How can PHP beginners effectively learn and implement string manipulation techniques, such as splitting strings into smaller parts?

To effectively learn and implement string manipulation techniques in PHP, beginners can start by understanding the basic functions like `explode()` for splitting strings into smaller parts. They can practice using this function with different delimiter characters and explore other functions like `substr()` for extracting specific parts of a string. Additionally, utilizing online resources, tutorials, and practicing coding exercises can help solidify their understanding and skills in string manipulation.

// Example of splitting a string into smaller parts using explode()
$string = "Hello,World,PHP";
$parts = explode(",", $string);

foreach ($parts as $part) {
    echo $part . "<br>";
}
