如何将csv文件的每一行存储到php中的数组中

我不理解每个数组中的每一行。

使用fgetcsv()函数读取CSV文件php.

<?php
$row = 1;
if (($handle = fopen("test.csv", "r")) !== FALSE) {
    while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
        $num = count($data);
        echo "<p> $num fields in line $row: <br /></p>'n";
        $row++;
        for ($c=0; $c < $num; $c++) {
            echo $data[$c] . "<br />'n";
        }
    }
    fclose($handle);
}
?>

或如果你想将它们存储在数组中，你可以使用

$data = array();
if (($handle = fopen("test.csv", "r")) !== FALSE) {
    while(($row = fgetcsv($handle, 1000, ",")) !== FALSE) {
        $data[] = $row;
    }
}

假设CSV是一个文件(如果不是，让CSV匹配$csv，它本质上是由单独的行分解的文件)，这里有一个非常简单的方法:

$csv = file('mycsv.csv'); $result = array();
//iterate the lines
foreach ($csv as $line)
  // I'd recommend  more robust "csv-following" method though (fgetcsv maybe)
  $result[] = explode(',',$result); 
//show the results
print_r($result);

虽然fgetcsv可能是一个更安全的赌注(正如其他人提到的)(参见文档)。

进一步扩展您的评论:

//iterate the lines
foreach ($csv as $line)
  // I'd recommend  more robust "csv-following" method though (fgetcsv maybe)
  $result[] = explode(',',$result); 

可以成为:

//iterate the lines
foreach ($csv as $line)
  // combine the current results with the new results
  $result = array_marge($result,$line);

或者，如果顺序很重要:

//iterate the lines
foreach ($csv as $line)
  // add each result on to the end of the result array
  foreach($line as $val)
    // add each value
    $result[] = $val;

您可以使用fgetcsv():

$data = array();
if (($handle = fopen("test.csv", "r")) !== FALSE) {
    while(($row = fgetcsv($handle, 1000, ",")) !== FALSE) {
        $data[] = $row;
    }
}
