How to remove multiple UTF-8 BOM sequences

Question

Using PHP5 (cgi) to output template files from the filesystem and having issues spitting out raw HTML.

private function fetch($name) {
    $path = $this->         


        

Answer 1

try:

// -------- read the file-content ----
$str = file_get_contents($source_file); 

// -------- remove the utf-8 BOM ----
$str = str_replace("\xEF\xBB\xBF",'',$str); 

// -------- get the Object from JSON ---- 
$obj = json_decode($str);

Answer 2

When working with faulty software it happens that the BOM part gets multiplied with every saving.

So I am using this to get rid of it.

function remove_utf8_bom($text) {
    $bom = pack('H*','EFBBBF');
    while (preg_match("/^$bom/", $text)) {
        $text = preg_replace("/^$bom/", '', $text);
    }
    return $text;
}

Answer 3

Another way to remove the BOM which is Unicode code point U+FEFF

$str = preg_replace('/\x{FEFF}/u', '', $file);

Answer 4

if anybody using csv import then below code useful

$header = fgetcsv($handle);
foreach($header as $key=> $val) {
     $bom = pack('H*','EFBBBF');
     $val = preg_replace("/^$bom/", '', $val);
     $header[$key] = $val;
}

Answer 5

you would use the following code to remove utf8 bom

//Remove UTF8 Bom

function remove_utf8_bom($text)
{
    $bom = pack('H*','EFBBBF');
    $text = preg_replace("/^$bom/", '', $text);
    return $text;
}

Answer 6

An extra method to do the same job:

function remove_utf8_bom_head($text) {
    if(substr(bin2hex($text), 0, 6) === 'efbbbf') {
        $text = substr($text, 3);
    }
    return $text;
}

The other methods I found cannot work in my case.

Hope it helps in some special case.
