1、首先看下 phpize命令 所在的目录 (ps:我的目录/usr/bin/phpize)
如果没有找到的话 执行安装
yum install php53_devel (ps:请注意自己的版本)
安装完毕后。会生成phpize命令
2、去php.net下载相应版本的php源文件
咱们以php-5.3.17 为例吧,解压后,进入相应的模块下
cd ext/pcntl
#先执行phpize
/usr/bin/phpize
./configure --with-php-config=/usr/bin/php-config (ps:请正确的指定php-config的目录)
#编译、安装
make && make install
这时候出了一个错误
./configure编译正常,但make出错
error: ‘PHP_FE_END‘ undeclared here (not in a function)
解决方法:
源代码有错误,进入php-5.3.17目录
sed -i ‘s|PHP_FE_END|{NULL,NULL,NULL}|‘ ./ext/**/*.c
sed -i ‘s|ZEND_MOD_END|{NULL,NULL,NULL}|‘ ./ext/**/*.c
再重新make && make install
3、编译完毕后会生成了一个 pcntl.so的文件。在php的model目录里
编辑/etc/php.ini,加入
extension=pcntl.so
4、重启apache
service httpd restart
5、测试是否安装成功
<?php
echo pcntl_fork();
?>
输出:23165
php代码:
/**
* 导出文件
* @return string
*/
public function export()
{
$file_name = "成绩单-".date("Y-m-d H:i:s",time());
$file_suffix = "xls";
header("Content-Type: application/vnd.ms-excel");
header("Content-Disposition: attachment; filename=$file_name.$file_suffix");
//根据业务,自己进行模板赋值。
$this->display();
}
HTML代码:
<html xmlns:o="urn:schemas-microsoft-com:office:office"
xmlns:x="urn:schemas-microsoft-com:office:excel"

我们再来看一个更方便的组件
在这里需要用到PEAR的两个软件包 Spreadsheet Excel Writer 和 OLE,如果没有可以分别从 http://pear.php.net/package/Spreadsheet_Excel_Writer/ 和 http://pear.php.net/package/OLE/ 下载,解压放在PEAR目录下。
全部代码如下:
<?php
include ‘Writer.php‘;
/* *** 准备导出的数据 *** */
$head = ‘One Week Schedule‘;
$data = array(‘Monday‘ => array( array(‘time‘ => ‘09:00‘, ‘event‘ => ‘公司例会例会‘), array(‘time‘ => ‘14:00‘, ‘event‘ => ‘部门例会‘) ),
‘Tuesday‘ => array( array(‘time‘ => ‘09:30‘, ‘event‘ => ‘和 Mr. Stinsen 早餐‘)),
‘Wednesday‘ => array(array(‘time‘ => ‘12:10‘, ‘event‘ => ‘市场中阶报告‘), array(‘time‘ => ‘15:30‘, ‘event‘ => ‘市场部战略部署会议‘) ),
‘Thursday‘ => array( array(‘time‘ => ‘‘, ‘event‘ => ‘‘)),
‘Friday‘ => array( array(‘time‘ => ‘16:00‘, ‘event‘ => ‘WoC Stock 研讨会‘), array(‘time‘ => ‘17:00‘, ‘event‘ => ‘飞往华尔街‘), array(‘time‘ => ‘21:00‘, ‘event‘ => ‘会见克林顿‘))
);
/* *** *** */
$workbook = new Spreadsheet_Excel_Writer();
$filename = date(‘YmdHis‘).‘.xls‘;//csv
$workbook->send($filename); // 发送 Excel 文件名供下载
$workbook->setVersion( 8 );
$sheet = &$workbook->addWorksheet("Sheet1"); // 创建工作表
$sheet->setInputEncoding(‘utf-8‘); // 字符集
$headFormat = &$workbook->addFormat(array(‘Size‘ => 14, ‘Align‘ => ‘center‘,‘Color‘ => ‘white‘, ‘FgColor‘ => ‘brown‘, ‘Bold‘=>‘1‘, ‘Border‘ => ‘1‘));//定义格式
$dayFormat = &$workbook->addFormat(array(‘Size‘ => 12, ‘Align‘ => ‘center‘, ‘VAlign‘ => ‘vcenter‘, ‘FgColor‘ => ‘green‘, ‘Color‘ => ‘white‘, ‘Border‘ => ‘1‘));//定义格式
$dataFormat = &$workbook->addFormat(array(‘Size‘ => 10, ‘Align‘ => ‘left‘, ‘Border‘ => ‘1‘, ‘Color‘ => ‘black‘, ‘FgColor‘=> ‘cyan‘));//定义格式
$sheet->setColumn(0, 0, 20); // 设置宽度
$sheet->setColumn(1, 1, 15); // 设置宽度
$sheet->setColumn(2, 2, 30); // 设置宽度
$r = 0;
$sheet->write(0, $r, $head, $headFormat); // 表格标题
$sheet->mergeCells(0, 0, 0, 2); // 跨列显示
$r++; // 数据从第2行开始
foreach ($data as $day => $events){
$c = 0;
$sheet->write($r, $c, $day, $dayFormat);
if (!$events){
// 当天没有计划
$r++;
} else {
$startRow = $r;
foreach ($events as $e){
$c = 1;
$sheet->write($r, $c++, $e[‘time‘], $dataFormat); // 工作表写入数据
$sheet->write($r, $c++, $e[‘event‘], $dataFormat); // 工作表写入数据
$r++;
}
// 合并 $day 单元格
$sheet->mergeCells($startRow, 0, $r - 1, 0);
}
}
$workbook->close(); // 完成下载
?>
