我试图将csv文件读入数组。这是我到目前为止将csv读入数组所得到的:
$i = 0;
while ($i < $fileLines) {
$userDB=Array(
($i) => Array
(
(title) => $harry[$i][0],
(subtitle) => $harry[$i][1],
(series) => $harry[$i][2],
(author) => $harry[$i][3],
(author2) => $harry[$i][4],
(author3) => $harry[$i][5],
(category) => $harry[$i][6],
(subjects) => $harry[$i][7],
(callnumber) => $harry[$i][8],
(isbn) => $harry[$i][9],
(publisher) => $harry[$i][10],
(keywords) => $harry[$i][11],
(option1) => $harry[$i][12],
(option2) => $harry[$i][13],
(option3) => $harry[$i][14],
(option4) => $harry[$i][15],
(option5) => $harry[$i][16],
(option6) => $harry[$i][17]
) // end child array
); // end parent array
$i++;
} // end while
以下是我使用的CVS示例:
"Algebra and Trigonometry with Analytic Geometry, Classic Edition",,,"Swokowski, Earl","Cole, Jeffery A.",,Cengage Learning,,,495559717,,,,," ALGEBRA AND TRIGONOMETRY WITH ANALYTIC GEOMETRY, CLASSIC EDITION 12 SWOKOWSKI, EARL COLE, JEFFERY A. CENGAGE LEARNING 2009-01-28 912 500 0495559717 "
All My Friends Are Dead,,,"Monsen, Avery","John, Jory",,Chronicle Books,,,811874559,,,,," ALL MY FRIENDS ARE DEAD MONSEN, AVERY JOHN, JORY CHRONICLE BOOKS 2010-06-30 96 500 0811874559 "
All My Friends Are Still Dead,,,"John, Jory","Monsen, Avery",,Chronicle Books,,,1452106967,,,,," ALL MY FRIENDS ARE STILL DEAD 3.2.2012 JOHN, JORY MONSEN, AVERY CHRONICLE BOOKS 2012-03-07 108 500 1452106967 "
当我尝试循环写入数组时,我的问题出现了。如果我注释掉while循环,那么我正确读取了CSV中的第一项。但是,当我尝试使用while循环时,我不会将任何数据写入数组。我错过了什么/完全错了?
我还没有包含我的所有代码,因为我不想淹死所有人,但如果有帮助我可以加入更多代码。

您必须在while循环之前声明$userDB
:
$i = 0;
$userDB = array();
while ($i < $fileLines) {
$userDB[] => Array
(
(title) => $harry[$i][0],
(subtitle) => $harry[$i][1],
(series) => $harry[$i][2],
(author) => $harry[$i][3],
(author2) => $harry[$i][4],
(author3) => $harry[$i][5],
(category) => $harry[$i][6],
(subjects) => $harry[$i][7],
(callnumber) => $harry[$i][8],
(isbn) => $harry[$i][9],
(publisher) => $harry[$i][10],
(keywords) => $harry[$i][11],
(option1) => $harry[$i][12],
(option2) => $harry[$i][13],
(option3) => $harry[$i][14],
(option4) => $harry[$i][15],
(option5) => $harry[$i][16],
(option6) => $harry[$i][17]
) // end child array
); // end parent array
$i++;
} // end while
顺便说一下,为什么不直接使用fgetcsv或str_getcsv php函数?
$userDB = str_getcsv($fileLines);
答案 1 :(得分:0)
我使用了这种方法:
$formattedArr = array(); // create array
$filename = "sample.csv"; // point to CSV file
if (($handle = fopen($filename, "r")) !== FALSE) {
$key = 0; // set array key.
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
$count = count($data); //get total keys in row
for ($i=0; $i < $count; $i++) { //insert data to our array
$formattedArr[$key][$i] = $data[$i];
} // end for
$key++;
} // end while
fclose($handle); //close file handle
} // end if
它运行CSV并将每个项目添加到一个位置(例如$ formattedArr [0] [0] =“代数和三角学与解析几何,经典版”。感谢大家的意见,建议和答案。
