How to Loop Through an Array in PHP

Iterating through an array in programming is a basic task that can be used for a variety of purposes. PHP arrays can store data of various types, such as integers, strings, and objects. In order to access the data stored in an array, we need to loop through the array. 

In PHP, there are two ways to loop through an array. The first way is to use a for loop, and the second way is to use a foreach loop.

$explanations = [
    'Array is a data structure that allows you to store data in an indexed fashion.',
    'PHP arrays are a powerful way to store and manipulate data and are a key part of many web applications.',
    'An array is a type of data structure that stores elements of the same type in a contiguous block of memory.',
    'The PHP array is a data structure that allows you to store data in a organized way. It is a powerful tool that can help you keep your data organized and easy to manipulate.',
];

foreach($explanations as $key => $ex) {
	echo $key.': '.$ex;
}
for ($i = 0; $i < count($explanations); $i++) {
    echo $explanations[$i];
}
