Use array_filter. You can provide a callback which decides which elements remain in the array and which should be removed. (A return value of falsefrom the callback indicates that the given element should be removed.) Something like this:
使用array_filter. 您可以提供一个回调来决定哪些元素保留在数组中，哪些应该被删除。（false回调的返回值表示应该删除给定的元素。）像这样：
$search_text = 'Bread';
array_filter($array, function($el) use ($search_text) {
return ( strpos($el['text'], $search_text) !== false );
});

is there a reason for multi array. is id unique and can it be used as index.
多阵列有原因吗？id 是唯一的，可以用作索引。
$data=array(
array(
'text' =>'I like Apples',
'id' =>'102923'
)
,
array(
'text' =>'I like Apples and Bread',
'id' =>'283923'
)
,
array(
'text' =>'I like Apples, Bread, and Cheese',
'id' =>'3384823'
)
,
array(
'text' =>'I like Green Eggs and Ham',
'id' =>'4473873'
)
);
$findme='bread';
$findme='面包';
foreach ($data as $k=>$v){
if(stripos($v['text'], $findme) !== false){
echo "id={$v[id]} text={$v[text]}<br />"; // do something $newdata=array($v[id]=>$v[text])
}
}
