php之导入导出csv文件

一、导入csv文件

1、创建导入页面

<!DOCTYPE html>
<html lang="zh-CN">
<meta charset="UTF-8">
<head><title>文件提交表单</title>
</head>
<body>
<form action="test5.php" method="post" enctype="multipart/form-data"><label for="file">选择文件:</label><input type="file" name="file" id="file"><input type="submit" name="submit" value="导入">
</form>
</body>
</html>

2、导入后端处理test5.php

<?php
/*** $filename 文件* $lineOne 是否显示标题
*/
function parseFile($filename,$lineOne=false) {if (!$filename) {die("未选择文件");}$file = fopen($filename, 'r');$arr = [];$i=0;while ($line = fgets($file)) {$i++;if($i==1&&!$lineOne){continue;}$line = rtrim($line, "\n\r\0");$encoding = mb_detect_encoding($line, ['utf-8', 'gbk', 'latin1', 'big5']);if ($encoding != 'utf-8') {$line = mb_convert_encoding($line, 'utf-8', $encoding);}$arr[] = explode(',', $line);}return $arr;
}
$filename = $_FILES['file']['tmp_name'];
$result = parseFile($filename);
print_r($result);

二、导出csv文件

<?php$output = fopen('php://output', 'w');
header('Content-type: application/csv;');
header('Content-Disposition: attachment; filename="测试——' . date("YmdHis", time()) . ".csv");fputcsv($output, [iconv('UTF-8', 'GB2312', "标题"),iconv('UTF-8', 'GB2312', '哈哈'),]
);fputcsv($output, [iconv('UTF-8', 'GB2312', "名称"),iconv('UTF-8', 'GB2312', "年龄"),iconv('UTF-8', 'GB2312', "生日"),]);
$data=[["name"=>'小明','age'=>'22','date'=>'1994-01-12'],["name"=>'小a','age'=>'12','date'=>'1994-01-33'],["name"=>'小b','age'=>'33','date'=>'1994-01-22'],["name"=>'小c','age'=>'21','date'=>'1994-01-22'],["name"=>'小d','age'=>'11','date'=>'1994-01-12'],["name"=>'小e','age'=>'22','date'=>'1994-01-12'],["name"=>'小e','age'=>'33','date'=>'1994-01-01'],
];foreach ($data as $value){fputcsv($output, array(iconv('UTF-8', 'GB2312', $value['name']),"\t" . $value['age'],"\t" . $value['date'],));
}
