PHP Indexed Arrays
An indexed array in PHP is an array that uses numbers as its keys. An array can be created by enclosing a comma-separated list of values in square brackets [], or by using the array function.
Usage
Here's an example of creating an array using both methods:
// Bracketed array
$fruits = ['apple', 'banana', 'orange'];
// Using the array function
$fruits = array('apple', 'banana', 'orange');
Looping through an indexed array
To loop through an indexed array, you can use a for loop. Here's an example of how to loop through the $fruits array and print out each value:
for ($i = 0; $i < count($fruits); $i++) {
echo $fruits[$i] . "\n";
}
Alternatively, you can use a foreach loop, which is more concise and easier to read. Here's how to do it:
foreach ($fruits as $fruit) {
echo $fruit . "\n";
}
This will output:
apple
banana
orange
