PHP 数组的添加和读取

在实际的开发中，会经常使用数组的添加和读取。这里把经常使用的操作记下来，以备以后查阅。

<?php
//一维数值数组
$list = array('wang','god');
$list[] ='biaobiao';
$list[] = 'chaofan';
foreach($list as $v){
    echo $v."<br />";
}

//一维关联数组
$list1 = array(
    'name' => 'god',
    'info' => 'XXXXX',
    'number' => 123213
    );
$list1['address'] = 'Beijing';
foreach($list1 as $key => $value){
    echo $key . "=>" . $value."<br />";
}


//二位数值数组
$list = array(
    array(1,4,12,3),
    array(2,5,6,10),
    array(3,7,9,8)
);
foreach($list as $value){
    foreach($value as $v){
        echo $v ." ";
    }
    echo "<br />";
}

//二维数组关联数组
$lists = array();
$list0 = array(
    'name' => 'god',
    'info' => 'XXXXX',
    'number' => 123213
);
$lists[] = $list0;
$list1 = array(
    'name' => 'chaofan',
    'info' => 'SSSSSS',
    'number' => 41123
);
$lists[] = $list1;
$list2 = array(
    'name' => 'biaobiao',
    'info' => '#######',
    'number' => 56732
);
$lists[] = $list2;

foreach($lists as $key => $value){
    echo "name:".$lists[$key]['name']." info:".$lists[$key]['info']." number:".$lists[$key]['number']."<br />";
}

foreach($lists as $key => $value){
    $lists[$key]['nick'] =  $lists[$key]['name']." host";
}
?>
