array -- 配列を生成する

説明

array array(...);

パラメータの配列を返します。パラメータには、 =>演算子によりインデックスを指定することもできます。

注意: array()は、実際にはリテラル配列を表現するための 言語構成要素であり、通常の関数ではありません。

以下の例では、2 次元配列の生成方法、連想配列のキーの指定方法、 および通常の配列において添字番号をスキップし、それに続く 要素にアクセスする方法についてご紹介しています。

例 1. array()の例


$fruits = array (
    "fruits"  => array("a"=>"orange", "b"=>"banana", "c"=>"apple"),
    "numbers" => array(1, 2, 3, 4, 5, 6),
    "holes"   => array("first", 5 => "second", "third")
);

list()も参照下さい。

I wonder how associative array is implemented. I guess that it is based on hash function reference technique. It will be better in using this array facility if this manual notes the associative array implementation mechanism since execution speed is highly dependant to it.

Every array has an "internal pointer". When you create an array, the internal pointer is automatically set to point at the first member. You can print the current location of the pointer:

<pre>
$bob= current($myarrayname);
echo "$bob";
</pre>

You can advance the pointer to the next spot using next($myarrayname).

To see a particular member of an array, set a $variable= $myarrayname[2] where "2" is the number of the member you want to use.

When assigning members to an array, the members are numbered beginning with 0, rather than 1.

Cuando se crea un vector no es necesario agregar los numeros de indice.
ejemplo:
$mi_vector=array ("DOMINGO",0000,0000);

Displaying all data in a two-dimensional array is actually pretty simple:
<PRE>
<?
$users = array(
"djuan" => array(
"firstname" => "Don",
"lastname" => "Juan",
"age" => "102",
"weight" => "100"
),

"jordan23" => array(
"firstname" => "Michael",
"lastname" => "Jordan",
"age" => "36",
"weight" => "225"
)
);

/* Now print out the contents of the array. */

while ( list($username, $subarray) = each($users) ) {
echo "Username: $username: ";
echo "<ul>";

while ( list($key, $val) = each($subarray) ) {
echo "<li>$key : $val\n";
}

echo "</ul>";
}

?>

This will print out (assuming you're using a browser and not your shell):

Username: djuan:

firstname : Don
lastname : Juan
age : 102
weight : 100

Username: jordan23:

firstname : Michael
lastname : Jordan
age : 36
weight : 225
</PRE>

I use this to completely display the content of an array:
<pre>
function print_array($array) {
if(gettype($array)=="array") {
echo "<ul>";
while (list($index, $subarray) = each($array) ) {
echo "<li>$index <code>=&gt;</code> ";
print_array($subarray);
echo "</li>";
}
echo "</ul>";
} else echo $array;
}
</pre>

Arrays of objects is supposed to sneak into 4.0 final, and may already be in the betas.

If you want to create an array of a set size and you have PHP4, use array_pad(array(), $SIZE, $INITIAL_VALUE); This can be handy if you wish to initialize a bunch of variables at once:

list($Var1, $Var2, etc) = array_pad(array(), $NUMBER_OF_VARS, $INITIAL_VALUE);

the following code will allow you to generate an array on the fly,

$record = array ("item1" => "whatever");
$record["item2"]="something";

I think that the way they explain the use of arrays is very bad. A much easier way to think about it is to compare with standard arrays in C. You can declare an array like: $array = array() and then just add items to it using syntax: $array[1] = 'poo'; for two dim arrays, use $array = array(array()), and reference using $array[x][x]. Much simpler...

To pass an array to another script, try serializing the array, then urlencoding the serialized value. Pass the array to the new script, then unserialize it to access it's contents. Check out Serialize and Unserialize for more info.

An array of objects in version 3.

var userlist;
$user = new User();
$user->fillFromRow($row);
userlist[$ctr] = $user;
$firstuser = (Object) userlist[0];
