PHP删除数组(array一维)中指定的某个值
PHP删除数组(array一维)中指定的某个值
根据指定的值删除:
$student = array("name"=>"张三","sex"=>"男","math"=>"85","english"=>"65");
$k = array_search("65",$student);
unset($student[$k]);
echo "<pre>";
print_r($student);
echo "</pre>";
结果:
Array
(
[name] => 张三
[sex] => 李四
[math] => 85
)
根据制定的键删除:
$student = array("name"=>"张三","sex"=>"男","math"=>"85","english"=>"65");
unset($student['name']);
echo "<pre>";
print_r($student);
echo "</pre>";
结果:
Array
(
[sex] => 男
[math] => 85
[english] => 65
)
其实..根据 值删除. 也是先找到键. 然后根据键进行删除
