从包含文件调用时，PHP preg_replace不替换

I am using Linux (14.04.2 LTS trusty).

In my PHP script, I output data (varchar) retrieved from several columns within a MySQL table.

The data in some columns contains new lines/paragraphs, spaces, periods, and many other characters. For example, here is one of the values I am working with:

var_dump($value2) shows string(16) " redness."

For some columns, I enter the following code to remove certain unwanted data before outputting...

$value3 = preg_replace('#[ \,\";\.
]#', '', $value2);
echo $value3;

which outputs: redness ...it works.

Realizing that I use the code above often (along with additional code not presented here), I decided to create a function that includes it and then call the function (which is included from another file) to output the remaining columns.

However, when I call the function, and does not seem to work and the output displays those characters literally:

redness

Based on answers to related questions in this forum, I tried the following:

$value3 = preg_replace('#[ \\|\\\\ |\\ |\,|\"|;|\.]#', '', $value2);

which outputs: edess

focusing on the and , I tried $value3 = preg_replace('#[ ]+#', '', $value2);

which outputs: redness.

I also tried $value3 = str_replace(array(" ", ""), '', $value2);

which outputs: redness.

I tried $value3 = trim(preg_replace('/\s\s+/', ' ', $value2));

which outputs: redness.

I tried $value3 = preg_replace('/\s+/', '', $value2);

which outputs: redness.

I tried echo preg_replace('/[ ]/','',$value2);

which outputs: redness.

I tried echo preg_replace('/(\)(\ )/','',$value2);

which outputs redness.

Why does preg_replace not remove and/or if I call it from a function within an included file?

See Comments. I had created an array to store the column names from the database's table...

$Command = "DESCRIBE {$Table}";
$Command = mysqli_query($mysqli, $Command) or die("Error: ".mysqli_error($mysqli));

if($Command)
{
    $TableField = array();

    while($row = mysqli_fetch_array($Command)) 
    {
        $TableField[] = $row['Field'];
    }
}

...But the array that stores the values was assigned the incorrect keys:

while($newArray = mysqli_fetch_array($Execute)) foreach($TableField as $key => $value) {$GoodData[$key] = $newArray[$key];}

...The problem disappeared when the array was assigned the correct keys:

while($newArray = mysqli_fetch_array($Execute)) {foreach($TableField as $key => $value) {$GoodData[$value] = $newArray[$value];}
