php多維數組的搜索 http://www.sjkaoyan.com/blog/view-425.html http://www.sjkaoyan.com/blog/view-425.html#comments Mon, 17 Dec 2012 12:48:04 +0000 lin http://www.sjkaoyan.com/blog/?p=425 1 php搜索多維數組的鍵值

如下面例子:

$foo[1]['a']['xx'] = 'bar 1';
$foo[1]['b']['xx'] = 'bar 2';
$foo[2]['a']['bb'] = 'bar 3';
$foo[2]['a']['yy'] = 'bar 4';
$foo[3]['c']['dd'] = 'bar 3';
$foo[3]['f']['gg'] = 'bar 3';
$foo['info'][1] = 'bar 5';

如果要查找 bar 3 怎么進行查找呢。有三個結果,而這三個結果都要,看下面的函數:
-------------------------------------------------------------------------------------------------------------------------------
function array_search_re($needle, $haystack, $a=0, $nodes_temp=array()){
global $nodes_found;
$a++;
foreach ($haystack as $key1=>$value1) {
??? $nodes_temp[$a] = $key1;
??? if (is_array($value1)){???
????? array_search_re($needle, $value1, $a, $nodes_temp);
??? }
??? else if ($value1 === $needle){
????? $nodes_found[] = $nodes_temp;
??? }
}
return $nodes_found;
}
---------------------------------------------------------------------------------------------------------------------------------
這個函數就可以把上面要查找到的內容全部返回出鍵名來
$result = array_search_re('bar 3', $foo);

print_r($result);

輸出結果為如下:
Array ( [0] => Array ( [1] => 2 [2] => a [3] => bb )
?????? ?? [1] => Array ( [1] => 3 [2] => c [3] => dd )
?????? ?? [2] => Array ( [1] => 3 [2] => f [3] => gg )
???? ?? )

1 php搜索多維數組的鍵名

function array_search_key($needle, $haystack){
global $nodes_found;

foreach ($haystack as $key1=>$value1) {
?
?if ($key1=== $needle){
?
??$nodes_found[] = $value1;
???????
?? }
??? if (is_array($value1)){???
????? array_search_key($needle, $value1);
??? }
???
???
}

return $nodes_found;
}
$result = array_search_key('a', $foo);

print_r($result);

輸出結果為如下:
?

Array
(
??? [0] => Array
??????? (
??????????? [xx] => bar 1
??????? )

??? [1] => Array
??????? (
??????????? [bb] => bar 3
??????? )

??? [2] => Array
??????? (
??????????? [yy] => bar 4
??????? )

)

網站排名下降時是否是修改關鍵詞的時機 http://www.sjkaoyan.com/blog/view-422.html http://www.sjkaoyan.com/blog/view-422.html#comments Tue, 04 Dec 2012 06:34:33 +0000 lin http://www.sjkaoyan.com/blog/?p=422 最近網站排名出現變動,幾個排名一直穩定在百度前三的關鍵詞出現下降,甚至完全被k的情況,經過分析,發現是收到友情鏈接的牽連,有三個友鏈網站被k,對方鏈回我的那個關鍵詞排名直接沒有。

剛好我也想把 中山網站建設?這個關鍵詞設為主關鍵詞,以前由于其他詞的排名都比較穩定,不敢輕易修改,怕其他的收到影響,這次趁此機會一起改了,看看效果如果,驗證一下? 網站排名下降時是否是修改關鍵詞的時機,也給其他站長做一個參考。

mysql STRICT_TRANS_TABLES嚴格模式下提示Field 'id' doesn't have a default value http://www.sjkaoyan.com/blog/view-411.html http://www.sjkaoyan.com/blog/view-411.html#comments Wed, 26 Sep 2012 03:42:48 +0000 lin http://www.sjkaoyan.com/blog/?p=411 在別的服務器運行我的網站程序的時候,出現了Field 'id' doesn't have a default value 的提示,意思是這個值我沒有提交數據,并且數據庫結構沒有設置默認值,由于對方的mysql服務器開啟了STRICT_TRANS_TABLES嚴格模式,所以報錯了

解決方法是:

如果自己的服務器,有權限修改my.ini的話,打開my.ini,查找
sql-mode="STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"

修改為

sql-mode="NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"

然后重啟MYSQL

在別人的虛擬空間上當然不可能實現,所以根本的解決方法還是修改自己的數據結構,把非空的字段加上默認值,以后設計數據庫要注意這一點,方便程序的移植

smarty模版使用php標簽,如何獲取模版變量 http://www.sjkaoyan.com/blog/view-409.html http://www.sjkaoyan.com/blog/view-409.html#comments Sat, 22 Sep 2012 03:54:23 +0000 lin http://www.sjkaoyan.com/blog/?p=409 已經assign一個模版變量$assign,由于要做特殊的循環輸出,使用for循環,因此使用到了php標簽,但是php語句和模版語句的變量作用域是不同的,因此不能直接獲取到

{{php}}

for($i=0;$i<count($assign);$i=$i+2){
echo '
<ul>
<li> <span class="zz_pic"><a href="'._url('picture',array('col_key'=>'cert','pic_id'=>$assign[$i][pic_id])).'" title=""><img src="uploads/thumb_'.$assign[$i][pic].'" alt=""></a></span> <span class="zz_title"><a href="'._url('picture',array('col_key'=>'cert','pic_id'=>$assign[$i][pic_id])).'" title="">'.$assign[$i][title].'</a></span> </li>
<li> <span class="zz_pic"><a href="'._url('picture',array('col_key'=>'cert','pic_id'=>$assign[$i+1][pic_id])).'" title=""><img src="uploads/thumb_'.$assign[$i+1][pic].'" alt=""></a></span> <span class="zz_title"><a href="'._url('picture',array('col_key'=>'cert','pic_id'=>$assign[$i+1][pic_id])).'" title="">'.$assign[$i+1][title].'</a></span> </li>i>

</ul>';}
{{/php}}

解決的方法是:模版變量全部存在smarty的一個對象里面;只要在for之前進行賦值:$assign = $this->_tpl_vars[assign];

{{php}}
$assign = $this->_tpl_vars[assign];
for($i=0;$i<count($assign);$i=$i+2){
echo '
<ul>
<li> <span class="zz_pic"><a href="'._url('picture',array('col_key'=>'cert','pic_id'=>$assign[$i][pic_id])).'" title=""><img src="uploads/thumb_'.$assign[$i][pic].'" alt=""></a></span> <span class="zz_title"><a href="'._url('picture',array('col_key'=>'cert','pic_id'=>$assign[$i][pic_id])).'" title="">'.$assign[$i][title].'</a></span> </li>
<li> <span class="zz_pic"><a href="'._url('picture',array('col_key'=>'cert','pic_id'=>$assign[$i+1][pic_id])).'" title=""><img src="uploads/thumb_'.$assign[$i+1][pic].'" alt=""></a></span> <span class="zz_title"><a href="'._url('picture',array('col_key'=>'cert','pic_id'=>$assign[$i+1][pic_id])).'" title="">'.$assign[$i+1][title].'</a></span> </li>i>
