将函数应用于数组中的每个元素(O'Reilly 食谱示例)
applying a Function to Each element in an array (O'Reilly cookbook example)
对于嵌套数据。
我试过了
<?php
$names = array('firstnames' => array("Baba", "Billy"),
'lastnames' => array("O'Riley", "O'Reilly"));
array_walk_recursive($names, function (&value, $key) {
$value = htmlentities($value, ENT_QOUTES);
})
foreach ($names as $nametypes) {
foreach ($nametypes as $name) {
print "$name\n";
}
}
?>

但我不断收到消息
T_String,预计 T_Variable
您的代码中有拼写错误(ENT_QUOTES,$value):
array_walk_recursive($names, function(&$value, $key) {
$value = htmlentities($value, ENT_QUOTES);
});
foreach ($names as $nametypes) {
foreach ($nametypes as $name) {
print "$name\n";
}
}
使用 &$value
而不是 &value
使用 ENT_QUOTES 而不是 ENT_QOUTES
它正在工作。
谢谢大家
