Question

我有一个CSV文件，下面的代码用于将CSV的内容放入多维数组中。

<?php

$val = $_GET['articleid'];
//URL Pass STring

$arrCSV = array();
// Open the CSV
if (($handle = fopen("../articles/artlist.csv", "r")) !==FALSE) {                         
// Set the parent array key to 0
$key = 0;
// While there is data available loop through unlimited times (0) using separator (,)
while (($data = fgetcsv($handle, 0, ",")) !==FALSE) {
   // Count the total keys in each row
   $c = count($data);
   //Populate the array
   for ($x=0;$x<$c;$x++) {
   $arrCSV[$key][$x] = $data[$x];
   }
   $key++;
} // end while
// Close the CSV file
fclose($handle);
} // end if

?>

我的第一部分是输出整个数组。

我认为以下代码是错误的:(

  <?php       
        for ( $row = 1; $row <$arrCSV; $row++ )
            {
        echo ''.$arrCSV[$row]['6'].'';  
            }
    ?>

然后我只想输出其中一列[*] [6]。

在我尝试其余的事情之前，我想我应该先到这里。

任何指导都会有所帮助。

我正在努力学习，到目前为止，我已经走到了这一步。

谢谢

Answer 1

这不起作用吗？：

<?php
$val = $_GET['articleid'];
//URL Pass STring

$arrCSV = array();
// Open the CSV
if (($handle = fopen("../articles/artlist.csv", "r")) !==FALSE) {                         

// While there is data available loop through unlimited times (0) using separator (,)
while (($data = fgetcsv($handle, 0, ",")) !==FALSE) {
   $arrCSV[] = $data;
} // end while
// Close the CSV file
fclose($handle);
} // end if

?>

我使用此功能将CSV转换为数组

function csv2array($string, $separatorChar = ',', $enclosureChar = '"', $newlineChar = "\n") 
{
    $array = array();
    $size = strlen($string);
    $columnIndex = 0;
    $rowIndex = 0;
    $fieldValue = "";
    $isEnclosured = False;

    for($i=0; $i<$size;$i++) 
    {
        $char = $string{$i};
        $addChar = "";

        if($isEnclosured) 
        {
            if($char == $enclosureChar) 
            {
                if($i+1<$size && $string{$i+1} == $enclosureChar)
                {
                    $addChar = $char;
                    $i++; 
                }
                else
                {
                    $isEnclosured = false;
                }
            }
            else 
            {
                $addChar=$char;
            }
        }
        else 
        {
            if($char==$enclosureChar) 
            {
                $isEnclosured = true;
            }
            else 
            {
                if($char==$separatorChar) 
                {
                    $array[$rowIndex][$columnIndex] = $fieldValue;
                    $fieldValue = "";
                    $columnIndex++;
                }
                elseif($char==$newlineChar) 
                {
                    $array[$rowIndex][$columnIndex] = $fieldValue;
                    $fieldValue="";
                    $columnIndex=0;
                    $rowIndex++;
                }
                else 
                {
                    $addChar=$char;
                }
            }
        }

        if($addChar != "")
        {
            $fieldValue.=$addChar;
        }
    }

    if($fieldValue) 
    {
        $array[$rowIndex][$columnIndex] = $fieldValue;
    }

    return $array;
}

您可以像这样使用它：

<?php

$handle = fopen("../articles/artlist.csv", "r");
$arr = csv2array($handle);

print_r($arr);

?>

这是解决方案

要访问CSV：

 <?php

$val = $_GET['articleid'];
//URL Pass STring

$arrCSV = array();
// Open the CSV
if (($handle = fopen("../articles/artlist.csv", "r")) !==FALSE) {                         
// Set the parent array key to 0
$key = 0;
// While there is data available loop through unlimited times (0) using separator (,)
while (($data = fgetcsv($handle, 0, ",")) !==FALSE) {
   // Count the total keys in each row
   $c = count($data);
   //Populate the array
   for ($x=0;$x<$c;$x++) {
   $arrCSV[$key][$x] = $data[$x];
   }
   $key++;
} // end while
// Close the CSV file
fclose($handle);
} // end if

?>

要在CSV中显示整个列：

 <?php       
        for ( $row = 1; $row <$arrCSV; $row++ )
            {
        echo ''.$arrCSV[$row]['6'].'';  
            }
    ?>

从CSV-PHP输出所有多维数组，数组数据
