需要将csv或xls导入到使用CodeIgniter创建的Application中。这有什么图书馆吗？任何建议都表示赞赏。

这是一种简单的方法。我不知道人们做了什么，但我使用了这个

这是我的csv阅读器库

<?php if (!defined('BASEPATH')) exit('No direct script access allowed');

class CSVReader {

    var $fields;            /** columns names retrieved after parsing */ 
    var $separator = ';';    /** separator used to explode each line */
    var $enclosure = '"';    /** enclosure used to decorate each field */

    var $max_row_size = 4096;    /** maximum row size to be used for decoding */

    function parse_file($p_Filepath) {

        $file = fopen($p_Filepath, 'r');
        $this->fields = fgetcsv($file, $this->max_row_size, $this->separator, $this->enclosure);
        $keys_values = explode(',',$this->fields[0]);

        $content    =   array();
        $keys   =   $this->escape_string($keys_values);

        $i  =   1;
        while( ($row = fgetcsv($file, $this->max_row_size, $this->separator, $this->enclosure)) != false ) {            
            if( $row != null ) { // skip empty lines
                $values =   explode(',',$row[0]);
                if(count($keys) == count($values)){
                    $arr    =   array();
                    $new_values =   array();
                    $new_values =   $this->escape_string($values);
                    for($j=0;$j<count($keys);$j++){
                        if($keys[$j] != ""){
                            $arr[$keys[$j]] =   $new_values[$j];
                        }
                    }

                    $content[$i]=   $arr;
                    $i++;
                }
            }
        }
        fclose($file);
        return $content;
    }

    function escape_string($data){
        $result =   array();
        foreach($data as $row){
            $result[]   =   str_replace('"', '',$row);
        }
        return $result;
    }   
}
?>

和控制器方法

function readExcel()
{
        $this->load->library('csvreader');
        $result =   $this->csvreader->parse_file('Test.csv');

        $data['csvData'] =  $result;
        $this->load->view('view_csv', $data);  
}

这是观点

<table cellpadding="0" cellspacing="0" width="100%">
    <tr>
            <td width = "10%">ID</td>
            <td width = "20%">NAME</td>
            <td width = "20%">SHORT DESCRIPTION</td>
            <td width = "30%">LONG DESCRIPTION</td>
            <td width = "10%">STATUS</td>
            <td width = "10%">PARENTID</td>
    </tr>

            <?php foreach($csvData as $field){?>
                <tr>
                    <td><?php echo $field['id']?></td>
                    <td><?php echo $field['name']?></td>
                    <td><?php echo $field['shortdesc']?></td>
                    <td><?php echo $field['longdesc']?></td>
                    <td><?php echo $field['status']?></td>
                    <td><?php echo $field['parentid']?></td>
                </tr>
            <?php }?>
</table>

这是raheel shan接受的答案的改进版本 - 我编辑了他的答案，但我的编辑被拒绝，但这是一个重要的变化......

在解析每个数据行时，在逗号上使用for el in xl: print el for iel in el: print ' '*4 + str(iel) for iiel in iel: print ' '*8 + str(iiel) >>> [[0, 0], [-1, 1], [-2, 2]] [0, 0] 0 0 [-1, 1] -1 1 [-2, 2] -2 2 [[-3, 3], [-4, 4], [-5, 5]] [-3, 3] -3 3 [-4, 4] -4 4 [-5, 5] -5 是不明智的，因为这不会处理包含逗号的引用包含的字符串。爆炸将这些字符串分解为子字符串并在explode()中提供额外的数组元素，因此此检查失败：

$values

相反，PHP有一个专用的方法来处理这个问题; str_getcsv()。我已相应更新了原始答案代码。

CSV阅读器库：

if (count($keys) == count($values)) {

控制器方法：

<?php
if (!defined('BASEPATH'))
    exit('No direct script access allowed');

class CSVReader {

    var $fields;/** columns names retrieved after parsing */
    var $separator = ';';/** separator used to explode each line */
    var $enclosure = '"';/** enclosure used to decorate each field */
    var $max_row_size = 4096;/** maximum row size to be used for decoding */

    function parse_file($p_Filepath) {

        $file = fopen($p_Filepath, 'r');
        $this->fields = fgetcsv($file, $this->max_row_size, $this->separator, $this->enclosure);
        $keys = str_getcsv($this->fields[0]);

        $i = 1;
        while (($row = fgetcsv($file, $this->max_row_size, $this->separator, $this->enclosure)) != false) {
            if ($row != null) { // skip empty lines
                $values = str_getcsv($row[0]);
                if (count($keys) == count($values)) {
                    $arr = array();
                    for ($j = 0; $j < count($keys); $j++) {
                        if ($keys[$j] != "") {
                            $arr[$keys[$j]] = $values[$j];
                        }
                    }

                    $content[$i] = $arr;
                    $i++;
                }
            }
        }
        fclose($file);
        return $content;
    }

}
?>

这就是观点：

function readExcel() {
    $this->load->library('csvreader');
    $result = $this->csvreader->parse_file('Test.csv');
    $data['csvData'] = $result;
    $this->load->view('view_csv', $data);
}

答案 2 :(得分：2)

好吧不要介意我，我只是修改了ajmedway的库以包含分隔符，以防万一你想从TSV或管道分隔文件中获取数据。如果你想要普通的旧CSV，他就可以了。 

class CSVReader {

var $fields;/** columns names retrieved after parsing */
var $separator = ';';/** separator used to explode each line */
var $enclosure = '"';/** enclosure used to decorate each field */
var $max_row_size = 4096;/** maximum row size to be used for decoding */

function parse_file($p_Filepath, $delimiter = FALSE ) {

    $file = fopen($p_Filepath, 'r');
    $this->fields = fgetcsv($file, $this->max_row_size, $this->separator, $this->enclosure);
    if ($delimiter==FALSE)
    {
    $keys = str_getcsv($this->fields[0]);

    $i = 1;
    while (($row = fgetcsv($file, $this->max_row_size, $this->separator, $this->enclosure)) != false) {
        if ($row != null) { // skip empty lines
            $values = str_getcsv($row[0]);
            if (count($keys) == count($values)) {
                $arr = array();
                for ($j = 0; $j < count($keys); $j++) {
                    if ($keys[$j] != "") {
                        $arr[$keys[$j]] = $values[$j];
                    }
                }

                $content[$i] = $arr;
                $i++;
            }
        }
    }
    }
    else{
        $keys = str_getcsv($this->fields[0],$delimiter);

        $i = 1;
        while (($row = fgetcsv($file, $this->max_row_size, $this->separator, $this->enclosure)) != false) {
            if ($row != null) { // skip empty lines
                $values = str_getcsv($row[0],$delimiter);
                if (count($keys) == count($values)) {
                    $arr = array();
                    for ($j = 0; $j < count($keys); $j++) {
                        if ($keys[$j] != "") {
                            $arr[$keys[$j]] = $values[$j];
                        }
                    }

                    $content[$i] = $arr;
                    $i++;
                }
            }
        }
    }

    fclose($file);
    return $content;
}}?>
