PHP数组用法

<?php

class Foo {
    var $foo;
    var $bar;
    var $fruits = array(‘strawberry‘ => ‘red‘, ‘banana‘ => ‘yellow‘);
    function foo(){
        $this->foo = ‘Foo‘;
        $this->bar = array(‘Bar1‘,‘Bar2‘,‘Bar3‘);
    }

}

<?php
$foo = new Foo();
$foo->bar[4] = "Admin";
echo $foo->bar[4];
echo count($foo->bar);
?>

<?php
    $foo = new Foo();
    $foo->fruits["Name"]="Admin";
    echo $foo->fruits["Name"];
    foreach($$foo->fruits as $x=>$x_value) {
        echo "Key=" . $x . ", Value=" . $x_value;
        echo "<br>";
    }
?>
