如何从数组中的所有索引中获取特定值
How to get specific values out of all indexes in an array
我有一个数组,我想对其进行迭代以将项目推入 select 框中,但我不知道该怎么做。
我从函数中得到的数组:
array(2) {
["de"]=> array(10) {
["id"]=> int(10)
["order"]=> int(1)
["slug"]=> string(2) "de"
["locale"]=> string(5) "de-DE"
["name"]=> string(7) "Deutsch"
["url"]=> string(34) "http://localhost/werk/Mol/de/haus/"
["flag"]=> string(66) "http://localhost/werk/Mol/wp-content/plugins/polylang/flags/de.png"
["current_lang"]=> bool(false)
["no_translation"]=> bool(false)
["classes"]=> array(4) {
[0]=> string(9) "lang-item"
[1]=> string(12) "lang-item-10"
[2]=> string(12) "lang-item-de"
[3]=> string(15) "lang-item-first"
}
}
["nl"]=> array(10) {
["id"]=> int(3)
["order"]=> int(2)
["slug"]=> string(2) "nl"
["locale"]=> string(5) "nl-NL"
["name"]=> string(10) "Nederlands"
["url"]=> string(26) "http://localhost/werk/Mol/"
["flag"]=> string(66) "http://localhost/werk/Mol/wp-content/plugins/polylang/flags/nl.png"
["current_lang"]=> bool(true)
["no_translation"]=> bool(false)
["classes"]=> array(4) {
[0]=> string(9) "lang-item"
[1]=> string(11) "lang-item-3"
[2]=> string(12) "lang-item-nl"
[3]=> string(12) "current-lang"
}
}
}
我尝试了 foreach 但我只得到了数组的索引
<?php
$translations = pll_the_languages(array('raw' => 1));
$lang_codes = array();
foreach ($translations as $key => $value) {
array_push($lang_codes, $key);
}
?>
我需要语言 slug,URL,以及这个数组中所有索引的标志(de & nl),我该怎么办?
对外部数组进行简单的迭代,然后从子数组中选择您想要的值。
<?php
$translations = pll_the_languages(array('raw' => 1));
$lang_codes = array();
foreach ($translations as $lang => $info) {
$lang_codes[$lang] = [ 'slug' => $info['slug'],
'url' => $info['url'],
'flag' => $info['flag']
];
}
?>
你可以这样处理
$res = [];
foreach($translations as $key => $value){
$res[$key] = [
'slug' => $value['slug'],
'url' => $value['url'],
'flag' => $value['flag']
];
}
