<?php

 

class Person {

private $name;

function __construct($name) {

$this->name = $name;

}

 

function setName($newName) {

$this->name = $newName;

}

 

function getName() {

return $this->name;

}

}

 

$brian = new Person("Brian Mischook"); // create object

$name = $brian->getName(); // get name variable from object

echo "Brian's full name: " . $name . '<br>';

 

// Need to add the code here. It must check the returned name length and print at logic output according to the name length

 

?>

 

 

By using functions like strlen(), stripos() and substr(), I need to add code to the script that checks the length of the name property and if it is more than 10 characters long, the name property must be set to only be the first name. The class must not be changed.

 

Exemple: Brian Full Name: Brain Mischoock

Braian First Name: Brain

 

Some suggestions?

You could do like this:

 

if (strlen($name) > 10) {
$exploded = explode(' ', $name); // Split name by spaces and put into array
$name = $exploded[0]; // $name now only contains the first name
}

public function nameLength(){
return strlen($this->name);
}

 

or, but not recommended in many situations:

public function getLength($var){
return strlen($this->{$var});
}

 

first case to use:

$person = new Person('dani33l_87');
echo $person->nameLength();

 

In the latter case to use:

$person = new Person('dani33l_87');
echo $person->getLength('name');

if(strlen($p->getName()) > 10) {
if(str_word_count($p->getName()) > 1) {
$pos = strpos($p->getName(), ' ');
// if($pos) {
$name = substr($p->getName(), 0, $pos);
// }
}
else {
$name = substr($p->getName(), 0, 10);
}
$p->setName($name);
}

echo $p->getName();
// Result: PHPFreaks

Thank you very much for your help guys.

The class must not be changed.

 

I just want to add that this functionality should indeed be in the Person class not outside of it, otherwise you will just be copying code around your project whenever you need the person's first name.

 

class Person {
  private $fullName;
  
  public function __construct($fullName) {
    $this->fullName = $fullName;
  }
  
  public function getFullName() {
    return $this->fullName;
  }
  
  public function getFirstName() {
    $words = str_word_count($this->getFullName(), 1);
    return $words[0];
  }
}

 

Also just returning the first word could as easily be 'Dr.' which is not what was intended.

Without changing the class:

<?php
class Person {
private $name;
function __construct($name) {
 $this->name = $name;
}


function setName($newName) {
 $this->name = $newName;
}


function getName() {
 return $this->name;
}
}


class Person2 extends Person{
public function nameLength(){
 return strlen($this->getName());
}
}


$person = new Person2('the name');
echo $person->nameLength();
?>

 

<?php
class Person {
private $name;
function __construct($name) {
 $this->name = $name;
}


function setName($newName) {
 $this->name = $newName;
}


function getName() {
 return $this->name;
}
}
$person = new Person2('the name');
echo strlen($this->getName());
?>
