What are some best practices for handling arrays and string manipulation in PHP?

When handling arrays and string manipulation in PHP, it is important to use built-in functions and methods to efficiently manipulate data. This can include functions like array_push(), array_pop(), implode(), explode(), strlen(), substr(), and more. By utilizing these functions, you can avoid reinventing the wheel and write cleaner, more concise code. 

// Example of handling arrays and string manipulation in PHP

// Creating an array and adding elements using array_push()
$fruits = ['apple', 'banana', 'orange'];
array_push($fruits, 'grape');

// Removing the last element from the array using array_pop()
$lastFruit = array_pop($fruits);

// Combining array elements into a string using implode()
$fruitString = implode(', ', $fruits);

// Splitting a string into an array using explode()
$colors = 'red, green, blue';
$colorArray = explode(', ', $colors);

// Getting the length of a string using strlen()
$word = 'Hello';
$length = strlen($word);

// Extracting a substring from a string using substr()
$subString = substr($word, 0, 3);
