通用PHPExcel导出excel函数代码
公用函数:/**<br>
* 数据表导出excel<br>
*<br>
* @author rainfer <br>
*<br>
* @param string $table,不含前缀表名,必须<br>
* @param string $file,保存的excel文件名,默认表名为文件名<br>
* @param string $fields,需要导出的字段名,默认全部,以半角逗号隔开<br>
* @param string $field_titles,需要导出的字段标题,需与$field一一对应,为空则表示直接以字段名为标题,以半角逗号隔开<br>
* @param stting $tag,筛选条件 以字符串方式传入,例："limit:0,8;order:post_date desc,listorder desc;where:id>0;"<br>
* limit:数据条数,可以指定从第几条开始,如3,8(表示共调用8条,从第3条开始)<br>
* order:排序方式，如：post_date desc<br>
* where:查询条件，字符串形式，和sql语句一样<br>

}用到的2个函数:/**<br>

*/<br>
function param2array($tag = ''){<br>
$param = array();<br>
$array = explode(';',$tag);<br>
foreach ($array as $v){<br>
$v=trim($v);<br>
if(!empty($v)){<br>
list($key,$val) = explode(':',$v);<br>
$param[trim($key)] = trim($val);<br>
}<br>
}<br>
return $param;<br>
}<br>
/**<br>
* 数字到字母列<br>

*/<br>
function num2alpha($intNum, $isLower = false)<br>
{<br>
$num26 = base_convert($intNum, 10, 26);<br>
$addcode = $isLower ? 49 : 17;<br>
$result = '';<br>
for ($i = 0; $i
$code = ord($num26{$i});<br>
if ($code
$result .= chr($code + $addcode);<br>
} else {<br>
$result .= chr($code + $addcode - 39);<br>
}<br>
}<br>
return $result;<br>
