配列は変数に[ ]を付ける、echoとprintなど．．．

配列は$var[]のように書けばいい。echoとprintの書き方にも注意。

source

<?php
$var[] = "data1";
$var[] = "data2";
$var[] = "data3";

echo "$var[0] <br>\n";
echo "$var[1] <br>\n";
echo "$var[2] <br>\n";

echo("$var[0] <br>\n");
echo("$var[1] <br>\n");
echo("$var[2] <br>\n");

print "$var[0] <br>\n";
print "$var[1] <br>\n";
print "$var[2] <br>\n";

print("$var[0] <br>\n");
print("$var[1] <br>\n");
print("$var[2] <br>\n");
?>
