)

A way to do that is to find all digits and use the array to replace original string with the digits inside.
For example
function extractDigits($string){
preg_match_all('/([\d]+)/', $string, $match);
return $match[0];
}
$str = 'abcd1234ab12';
$digitsArray = extractDigits($str);
$allAlphas = str_replace($digitsArray,'',$str);
$allDigits = '';
foreach($digitsArray as $digit){
$allDigits .= $digit;
}
