当一个值的值等于指定值时,是否有一种简单的方法可以在数组中获取一组值?
例如,我从数据库中检索此数组,其中包含网站上的活动语言: [$ active_lang]
Array
(
[0] => Array
(
[id] => 1
[code] => pt
[idiom] => Português
)
[1] => Array
(
[id] => 2
[code] => es
[idiom] => Espanhol
)
[2] => Array
(
[id] => 3
[code] => en
[idiom] => Inglês
)
)
然后我获取活动语言的内容: [$ records]
Array
(
[0] => Array
(
[id] => 1
[page_base_id] => 1
[language] => pt
[title] => Title pt
[subtitle] => Subtitle pt
[description] => Description pt
)
[1] => Array
(
[id] => 2
[page_base_id] => 1
[language] => es
[title] => Title es
[subtitle] => Subtitle es
[description] => Description es
)
[2] => Array
(
[id] => 3
[page_base_id] => 1
[language] => en
[title] => Title en
[subtitle] => Subtitle en
[description] => Description en
)
)
我现在需要的是一种在foreach
数组内的$active_lang
内回显正确内容的方法,并避免进行第二次循环以达到在{{1}内显示的正确语言数组。我目前正在使用此代码:
$records
有没有办法做这样的事情?
<div class="tab-content">
<?php
foreach ($active_lang as $lang) { ?>
<div class="tab-pane" id="tab_<?php echo $lang['code']; ?>">
<div class="row-fluid ">
<div class="span12">
<div class="control-group">
<div class="controls">
<label class="control-label">Ttile</label>
<input id="title_1_pt" type="text" class="span12 " value="
<?php
foreach($records_languages as $record){
if($record['language']==$lang['code']){
echo $record['title'];
}
}
?>
" />
</div>
</div>
</div>
</div>
</div>
<?php } ?>
</div>
答案 0 :(得分:1)
您可以在最开始创建新数组:
$records = array();
foreach ($records_languages as $record) {
$records[$record['language']] = $record;
}
然后使用
$records[$lang['code']]['title']
这样可以省去一些循环。
