PHP将值推入关联数组？
要将值推入关联数组，请使用方括号[][]。首先创建一个关联数组-
$details= array ( 'id' => '101', 'name' => 'John Smith', 'countryName' => 'US' );
PHP代码如下插入值-
示例
<!DOCTYPE html>
<html>
<body>
<?php
$details= array (
'id' => '101',
'name' => 'John Smith',
'countryName' => 'US'
);
$all_details['studentDetails'][] = $details;
print_r($all_details);
?>
</body>
</html>输出结果
Array (
[studentDetails] => Array (
[0] => Array (
[id] => 101 [name] => John Smith [countryName] => US
)
)
)
