PHP String Exercises: Get the first word of a sentence

Sample Solution:

PHP Code:

<?php
$x = '000547023.24';
// Define the original string.

$str1 = ltrim($x, '0');
// Remove leading zeros from the string.

echo $str1."\n";
// Output the modified string.
?>

Output:

547023.24

Explanation:

The above PHP code snippet takes the string '000547023.24' and removes any leading zeros from it using the "ltrim()" function. The "ltrim()" function trims characters from the left side of a string. Here, it trims leading zeros from the string '000547023.24', resulting in the string '547023.24'. Finally, it echoes out the modified string.
