用 preg_replace 替换一些数组（第一行不起作用）

Question

我正在编写一些代码，您可以通过这些代码上传 txt 文件并在数组中读取该文件。现在我想用 preg_replace 更改该数组的某些行，但第一个数组不会更改。

这是代码http://pastebin.com/jkxAE1h5

HTML：

<form method="post" enctype="multipart/form-data">
<input name="my_text[]" type="file" />
<input type="submit" />

PHP：

<?php
$geladene_seite = $_FILES['my_text']['tmp_name'][0];
$array_liste = array(0);
$my_text_file = file($geladene_seite);

foreach ($my_text_file as $single_file) {
  $single_file = trim($single_file);    //  leerzeichen entfernen
  if (strlen($single_file) > 0){
    $single_file = str_replace(chr(10), '', $single_file);
    $single_file = str_replace(chr(13), '', $single_file);
    $menge = array_push ($array_liste, $single_file);
  }
}

echo '<hr><pre>';
print_r ($array_liste);
echo '</pre>';

$text1 = str_replace($array_liste[1], '<b>'.$array_liste[1].'</b>', $array_liste[10]);
$text2 = str_replace($array_liste[2], '<b>'.$array_liste[2].'</b>', $array_liste[11]);
$text3 = str_replace($array_liste[3], '<b>'.$array_liste[3].'</b>', $array_liste[12]);

echo '<p>'.$text1.'</p>';
echo '<p>'.$text2.'</p>';
echo '<p>'.$text3.'</p>';

?>

示例数据：

text one
text two
text three

this is for description one
this is for description two
this is for description three

header for number one
header for number two
header for number three

many more infos for the text one many more infos for the text one many more infos for the text one many more infos for the text one many more infos for the text one many more infos for the text one
many more infos for the text two many more infos for the text two many more infos for the text two many more infos for the text two many more infos for the text two many more infos for the text two
many more infos for the text three many more infos for the text three many more infos for the text three many more infos for the text three many more infos for the text three many more infos for the text three

您的问题在这里：

$array_liste = array(0);

将其更改为：

$array_liste = array();
