$string= 'abcdefg'; echo $string[4];

Hello community,

 

Does anyone know where exactly in the php manual is explained the next functionality:

 

$string= 'abcdefg';

echo $string[4];

 

...this works and outputs: 'e'

 

this look like some sort of array, but I just can find it explained in the php manual.

 

Any link for an exact explanation will be apreciated.

 

Thank you.

Angel

when used on a string, the index notation refers to the character in that string.  'e' is the 5th character in the string, which is index 4 (since indexes start at 0).  $string[0] would be 'a', etc.

It's simple. It's outputting byte #4 in the string. But php starts counting from 0.

 

Like:

 

a = 0

b = 1

c = 2

d = 3

e = 4

 

In that example you gave.

Thank you for your fast reply.

 

I do understand how this concept works, but would this be in the PHP manual?

[akitchin]

it is, in the variables section.  is there any particular reason you want to find it in the manual, despite understanding how it works?

there is not exactly a particular reason for this issue, I just wanted to find it in the manual that is pretty much it. perhaps self-satisfaction(maybe laziness to find it myself). i'll look in the variables section, thank you. = )
