从php表导出为.csv，而不创建新的sql表
对于一个项目，我必须将我制作的报告导出到一个文件位置。它必须是.csv文件格式，并且需要包含标题从php表导出为.csv，而不创建新的sql表,php,html,sql,postgresql,export-to-csv,Php,Html,Sql,Postgresql,Export To Csv,对于一个项目，我必须将我制作的报告导出到一个文件位置。它必须是.csv文件格式，并且需要包含标题 <html> <?php $profiles = new CGenRs("SELECT * from adapt_profile ", $database); $profiles->first(); $users = new CGenRs("SELECT * from authuser where userno in (select user_

这可能是一个好的开始（使用Javascript/JQuery），改编自演示代码中引用的源代码：
JSFiddle演示注意：提琴版可能无法在IE中使用-请尝试FF或Chrome
下面是我如何使用javascript将表数据提取到字符串中的：
var $rows = $table.find('tr:has(td)'),
// Temporary delimiter characters to avoid accidentally splitting the actual contents
tmpColDelim = String.fromCharCode(11), // vertical tab character
tmpRowDelim = String.fromCharCode(0), // null character
// actual delimiter characters for CSV format
colDelim = ',',
rowDelim = '\r\n',
// Grab text from table into CSV formatted string
csv = $rows.map(function(i, row) {
var $row = $(row),
$cols = $row.find('td');
return $cols.map(function(j, col) {
var $col = $(col),
text = '="' + $col.text() + '"'; // to make dates interpret literally in excel
return text.replace(/"/g, '"'); // escape double quotes
}).get().join(tmpColDelim);
}).get().join(tmpRowDelim)
.split(tmpRowDelim).join(rowDelim)
.split(tmpColDelim).join(colDelim);
IE的行为与其他浏览器不同：
// IE9+ support - using iframe to set up file
// https://github.com/angular-ui/ui-grid/issues/2312#issuecomment-70348120
// note: if using IE10+, consider ieblob: https://github.com/mholt/PapaParse/issues/175#issuecomment-75597039
if (msieversion()) {
var frame = document.createElement('iframe');
document.body.appendChild(frame);
frame.contentWindow.document.open("text/html", "replace");
frame.contentWindow.document.write('sep=,\r\n' + csv);
frame.contentWindow.document.close();
frame.contentWindow.focus();
frame.contentWindow.document.execCommand('SaveAs', true, fileName);
document.body.removeChild(frame);
return true;
} else {
var uri = 'data:application/csv;charset=utf-8,' + encodeURIComponent(csv);
$(this).attr({
'download': fileName,
'href': uri,
'target': '_blank'
});
}
这些只是片段，请参阅完整的JSFIDLE以了解详细信息
我修改了注释掉的代码引用来处理我的表-我认为表到字符串位会对您有所帮助，如果您想在客户端执行任何操作的话
