PHP - 防止动态创建文本区域中的换行符

I have a form with sets of inputs that can be dynamically created -- see here.

In order to push the values gathered from these inputs to a .csv sheet and keep them together in a single cell, I am using the following PHP function. It gathers the content from the 3 inputs, saves it to the .csv in a single cell, and for every new iteration of inputs, it just separates the entries with a "//" but keeps it in the same cell (like this: President, 2015, I was the president// Vice President, 2014, I was the vice president).

PHP

$provincialInvolvement = $_POST["provincialInvolvement"];
$provincialInvolvementValues = "";
$e = 0;

foreach($provincialInvolvement as $piValue)
    {
        $provincialInvolvementValues .= $piValue;
        $e++;
        if($e % 3 == 0)
            {
                $provincialInvolvementValues .= "//";
            }

    }

My problem is because the last input is a textarea, if a line break is put in (someone hits the enter key) it breaks the form of the .csv and puts it on a new line.

I am trying to write a function onto the portion of my PHP that, as it logs the value into $provincialInvolvementValues it removes any linebreaks but I;m having no luck.

Here is the function problem is it doesn't log anything.

$provincialInvolvement = $_POST["provincialInvolvement"];
$provincialInvolvementValues = "";
$e = 0;

foreach($provincialInvolvement as $piValue)
    {
        $provincialInvolvementValues .= $piValue;
        $e++;
        $provincialInvolvementValues = preg_replace( "/(|
)/ ", "", $provincialInvolvementValues ); 
        return $provincialInvolvementValues;
        if($e % 3 == 0)
            {
                $provincialInvolvementValues .= "//";
            }

    }

    Maybe try this: preg_replace( "? \s*", "", $provincialInvolvementValues) - newlines are usually or so this might work better.

    Also, the return $provincialInvolvementValues; is probably wrong in the loop...
