Extract numeric values from string
Many time we have a mixed sentence which contains string and numbers. If we want to separate string and numbers then we can do easily with php default ctype_digit function. Here i am writing a simple function using ctype_digit to perform this action.
function getCharNumber($string,$whatNeed,$numSprator=' ',$stringSprator=' '){
$characters = '';
$numbers = '';
$str = false;
for($count=0; $count<strlen($string); $count++){
if(ctype_digit($string[$count])){
if($str)
$numbers .= $numSprator;
$numbers .= $string[$count];
$str = false;
}else{
if(!$str)
$characters.= $stringSprator;
$characters .= $string[$count];
$str = true;
}
}
if($whatNeed=='char')
return $characters;
elseif($whatNeed=='num')
return $numbers;
else
return "Oops something wrong!!";
}
Now check result of this function
//your string $string = "Your have 5 cart and each cart includes 89 items. You need 10 more itmes with 2 carts fro Rs. 550.89."; //$whatneed must be 'char' if string required and 'num' if digit required $result = getCharNumber($string,'num'); echo "your string is : '$string' <br>"; echo $result;
Result should be like as below
your string is : ‘Your have 5 cart and each cart includes 89 items. You need 10 more itmes with 2 carts fro Rs. 550.89.’
5 89 10 2 550 89
NOTE: Keep in mind it will return numeric string not an numbers like integer or float . You can see output of above example it will return 550 and 89 instead of 550.89. Means numeric string not an numeric type value.
