PHP offers a variety of built-in functions to modify strings.
Convert to Upper Case
The strtoupper() function converts a string to upper case.
Example:
$brand = "Yamaha is great!"; echo strtoupper($brand);
Convert to Lower Case
The strtolower() function converts a string to lower case.
Example:
$brand = "Ducati is amazing!"; echo strtolower($brand);
Replace String Content
The str_replace() function replaces specific characters in a string with other characters.
Example:
Replace “Ferrari” with “Lamborghini”:
$car = "I love Ferrari!";
echo str_replace("Ferrari", "Lamborghini", $car);Reverse a String
The strrev() function reverses the characters in a string.
Example:
$brand = "Harley Davidson!"; echo strrev($brand);
Remove Whitespace
Whitespace refers to any spaces before and after the actual text. The trim() function removes these spaces.
Example:
$greeting = " Hello Riders! "; echo trim($greeting);
Convert String to Array
The explode() function splits a string into an array based on a specified separator.
Example:
Split the string into an array using space as a separator:
$text = "Ride safe always!";
$words = explode(" ", $text);
// Use the print_r() function to display the result:
print_r($words);
/*
Result:
Array ( [0] => Ride [1] => safe [2] => always! )
*/
