php - copying some part of string

Question

Hi guys, how can i get some part of string (in symbols). For example:

$string = 'one two three';
$numSymbols = 7;
 %what should I do%
$res_string = 'one two';

Help, please.

Answer 1

You are looking for the substr function, I'd say.

In your case, here is an example :

$string = 'one two three';
$numSymbols = 7;

$res_string = substr($string, 0, $numSymbols);
var_dump($res_string);

And you'll get :

string 'one two' (length=7)

Parameters :

• the string to extract from
• the position of the first character ; ie, 0, if you want to start at the beginning of the string
• the number of characters you want : 7

Answer 2

use php method substr:

$string = 'one two three';
$numSymbols = 7;
$res_string = substr($string, 0, $numSymbols);

Answer 3

You should be using substr()

Example:

$string = 'one two three';
$res_string = substr($string, 0, 7);// $res_string == 'one two'
