PHP 函数封装,常用

PHP封装一个echo函数,  字符串前自动加"\t"; 字符串结尾自动加.PHP_EOL  制表符:

//用法 echoTab('abcdefg;', 2);
//默认一个制表符 "\t", #tab为缩进制表符数量;

function echoTab($data, $tab = 1) {
    $data = str_repeat("\t", $tab).$data.PHP_EOL;
    echo $data;
}

显示效果: 
       <table border = "1" style = "" cellspacing = "0">
            <tr style = "text-align: center; height: 40px;">
                <th style = "">统计时间</th>
                <th style = "">上期读数</th>
                <th style = "">本期读数</th>
                <th style = "">用量</th>
                <th style = "">金额</th>
                <th style = "width: 250px;">备注</th>
            </tr>
            <tr style = "text-align: center; background: #f5f5f5;">
                <td style = "">20240701</td>
                <td style = "padding: 0 40px;">40,002.0</td>
                <td style = "padding: 0 40px;">45,607.0</td>
                <td style = "padding: 0 40px;">5,605.0</td>
                <td style = "padding: 0 40px;">24,662.00</td>
                <td style = "">商业综合 : 5605 * 4.4 = 24662</td>
            </tr>
        <table>
