通用PHPExcel导出excel函数代码
公用函数:/**
* 数据表导出excel
*
* @author rainfer
*
* @param string $table,不含前缀表名,必须
* @param string $file,保存的excel文件名,默认表名为文件名
* @param string $fields,需要导出的字段名,默认全部,以半角逗号隔开
* @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
* @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;"
* 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)
* order:排序方式，如：post_date desc
* where:查询条件，字符串形式，和sql语句一样

}用到的2个函数:/**
* 生成参数列表,以数组形式返回
* @author rainfer
*/
function param2array($tag = ''){
$param = array();
$array = explode(';',$tag);
foreach ($array as $v){
$v=trim($v);
if(!empty($v)){
list($key,$val) = explode(':',$v);
$param[trim($key)] = trim($val);
}
}
return $param;
}
/**
* 数字到字母列
* @author rainfer
*/
function num2alpha($intNum, $isLower = false)
{
$num26 = base_convert($intNum, 10, 26);
$addcode = $isLower ? 49 : 17;
$result = '';
for ($i = 0; $i $code = ord($num26{$i});
if ($code $result .= chr($code + $addcode);
} else {
$result .= chr($code + $addcode - 39);
}
}
return $result;
