PHP分号分隔文件生成

Question

我正在使用此代码生成分号分隔的文件:

for ($i = 0; $i < 3; $i = $i+1)
{   
array_push($dataArray,"$dataCell1","$dataCell2","$dataCell3","$dataCell4","$dataCell5","$dataCell6","$dataCell7","$dataCell8","$dataCell9","$dataCell10","$dataCell11");

$stringData = rtrim(implode(';', $dataArray), ';'); //rtrim will prevent the last cell to be imploded by ';'            

$stringData .= "\r\n";
}   

我想要的是:

(数据用分号隔开，行用newLine隔开)
我得到的是:

(数据用分号分隔但不添加新行，所有数据都显示在单行中)
请告诉我我做错了什么..

Answer 1

你的问题在于你的逻辑。您在每次迭代中继续将数据添加到 $dataArray 中，而代码中的以下语句会将 stingData 设置为 $dataArray 的内爆值仅在最后一个循环迭代中 .那时， $dataArray 包含所有数据值，因为您不断向它推送 3 次迭代。

$stringData = rtrim(...)

你想要做的是:

<?php

//concatenation string
$stringData = '';

for ($i = 0; $i < 3; $i = $i+1)
{ 
    //init the array with every iteration. 
    $dataArray = array();

    //push your values
    array_push($dataArray,"$dataCell1","$dataCell2","$dataCell3","$dataCell4","$dataCell5","$dataCell6","$dataCell7","$dataCell8","$dataCell9","$dataCell10","$dataCell11");

    //concatenate
    $stringData  .= rtrim(implode(';', $dataArray), ';'); 

    //new line
    $stringData .= "\r\n";
} 

//print
echo $stringData . "\n";
?>
