if, else, elseif, and switch.

2. `if`, `else`, and `elseif` Statements
<?php
$score = 85;
if ($score >= 90) {
echo "Grade: A";
} elseif ($score >= 80) {
echo "Grade: B";
} elseif ($score >= 70) {
echo "Grade: C";
} else {
echo "Grade: F";
}
?>
• The condition inside if() must return true or false.
• You can chain multiple conditions using elseif.
---
3. `switch` Statement
• Good for checking a variable against multiple possible values.
<?php
$day = "Tuesday";
switch ($day) {
case "Monday":
echo "Start of the week!";
break;
case "Friday":
echo "Weekend is near!";
break;
case "Sunday":
echo "Rest day!";
break;
default:
echo "Just another day.";
}
?>
• Each case must end with a break to avoid fall-through.
---
4. Loops in PHP
Loops allow repeating code multiple times.
---
5. `while` Loop
<?php
$i = 0;
while ($i < 5) {
echo "Number: $i<br>";
$i++;
}
?>
• Repeats while the condition is true.
---
6. `do...while` Loop
<?php
$i = 0;
do {
echo "Count: $i<br>";
$i++;
} while ($i < 3);
?>
• Executes at least once even if the condition is false initially.
---
7. `for` Loop
<?php
for ($i = 1; $i <= 5; $i++) {
echo "Line $i<br>";
}
?>
• Most commonly used loop with initializer, condition, and increment.
---
8. `foreach` Loop
• Used to iterate over arrays.
<?php
$colors = array("red", "green", "blue");
foreach ($colors as $color) {
echo "Color: $color<br>";
}
?>
• Also works with key-value pairs:
<?php
$person = array("name" => "Ali", "age" => 28);
foreach ($person as $key => $value) {
echo "$key: $value<br>";
}
?>
---
9. Control Keywords
• break – Exit a loop or switch.
• continue – Skip current iteration and go to the next.
for ($i = 1; $i <= 5; $i++) {
if ($i == 3) continue;
echo "$i<br>";
}
---
10. Summary
• Conditional logic (if, else, switch) helps make decisions.
• Loops (for, while, foreach) help automate repetitive tasks.
• Control flow is critical for building dynamic applications.
---
Exercise
• Write a PHP script that prints numbers 1 to 20, but skips multiples of 3 using continue, and stops completely if the number is 17 using break.

#PHP #ControlStructures #Loops #PHPTutorial #BackendDevelopment
https://t.me/Ebooks2023$name = "Ali";
• Integer – Whole numbers.
$age = 30;
• Float (Double) – Decimal numbers.
$price = 19.99;
• Boolean – true or false.
$is_active = true;
• Array – Collection of values.
$colors = array("red", "green", "blue");
• Object, NULL, Resource – Used in advanced scenarios.
---
2. Type Checking Functions
var_dump($variable); // Displays type and value
is_string($name); // Returns true if $name is a string
is_array($colors); // Returns true if $colors is an array
---
3. PHP Operators
• Arithmetic Operators
$a = 10;
$b = 3;
echo $a + $b; // Addition
echo $a - $b; // Subtraction
echo $a * $b; // Multiplication
echo $a / $b; // Division
echo $a % $b; // Modulus
• Assignment Operators
$x = 5;
$x += 3; // same as $x = $x + 3
• Comparison Operators
$a == $b // Equal
$a === $b // Identical (value + type)
$a != $b // Not equal
$a > $b // Greater than
• Logical Operators
($a > 0 && $b > 0) // AND
($a > 0 || $b > 0) // OR
!$a // NOT
---
4. String Concatenation
• Use the dot (.) operator to join strings.
$first = "Hello";
$second = "World";
echo $first . " " . $second;
---
5. Summary
• PHP supports multiple data types and a wide variety of operators.
• You can check and manipulate data types easily using built-in functions.
---
Exercise
• Create two variables: one string and one number. Perform arithmetic and string concatenation, and print the results.
---

https://t.me/Ebooks2023<?php echo "Hello, World!"; ?>
• Every PHP statement ends with a semicolon (;).
4. Basic Output with echo and print
<?php echo "This is output using echo"; print "This is output using print"; ?>
• echo is slightly faster; print returns a value.
5. PHP Variables
• Variables start with a dollar sign ($) and are case-sensitive.
<?php $name = "Ali"; $age = 25; echo "My name is $name and I am $age years old."; ?>
6. PHP Comments
// Single-line comment # Also single-line comment /* Multi-line comment */
7. Summary
• PHP is a server-side scripting language used to build dynamic web applications.
• Basic syntax includes echo, variables with $, and proper use of <?php ... ?> tags.
Exercise
• Write a simple PHP script that defines two variables ($name and $age) and prints a sentence using them.
