我正在尝试用带引号的字符串替换任何换行符，例如

$help = '"Hi this is a string and I really want to replace
any newlines that are within that string" "There are multiple strings all within one string that all need
to have their newlines replaces"';

各种方法我都试过了。问题是我无法摆脱行尾本身。否则，fgetcsv 函数返回单个数组。它需要是引号内的行尾/换行符。

$str = str_replace(PHP_EOL, '', $str);

好的，这是我的代码。下载 csv 文件。

<?php
    $username = 'username';
    $password = 'password';
    $loginURL = 'http://www.example.com/login';
    $contentURL = 'http://www.example.com/feedback.csv';

    // Initialize the curl
    $ch = curl_init();

    // Pass the curl some options
    curl_setopt($ch, CURLOPT_URL, $loginURL);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS, 'inp-email=' . $username . '&inp-pass=' . $password);
    curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookie.txt');
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

    // Execute the curl to login
    $store = curl_exec($ch);

    // Change the URL to the CSV and execute
    curl_setopt($ch, CURLOPT_URL, $contentURL);
    $content = curl_exec($ch);

    // Time to sanitise, first I want to remove any newlines from customers comments
    $content = '\"' .implode('"', explode(PHP_EOL, $content)) . '\"';

    // Return the file contents
    file_put_contents('feedback.csv', $content)

然后是抓取CSV文件并在此刻打印出来的文件...

<?php
    // Function to loop through CSV and build up array
    function readCSV($csvFile){
        $file_handle = fopen($csvFile, 'r');
        while (!feof($file_handle) ) {
            $csvlines[] = fgetcsv($file_handle, 0, "\t");
        }
        fclose($file_handle);
        return $csvlines;
    }

    // Set path to CSV file
    $csvFile = 'feedback.csv';

    // Read the CSV file and build array using readCSV function
    $csv = readCSV($csvFile);

    echo '<pre>';

    foreach($csv as $line){
        if(count($line) != 16){
            print_r($line);
        }
    }

    echo '</pre>';

所以重申一下，我正试图从这里出发:

$str = '"this string has no new lines"  "but this one does have new
lines to strip out"';

到:

$str = '"this string has no new lines"  "but this one does have new lines to strip out"';
