#30 Fungsi Array dan Contoh Penggunaan Data Array pada PHP yang Wajib Kamu Tau

Berikut Fungsi / metode array php yang wajib diketahui beserta penggunaan data Array pada pemrograman PHP

Pada sesi ini, kita akan belajar pemrograman PHP dan mengenal fungsi-fungsi atau metode Array yang bisa digunakan dalam aplikasi PHP. Tentu dengan menggunakan array akan mempermudah kita dalam membuat kelompok data, dan akan menghemat penulisan code program serta penggunaan variabel-variable.

Nah, mungkin masih banyak yang belum tau betapa dahsyatnya fungsi-fungsi Array yang sudah disediakan oleh PHP sendiri yang bisa digunakan untuk mempermudah dalam mengolah data-data yang kompleks, berikut ini metode Array pada PHP lengkap dengan contoh penggunaannya.

is_array()

<?php
  // Array
  $varr1 = ['kodeajaib','sectorcode'];
  // Variable
  $varr2 = 'kodeajaib.com';
  // cek apakah varr1 array atau tidak
  if (is_array($varr1)) {
    echo "variable varr1 adalah Array";
  } else {
    echo "Variable varr1 bukan Array";
  }
  echo "<br>";
  // cek apakah varr2 array atau tidak
  if (is_array($varr2)) {
    echo "variable varr2 adalah Array";
  } else {
    echo "Variable varr2 bukan Array";
  }
?>

explode()


<?php
  // contoh pertama
  $nama  = "butet buyung ucok keneng upik opung";
  $data = explode(" ", $nama);

  foreach ($data as $key => $value) {
    echo $value;
    echo "<br>";
  }
  // butet
  // buyung
  // ucok
  // keneng
  // upik
  // opung

  // contoh dua
  $root = "kodeajaib:sectorcode:1023:1000::/home/foo:/bin/sh";
  list($user, $pass, $uid, $gid, $gecos, $home, $shell) = explode(":", $root);
  echo $user;
  echo $pass;

  // kodeajaib
  //sectorcode
?>

implode()

<?php
  $myArr = ['kucing','kambing','sapi'];
  $data = implode(",", $myArr);
  echo $data;
  // kucing,kambing,sapi
?>

preg_split()

<?php
  $varr = preg_split("/[s,]+/", "Selamat datang di kodeajaib.com");
  foreach ($varr as $key => $value) {
    echo $value;
    echo "<br>";
  }
  //selamat
  //datang
  //di
  //kodeajaib.com
?>

str_split()

<?php
  $myStr = "Selamat datang di KodeAjaib.com";
  $arr1 = str_split($myStr);
  $arr2 = str_split($myStr, 3);

  echo "<pre>";
  print_r($arr1);
  echo "<br>";
  print_r($arr2);
  echo "</pre>";

  // Array
