PHP Arrays
An array stores multiple values in one variable. PHP has indexed (numbered) and associative (key-value) arrays.
Indexed Array
<?php
$marks = [88, 92, 79];
echo $marks[0]; // 88
echo count($marks); // 3
?>Associative Array
<?php
$student = ["name" => "Aman", "marks" => 88];
echo $student["name"]; // Aman
echo $student["marks"]; // 88
?>Looping with foreach
<?php
$prices = ["pen" => 10, "book" => 50];
foreach ($prices as $item => $price) {
echo "$item: $price<br>";
}
?>pen: 10
book: 50
Summary
- Indexed arrays use numbers; associative use key=>value.
- Use
foreachto loop;count()for size.
PHP Arrays
Array कई values एक variable में रखता है। PHP में indexed (numbered) और associative (key-value) arrays होते हैं।
Indexed Array
<?php
$marks = [88, 92, 79];
echo $marks[0]; // 88
echo count($marks); // 3
?>Associative Array
<?php
$student = ["name" => "Aman", "marks" => 88];
echo $student["name"]; // Aman
echo $student["marks"]; // 88
?>foreach से Loop
<?php
$prices = ["pen" => 10, "book" => 50];
foreach ($prices as $item => $price) {
echo "$item: $price<br>";
}
?>pen: 10
book: 50
सारांश

- Loop को
foreach; size कोcount()।
