✅ Step-by-Step Guide:
1. Convert Array to JSON with json_encode() :
// Create PHP array
$user = [
'name' =〉 'Sarah',
'age' =〉 28,
'active' =〉 true
];
// Convert to JSON string
$json = json_encode($user);
// Output: {"name":"Sarah","age":28,"active":true}
echo $json;
2. Convert JSON to Array with json_decode() :
// JSON string
$json = '{"name":"Sarah","age":28,"active":true}';
// 1. Decode to PHP OBJECT (default)
$userObj = json_decode($json);
echo $userObj-〉name;
// "Sarah"
echo $userObj-〉age;
// 28
// 2. Decode to ASSOCIATIVE ARRAY (add true)
$userArray = json_decode($json, true);
echo $userArray['name']; // "Sarah"
echo $userArray['age']; // 28
3. Common Errors & Fixes:
// ERROR: Malformed JSON
$badJson = "{'name':'Sarah'}"; // Uses single quotes
// Check for errors
$data = json_decode($badJson);
if (json_last_error() !== JSON_ERROR_NONE) {
echo "JSON error: " . json_last_error_msg();
}
// FIX: Use double quotes
$goodJson = '{"name":"Sarah"}';
✅ Why Use
json_encode() and json_decode() ?
Data Interchange: Easily convert PHP arrays to JSON strings for web APIs or databases.
Cross-Language Compatibility: JSON is a universal format, making it ideal for integrating
PHP with other languages.
Efficiency: These functions are optimized for performance, ensuring quick data handling.
✅ Pro Tips:
Always Use Double Quotes: JSON requires double quotes for keys and values.
Check for Errors: Use json_last_error() and json_last_error_msg() to debug
issues.
Use Associative Arrays: When decoding, set the second parameter of json_decode() to
true for associative arrays.
Validate JSON: Before decoding, ensure the JSON string is valid to avoid runtime errors.
