PHP數組顯示值和變量

Question

$states = array( 
     "NSW" => "NSW", 
     "VIC" => "VIC", 
     "QLD" => "QLD", 
     "SA" => "SA", 
     "WA" => "WA", 
     "TAS" => "TAS", 
     "NT" => "NT", 
     "ACT" => "ACT", 
     "OTH" => "OTH (AUS)", 
     "OVS" => "OVS (Overseas)" 
     ); 

現在我想要的值是select和變量的值。

foreach ($states as $key => $value) { 
    $form_ret .= "<option value='".$key."'>".$key[1]."</option>"; 
} 

，但我不能得到OVS (Overseas)從OVS準確值..

我真正想要得到的是這樣的：

<select name="State" id="State" > 
<option value="NSW">NSW </option> 
<option value="VIC">VIC </option> 
<option value="QLD">QLD </option> 
<option value="SA">SA </option> 
<option value="WA">WA </option> 
<option value="TAS">TAS </option> 
<option value="NT">NT </option> 
<option value="ACT">ACT </option> 
<option value="OTH">OTH (AUS)</option> 
<option value="OVS">OVS (Overseas)</option> 
</select> 

有沒有人有一個想法，我案件？在此先感謝

Answer 1

替代$key[1]爲$value：

foreach ($states as $key => $value) { 
    $form_ret .= "<option value='".$key."'>".$value."</option>"; 
} 

Answer 2

我想你想用$value，而不是$key[1]

foreach ($states as $key => $value) { 
    $form_ret .= "<option value='".$key."'>".$value."</option>"; 
} 

Answer 3

鍵[1]是不是值正確。它代表字符在你的關鍵的串1

必須使用$值顯示右

Answer 4

echo '<select name="State" id="State">'; 
foreach ($states as $key => $value){ 
echo '<option value="'.$key.'">'.$value.'</option>'; 
}echo '</select>'; 

這是HTML的是，你應該得到

<select id="State" name="State"> 
    <option value="NSW">NSW</option> 
    <option value="VIC">VIC</option> 
    <option value="QLD">QLD</option> 
    <option value="SA">SA</option> 
    <option value="WA">WA</option> 
    <option value="TAS">TAS</option> 
    <option value="NT">NT</option> 
    <option value="ACT">ACT</option> 
    <option value="OTH">OTH (AUS)</option> 
    <option value="OVS">OVS (Overseas)</option> 
    </select>
