In this session we will study the looping statements in php such as for and while loop.
- To study the looping statements follow the steps given below :
-
- Install the Xampp server , if it is already installed then go to xampp folder .
-
- Inside this xampp folder you will have htdocs folder .
-
- In this htdocs folder create a new folder say s4
-
- Inside this s4 folder create a new file say index.php and open it with Notepad++ or any other text editor.
-
- So to implement the loops write the following code in index.php file :
<html>
<body>
<h1>This is the for loop</h1>
<?php
for($i=0;$i<=10;$i++)
{
echo 'Number ' .$i .'<br />';
}
?>
<h1>This is the while loop</h1>
<?php
$i=0;
while($i <= 10){
echo 'number '.$i.'<br />';
$i++;
}
?>
</body>
</html>
-
- You will have the following view of your Notepad++ window :
-
- Now open up the browser and enter the following url in the address bar : http://localhost//s4//index.php
-
- You will have the output as shown below :
- Implement Loops in php using Json
-
- Create an new folder in the htdoc say s5 inside that create an new file called as index.php and open it with notepad++ and write the given code in it
<?php
$jsondata = file_get_contents("movies.json");
$json = json_decode($jsondata,true);
?>
<!DOCTYPE html>
<html>
<head>
<title>My Movies</title>
</head>
<body>
<div id="container">
<h1>My Favorite Movies</h1>
<ul>
<?php
//echo $json['movies'][0]['title'];
foreach($json['movies'] as $key => $value){
echo '<h4>'.$value['title'].'</h4>';
echo '<li>Year: '.$value['year'].'</li>';
echo '<li>Genre: '.$value['genre'].'</li>';
echo '<li>Director: '.$value['director'].'</li>';
}
?>
</ul>
</body>
</html>
-
- Now in the same s5 folder create another file say movies.json , open it with notepad++ and write the given code in it :
{
"movies": [
{
"title": "The Godfather",
"year": "1972",
"genre": "Drama",
"director": "Francis Ford Copolla"
},
{
"title": "Superbad",
"year": "2007",
"genre": "Comedy",
"director": "Greg Mottola"
},
{
"title": "The Departed",
"year": "2006",
"genre": "Drama",
"director": "Martin Scorsese"
},
{
"title": "Saving Private Ryan",
"year": "1998",
"genre": "Action",
"director": "Steven Spielberg"
},
{
"title": "The Expendables",
"year": "2010",
"genre": "Action",
"director": "Sylvester Stallone"
}
]
}
-
- The window look like as shown below :
-
- Now open up the browser and enter the url as http://localhost/s5/index.php
-
- You will have the following output :
-
- You can add the css in head section
<style>
h1{text-align:center;}
h4{margin:0;padding:5px;background:#f4f4f4;}
li{list-style:none;padding-left:5px;}
#container{width:600px;margin:auto;overflow:hidden;}
</style>
-
- Now run the project and you will have the following output window :-
- Thus we have learnt implementing loops in php using json.
