我的数组中的一些元素是基于用户提交的空字符串。我需要移除这些元素。我有这个:
foreach($linksArray as $link)
{
if($link == '')
{
unset($link);
}
}
print_r($linksArray);
但这并不奏效。$linksArray仍然有空元素。我也尝试过用empty()函数这样做，但结果是一样的。
当前回答
$my = ("0"=>" ","1"=>"5","2"=>"6","3"=>" ");
foreach ($my as $key => $value) {
if (is_null($value)) unset($my[$key]);
}
foreach ($my as $key => $value) {
echo $key . ':' . $value . '<br>';
}
输出
1:5 2:6
其他回答
foreach($linksArray as $key => $link)
{
if($link === '')
{
unset($linksArray[$key]);
}
}
print_r($linksArray);
试试这个** * *的例子
$or = array(
'PersonalInformation.first_name' => $this->request->data['User']['first_name'],
'PersonalInformation.last_name' => $this->request->data['User']['last_name'],
'PersonalInformation.primary_phone' => $this->request->data['User']['primary_phone'],
'PersonalInformation.dob' => $this->request->data['User']['dob'],
'User.email' => $this->request->data['User']['email'],
);
$or = array_filter($or);
$condition = array(
'User.role' => array('U', 'P'),
'User.user_status' => array('active', 'lead', 'inactive'),
'OR' => $or
);
$out_array = array_filter($input_array, function($item)
{
return !empty($item['key_of_array_to_check_whether_it_is_empty']);
}
);
$a = array(1, '', '', '', 2, '', 3, 4);
$b = array_values(array_filter($a));
print_r($b)
只有一句话: 更新(感谢@suther):
$array_without_empty_values = array_filter($array);
