Exploding a number and separate it by a space

Question

I want to explode a string or an integer and separate it by a space.

E.g., I have this int 12345678, and I want its numbers to become like 123 45678. I want the first three numbers separated. Can someone give me a clue or hint in how to achieve this, like what function to use in PHP? I think using an explode will not work here because the explode function needs a separator.

You can use substr_replace() - Replace text within a portion of a string.

echo substr_replace(1234567, " ", 3, 0); // 123 4567

You could use substr() :

$str = "12345678" ;
echo substr($str,0,3)." ".substr($str, 3); // "123 45678"

Also works with an integer :

$int = 12345678 ;
echo substr($int,0,3)." ".substr($int, 3); // "123 45678"

I understand the first `substr` `0` means the start and `3` means the length. But how about the second? why that method only have one parameter? – hihihihi Feb 08 '18 at 11:30
@nethkennnnn The second starts at 3 and get value until the end (no argument). – Syscall Feb 08 '18 at 11:31
One more question @Syscall. How do we count it? Is the count same as an `array` like it starts with `0`. Or the `"` is counted as an element inside it? – hihihihi Feb 08 '18 at 11:41
@nethkennnnn Yes, indices starts with 0. – Syscall Feb 08 '18 at 11:42
@nethkennnnn For start, length using 1, 2, 3... – Syscall Feb 08 '18 at 11:42

This problem will solve by using substr().

The substr() function returns a part of a string.

Syntax: substr(string,start,length)

Example:

$value = "12345678";
echo substr($value,0,3)." ".substr($value, 3);

Output: 123 45678

You may get better understand from here.

How does this differ from @Syscall answer? – Lawrence Cherone Feb 08 '18 at 11:47
The comment is quite similar to @syscall's comment. Now I try to add some description for better understand. – Md Rasel Ahmed Feb 08 '18 at 12:08
