Adding an Element to the Beginning of an Array

 
<?php
  $prices = array(5.95, 10.75, 11.25);
  
  printf("<p>%s</p>\n", implode(", ", $prices));
  
  array_unshift($prices, 10.85);
  printf("<p>%s</p>\n", implode(", ", $prices));
  
  array_unshift($prices, 3.35, 17.95);
  printf("<p>%s</p>\n", implode(", ", $prices));
?>

Adding an Element to the Beginning of an Array: int array_unshift(array $arr, mixed $val[, mixed $val2[, ...]])

 
<?php 
$prices = array(5.95, 10.75, 11.25); 
printf("<p>%s</p>\n", implode(", ", $prices)); 
array_unshift($prices, 10.85); 
printf("<p>%s</p>\n", implode(", ", $prices)); 

array_unshift($prices, 3.35, 17.95); 
printf("<p>%s</p>\n", implode(", ", $prices)); 
?>

array_unshift( ) function pushes value onto the start of the array

 
int array_unshift ( array &arr, mixed var [, mixed ...] )
<?
    $firstname = "Johnny";
    $names = array("Timmy", "Bobby", "Sam", "Tammy", "Joe");
    array_unshift($names, $firstname);
?>

array_unshift() function shifts the array to the right.

 
//Its syntax is: int array_unshift(array array, mixed var1 [, mixed var2. . .])
//You can append one or several values simultaneously.
<?
    $languages = array ("French", "Italian");
    array_unshift ($languages, "Russian", "Chinese");
    print_r($languages);
?>
