所有 csv 导出数据都在一列中

Question

我有 csv 导出代码，我正在使用，但问题是所有数据都在 csv 中导出为一列。但我需要数据必须是列分隔的，

 
 <?php
 $results= array(0=>array(name => "anil",agency=>"",phone=>"234235",cname=>"Atleta"),1=>array(name => "anil",agency=>"",phone=>"234235",cname=>"Atleta"));
 $column = array("name","cname","agency","phone");
		$writecolumn = array("Nome do Artista","Categoria","Agencia","Telefone");
		$csv_export='';
		for($i = 0; $i < count($column); $i++)
		{
		    $csv_export.= $writecolumn[$i]."\t" ;
		}
		$csv_export.= "\n";
		for($j = 0; $j < count($results); $j++)
		{
		    for($i = 0; $i < count($column); $i++)
		    {
			$csv_export.= $results[$j][$column[$i]]."\t"; 
		    } 
		    $csv_export.= "\n";
		}		
	  
	    $categoryname=$results[0]['cname'];
	    $filename = $categoryname."-Category-Artist-Data.csv";
	    header('Content-type: application/csv');
	    header('Content-Disposition: attachment; filename='.$filename);
	    echo $csv_export;
	    exit;        
    ?>

您的代码有分隔符（值分隔符）是“制表符”（“\t”）。可能是您的 CSV 阅读软件需要一些配置才能开始使用 'tab' ('\t') 作为分隔符。我在下面更新了您的代码并使用“，”作为分隔符。 Microsoft Excel 使用“,”作为默认分隔符。请尝试以下代码，

 
 <?php
                $results= array(0=>array('name' => "anil",'agency'=>"",'phone' =>"234235",'cname'=>"Atleta"),1=>array('name' => "anil",'agency'=>"",'phone'=>"234235",'cname'=>"Atleta"));
                $column = array("name","cname","agency","phone");
		$writecolumn = array("Nome do Artista","Categoria","Agencia","Telefone");
		$csv_export='';
		for($i = 0; $i < count($column); $i++)
		{
		    $csv_export.= $writecolumn[$i]."," ;
		}
		$csv_export.= "\r\n";
		for($j = 0; $j < count($results); $j++)
		{
		    for($i = 0; $i < count($column); $i++)
		    {
			$csv_export.= $results[$j][$column[$i]].","; 
		    } 
		    $csv_export.= "\r\n";
		}		
	  
	    $categoryname=$results[0]['cname'];
	    $filename = $categoryname."-Category-Artist-Data.csv";
	    header('Content-type: application/csv');
	    header('Content-Disposition: attachment; filename='.$filename);
	    echo $csv_export;
	    exit;        
    ?>

使用array_reduce，通过对每个元素应用函数，将数组简化为单个值，并将初始值作为第三个参数传递，类似这样：

$result= array(0=>array(name => "anil",agency=>"",phone=>"234235",cname=>"Atleta"),1=>array(name => "name_anil",agency=>"agency2",phone=>"234235",cname=>"Atleta_2"));
$csv_export = array_reduce($result, function($acc,$row) {
    foreach($row as $key => $value) {
        $acc .= $value;
        $acc .= "\t";
        }
    $acc .= "\n";
    return $acc;
    },
    "Nome do Artista\tCategoria\tAgencia\tTelefone\n")
$categoryname=$results[0]['cname'];
$filename = $categoryname."-Category-Artist-Data.csv";
header('Content-type: application/csv');
header('Content-Disposition: attachment; filename='.$filename);
echo $csv_export;
exit;
