使用preg_replace替換某些數組（第一行不起作用）

Question

我正在腳本化一些代碼，您允許您上傳一個txt文件並將其讀入數組中。現在我想用preg_replace改變這個數組的某一行，但第一個數組不會改變。

這裏是代碼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>'; 

?> 

樣本數據：

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

你的問題是在這裏：

$array_liste = array(0); 

將其更改爲：

$array_liste = array();
