我的数组看起来像这样:
Array
(
[1] => Array
(
[0] => /webmail/
[1] => 42024
[2] => 246538196
[3] => 72
[4] => 70
)
[2] => Array
(
[0] => /public/index.php
[1] => 6022
[2] => 2575777
[3] => 40
[4] => 153
)
[3] => Array
(
[0] => /
[1] => 293
[2] => 5326453
[3] => 184
[4] => 76
)
[4] => Array
(
[0] => /webmail/skins/larry/watermark.html
[1] => 248
[2] => 40225
[3] => 0
[4] => 2
)
[5] => Array
(
[0] => /webmail/program/resources/blank.tif
[1] => 182
[2] => 29406
[3] => 0
[4] => 1
)
等等...当我想删除以 .tif/.js/.css/.woff 结尾的每个元素时,我只使用 :
$key = array_search('*.tif',$sider); // for example for .tif
unset($sider[$key]);
但它不起作用!我的代码中有什么问题以及如何删除多个条件,例如所有以 .tif/.js/.css/.woff 结尾的字符串。
谢谢
>array_search
不起作用,因为数组的每个元素都是一个数组,而数组与"*.tif"不匹配。此外,array_search
不支持像 *
这样的通配符。数组过滤器是这里的典型方法:
$sider = array_filter($sider, function (array $element) {
return !preg_match('/.tif$/i', $element[0]);
});
循环遍历值,如果扩展名位于不允许的扩展数组中,则取消设置元素。
$remove_extensions = array('tif', 'js');
foreach($arr as $key => $value) {
if(in_array(pathinfo($value[0], PATHINFO_EXTENSION), $remove_extensions)) { unset($arr[$key]); }
}
<?php
function removeDeep($array, $pattern) {
$r = array();
if (!is_array($array)) {
trigger_error(__FUNCTION__ . ' expected paramater 1 to be an array.', E_USER_WARNING);
return false;
}
foreach ($array as $key => $value) {
if (is_array($value)) {
$r[$key] = call_user_func(__FUNCTION__, $value, $pattern);
continue;
}
if (!preg_match($pattern, $value)) {
$r[$key] = $value;
}
}
return $r;
}
$sider = removeDeep( $sider, "*.tif");
?>
试试 smth like
var_dump(
array_filter(
$array,
function ($row) {
return preg_match('/.(tif|css|js|woff))$/i', $row[0]) === 1;
}
)
);
