Hi, everyone

I am in a problem that

assume

variable a=“123”

I want to keep 1 2 3 in different variable as like
a[0]=1
a[1]=2
a[2]=3

Any idea will be very helpful to me.

First divide count the number of digits
if it is 3 digits,
loop through with divide by 100, take 1 as into array with index0
next divide by 10 take 2 as into array with index1
remaing number into array with index 2

a=00111100011

Hello,

you can do it in this way:

$var = '12301245675';
$arr = array();

for ($i = 0; $i < strlen($var); $i++){
	$arr[] = $var[$i];
}

echo '<pre>';
print_r($arr);

The output will be:

Array
(
    [0] => 1
    [1] => 2
    [2] => 3
    [3] => 0
    [4] => 1
    [5] => 2
    [6] => 4
    [7] => 5
    [8] => 6
    [9] => 7
    [10] => 5
)

Not withstanding the solutions already posted, just to say that you already can easily access each char in a string.


$a="123"
echo $a[1] // 2

This might be helpful if the length of $a is set and importantly, is $a actually a string ‘123’ or is it an int 123 (else cast it to a string with)


$a = (string) 123;

Man page on strings might be helpful to you too.

Wandering off the topic a bit here, but pay particular attention if these numbers/string start with a 0 (zero) and you use them as integers later in your programme.
