এই lesson আমরা PHP এর Variable, String, Constant, Array, Operators, For loop, While Loop, Do While Loop, For Each Loop নিয়ে আলোচনা করব

 

Source Code:

 

Array:

$a = [1, 2, 5, 3, 9];

$b = [
	'b' 	=> 78,
	'g' 	=> 21,
	'k' => 57
];

$c = [
	[1, 2, 3],
	[4, 5, 6]
];
asort($b);
print_r($b);

 

Conditional Statement IF:

$a = 12;

if ($a == 6) {
	echo "Welcome";
} else if ($a == 5) {
	echo "Welcome to dhaka";
} else {
	echo 'Go home';
}

 

Switch Statement:

$a = 12;
switch ($a) {
	case 6:
		echo "Welcome";
		break;
	case 5:
		echo "Welcome to dhaka";
		break;
	default:
		echo "Go home";
		break;
}

 

Loop:

for( $i = 1; $i <10; $i++ ) {
	echo "$i ";
}
echo "<br/> ";

$j = 1;
while($j < 10) {
	echo "$j ";
	$j++;
}

echo "<br/> ";
$k = 1;
do {
	echo "$k ";
	$k++;
} while( $k < 10 );

 

Foreach loop:

items = [ 2, 45, 12, 23, 12, 40 ];

foreach($items as $key => $item) {
	echo "($key, $item) ";
}
