Get first n characters from string

If you want to get simple character from string then can use php default substr function which is quite simple. Belo is the syntax

string substr ( string $string , int $start [, int $length ] )

here

$string is the input string

$start is the non-negative and negative  number. If start is negative means start from the end of string means reverse . If string is non-negative number means start from starting postion.

$length is length of string.

Example

$rest = substr("abcdef", -1);    // returns "f"

Now what if you want to number of word from a sentence ?

Here I am doing with simple function with the help of php wordwrap and explode function.

My custom function is

// php function to get word string with desire lenth
function getSubStrWdLenght($string,$length=10) {
  //check if any blank space with string
  $string = trim($string);

// check if string is not smaller then given length default is 10
  if(strlen($string) > $length) {
    $string = wordwrap($string, $length);
    $string = explode("\n", $string, 2);
    $string = $string[0] ;
  }
  return $string;
}

You simply can pass your string and check result like

$string= "We all are not alone";
$result = getSubStrWdLenght($string,1);

echo'===>'.$result;

It should return “We”
