String & Fungsi String

String Basics

<?php
$text = "Halo, PHP!";

echo strlen($text);           // 10
echo strtoupper($text);       // HALO, PHP!
echo strtolower($text);       // halo, php!
echo ucfirst($text);          // Halo, php!
?>

String Manipulation

<?php
$text = "Halo, Dunia";

echo strpos($text, "Dunia");        // 6
echo str_replace("Dunia", "PHP", $text); // Halo, PHP
echo explode(",", $text);          // Array
echo substr($text, 0, 4);          // Halo
?>

String Trimming

<?php
$text = "  Halo, PHP!  ";

echo trim($text);   // Halo, PHP! (hapus spasi di awal dan akhir)
echo ltrim($text);  // Halo, PHP!  (hapus spasi di awal)
echo rtrim($text);  //   Halo, PHP! (hapus spasi di akhir)
?>
