Question

我正在尝试创建文件并逐行写入。尝试使用变量中的文件名创建文件时，它失败。但是，如果我对文件名进行硬编码，它就可以工作。

回声是：

无法打开/创建文件：CleanStatements \ Clean_IRS01HHTAX.TXT

这有效：

if ($handle) {
        $cleanFileHandle = fopen( "CleanStatements\\Clean_IRS01HHTAX.TXT", "w") or die("Unable to open/create file: ".$this->CleanFilePath);
        while (($line = fgets($handle)) !== false) {
            fwrite($cleanFileHandle, $line);
        }
        fclose($cleanFileHandle);
        fclose($handle);
    } else {
        // error opening the file.
    }

这不是

if ($handle) {
        $cleanFileHandle = fopen( $this->CleanFilePath, "w") or die("Unable to open/create file: ".$this->CleanFilePath);
        while (($line = fgets($handle)) !== false) {
            fwrite($cleanFileHandle, $line);
        }
        fclose($cleanFileHandle);
        fclose($handle);
    } else {
        // error opening the file.
    }

这是完整的课程：

/**
 * Class StatementFile
*/
class StatementFile
{
var $Name;
var $FilePath;
var $Type;
var $CleanFileName;
var $CleanFilePath;

function __construct($filePath){
    $this->Name = basename($filePath).PHP_EOL;
    $this->FilePath = 'Statements\\'.$filePath;
    $this->Type = null;
    $this->CleanFileName = "Clean_".$this->Name;
    $this->CleanFilePath = "CleanStatements\\" . $this->CleanFileName;
}

function cleanStatement(){
    $handle = fopen($this->FilePath, "r");
    echo "Opening file: ".$this->FilePath ."<br/>";
    if ($handle) {
        $cleanFileHandle = fopen( $this->CleanFilePath, "w") or die("Unable to open/create file: ".$this->CleanFilePath);
        while (($line = fgets($handle)) !== false) {
            // process the line read.
            // clean line here
            fwrite($cleanFileHandle, $line);
        }
        fclose($cleanFileHandle);
        fclose($handle);
    } else {
        // error opening the file.
    }
}

tl; dr

从PHP_EOL删除$this->Name

这只是一个猜测，但我敢打赌PHP_EOL不包含有效的文件名字符：

$this->Name = basename($filePath).PHP_EOL;
// which ultimate ends up concatenated in
$this->CleanFilePath

如果您确实真的出于任何原因将其保留在$this->name中，然后申请trim()

$cleanFileHandle = fopen( trim( $this->CleanFilePath ), "w") or die("Unable to open/create file: ".trim( $this->CleanFilePath) );

fopen不允许创建文件名变量
