7. Strings (PHP)

A string in PHP is a sequence of characters (text).

$name = "Aditya";
echo $name;

🔹 1. String Functions (Important Built-in Functions)

PHP provides many built-in functions to work with strings.

📌 Common String Functions

$str = "Hello World";// Length of string
echo strlen($str); // 11// Convert to lowercase
echo strtolower($str); // hello world// Convert to uppercase
echo strtoupper($str); // HELLO WORLD// First letter capital
echo ucfirst("hello"); // Hello// First letter of each word
echo ucwords("hello world"); // Hello World// Reverse string
echo strrev("Hello"); // olleH// Find position
echo strpos($str, "World"); // 6// Replace text
echo str_replace("World", "PHP", $str); // Hello PHP

🔹 2. String Manipulation

String manipulation means modifying or working with strings.

📌 Concatenation (Joining Strings)

$first = "Hello";
$second = "World";echo $first . " " . $second; // Hello World

📌 Substring

echo substr("Hello World", 0, 5); // Hello

📌 Trim (Remove Spaces)

$str = "  Hello  ";
echo trim($str); // "Hello"

📌 Compare Strings

if ("apple" == "apple") {
    echo "Same";
}

🔹 3. Explode / Implode

These are very important for working with arrays and strings.

📌 explode() → String ➝ Array

Splits a string into an array.

$str = "apple,banana,mango";
$arr = explode(",", $str);print_r($arr);

👉 Output:

Array ( [0] => apple [1] => banana [2] => mango )

📌 implode() → Array ➝ String

Joins array elements into a string.

$arr = ["apple", "banana", "mango"];
$str = implode(",", $arr);echo $str; // apple,banana,mango

🔹 4. Regular Expressions (Regex)

Regex is used to match, search, or replace patterns in strings.

PHP uses functions like:

preg_match()
preg_replace()
preg_match_all()

📌 preg_match() (Check Pattern)

$str = "Hello123";if (preg_match("/[0-9]/", $str)) {
    echo "Number found";
}

📌 preg_replace() (Replace Pattern)

$str = "Hello123";echo preg_replace("/[0-9]/", "", $str);
// Output: Hello

📌 preg_match_all() (Find All Matches)

$str = "abc123xyz456";preg_match_all("/[0-9]+/", $str, $matches);print_r($matches);

📌 Common Regex Patterns

Pattern	Meaning
`/[0-9]/`	Any number
`/[a-z]/`	Lowercase letters
`/[A-Z]/`	Uppercase letters
`/^[a-z]+$/`	Only lowercase letters
`/^\d+$/`	Only numbers
`/^[a-zA-Z0-9]+$/`	Alphanumeric

🎯 Real Example (Form Validation)

$email = "test@gmail.com";if (preg_match("/^[\w\.-]+@[\w\.-]+\.\w+$/", $email)) {
    echo "Valid Email";
} else {
    echo "Invalid Email";
}

🚀 Summary

String Functions → Ready-made tools (strlen, strtoupper, etc.)
String Manipulation → Modify strings (concat, substr, trim)
explode() / implode() → Convert between string ↔ array
Regex → Advanced pattern matching & validation

Auto grading system (PHP)

I’ve created a basic auto-grading PHP system for you in the canvas.

🔍 What this system does:

Takes student answers via form
Compares with correct answers
Assigns marks automatically
Displays total score

🚀 How to use it:

Copy the code into a file like:
auto-grade.php
Run in:
- XAMPP (localhost/auto-grade.php)
- Your website (SOA Technology 😉)
Students enter answers → system checks instantly ✅

<?php
// ==============================
// PHP Auto Grading System
// ==============================

$totalMarks = 0;

// Function to check answer
function check($studentAnswer, $correctAnswer, $marks) {

        $totalMarks += $marks;
        return "Correct (+$marks)";
    } else {
        return "Wrong (0)";
    }
}

// ==============================
// Student Answers (via form)

$q3 = $_POST['q3'] ?? '';
$q4 = $_POST['q4'] ?? '';
$q5 = $_POST['q5'] ?? '';

// ==============================
// Correct Answers (Expected Output)
// ==============================
$answers = [
    "q1" => "150",      // sum of numbers
    "q2" => "5",        // count of fruits
    "q3" => "Aditya",   // name output
    "q4" => "90",       // highest marks
    "q5" => "3"         // total students
];

// ==============================
// Checking Answers
// ==============================
$result = [];
$result['q1'] = check($q1, $answers['q1'], 10);

$result['q4'] = check($q4, $answers['q4'], 10);
$result['q5'] = check($q5, $answers['q5'], 10);

// ==============================
// Display Result
// ==============================
echo "<h2>Result</h2>";

foreach ($result as $q => $res) {
    echo strtoupper($q) . ": " . $res . "<br>";
}

echo "<h3>Total Marks: $totalMarks / 50</h3>";
?>

6. Arrays (PHP)

Arrays in PHP are used to store multiple values in a single variable instead of creating separate variables.

👉 Example:

$fruits = ["Apple", "Banana", "Mango"];

🔹 1. Indexed Arrays

These arrays use numeric indexes (0, 1, 2…)

✅ Example:

$colors = ["Red", "Green", "Blue"];echo $colors[0]; // Red
echo $colors[1]; // Green

✅ Using loop:

for ($i = 0; $i < count($colors); $i++) {
    echo $colors[$i] . "<br>";
}

👉 Best for: lists of items

🔹 2. Associative Arrays

These arrays use named keys instead of numbers

✅ Example:

$student = [
    "name" => "Aditya",
    "age" => 22,
    "course" => "BCA"
];echo $student["name"]; // Aditya

✅ Loop:

foreach ($student as $key => $value) {
    echo "$key: $value <br>";
}

👉 Best for: structured data (like objects)

🔹 3. Multidimensional Arrays

Arrays inside arrays (used for complex data)

✅ Example:

$students = [
    ["Aditya", 22, "BCA"],
    ["Rahul", 21, "BSc"],
    ["Neha", 23, "MCA"]
];echo $students[0][0]; // Aditya
echo $students[1][2]; // BSc

✅ Loop:

foreach ($students as $student) {
    echo $student[0] . " - " . $student[2] . "<br>";
}

👉 Best for: tables / database-like data

🔹 4. Important Array Functions

✅ 1. sort() → Sort values (ascending)

$numbers = [3, 1, 5, 2];
sort($numbers);
print_r($numbers);

✅ 2. rsort() → Descending sort

rsort($numbers);

✅ 3. asort() → Sort associative array by value

$age = ["Aditya" => 22, "Rahul" => 20];
asort($age);

✅ 4. ksort() → Sort by key

ksort($age);

✅ 5. array_merge() → Combine arrays

$a = ["Red", "Blue"];
$b = ["Green", "Yellow"];$result = array_merge($a, $b);
print_r($result);

✅ 6. array_filter() → Filter values

$numbers = [1, 2, 3, 4, 5];$even = array_filter($numbers, function($n) {
    return $n % 2 == 0;
});print_r($even);

✅ 7. array_map() → Modify each value

$numbers = [1, 2, 3];$square = array_map(function($n) {
    return $n * $n;
}, $numbers);print_r($square);

🎯 Summary

Type	Use Case
Indexed Array	Simple lists
Associative Array	Key-value data
Multidimensional Array	Complex/nested data

💡 Teaching Tip (for your students)

Explain like this:

Indexed = List 📋
Associative = Dictionary 📖
Multidimensional = Table 📊
