The PHP File
PHP has some built-in functions to handle JSON.
Objects in PHP can be converted into JSON by using the PHP function json_encode():
Step 1:
Create index.html file and create below html code in it.
<h2 id="demo1"></h2>
Step 2:
Create php file to access json data.
PHP Array
Arrays in PHP will also be converted into JSON when using the PHP function json_encode():
demo_json.php
<?php
$myArr = array("John", "Mary", "Peter", "Sally");
$myJSON = json_encode($myArr);
echo $myJSON;
?>
The Client JavaScript
Here is a JavaScript on the client, using an AJAX call to request the PHP file from the array example above:Use JSON.parse() to convert the result into a JavaScript array:
<script>
var xmlhttp = new XMLHttpRequest();
xmlhttp.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
var myObj = JSON.parse(this.responseText);
document.getElementById("demo1").innerHTML = myObj[2];
}
};
xmlhttp.open("GET", "demo_json.php", true);
xmlhttp.send();
</script>
