Answer 1

Just use fputcsv it takes care of escaping and producing correct csv data.

<?php

$list = array (
    array('aaa', 'bbb', 'ccc', 'dddd'),
    array('123', '456', '789'),
    array('"aaa"', '"bbb"')
);

$fp = fopen('file.csv', 'w');

foreach ($list as $fields) {
    fputcsv($fp, $fields);
}

fclose($fp);
?>

Output:

aaa,bbb,ccc,dddd
123,456,789
"""aaa""","""bbb"""

Edit

You can always use a combination of tmpfile to open a file that will be automatically deleted at the end of the request, write to it and then after the report is created output its content with fread . You have to use fread since tmpfile return a resource, otherwise you can use tempnam + file_get_contents but in that case you have to open the file and to cleanup after read it by yourself.

通常的方法是用一对"包装数据，并使用""表示数据中的双引号字符。

foo,bar,"sometimes you get data containing a "","" character","23,000"

Answer 4

You can do it from a query using SELECT .. INTO OUTFILE eg

SELECT p.pNum, p.pName, a.varcharValue
FROM ds_products p   
LEFT JOIN productAttribute a ON a.id=p.pID 
WHERE a.attributeId = (select id FROM attribute where attributeName='alternateTitle')
INTO OUTFILE '/path/on/server'

If you want to add a header row:

SELECT 'A', 'B', 'C'
UNION
SELECT p.pNum, p.pName, a.varcharValue
FROM ds_products p   
LEFT JOIN productAttribute a ON a.id=p.pID 
WHERE a.attributeId = (select id FROM attribute where attributeName='alternateTitle')
INTO OUTFILE '/path/on/server'
