1 php搜索多維數(shù)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';
$foo['info'][1] = 'bar 5';
如果要查找 bar 3 怎么進(jìn)行查找呢。有三個(gè)結(jié)果,而這三個(gè)結(jié)果都要,看下面的函數(shù):
-------------------------------------------------------------------------------------------------------------------------------
function array_search_re($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(gè)函數(shù)就可以把上面要查找到的內(nèi)容全部返回出鍵名來(lái)
$result = array_search_re('bar 3', $foo);
print_r($result);
輸出結(jié)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(shù)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(jié)果為如下:

最近網(wǎng)站排名出現(xiàn)變動(dòng),幾個(gè)排名一直穩(wěn)定在百度前三的關(guān)鍵詞出現(xiàn)下降,甚至完全被k的情況,經(jīng)過(guò)分析,發(fā)現(xiàn)是收到友情鏈接的牽連,有三個(gè)友鏈網(wǎng)站被k,對(duì)方鏈回我的那個(gè)關(guān)鍵詞排名直接沒(méi)有。
剛好我也想把 中山網(wǎng)站建設(shè)?這個(gè)關(guān)鍵詞設(shè)為主關(guān)鍵詞,以前由于其他詞的排名都比較穩(wěn)定,不敢輕易修改,怕其他的收到影響,這次趁此機(jī)會(huì)一起改了,看看效果如果,驗(yàn)證一下? 網(wǎng)站排名下降時(shí)是否是修改關(guān)鍵詞的時(shí)機(jī),也給其他站長(zhǎng)做一個(gè)參考。

在別的服務(wù)器運(yùn)行我的網(wǎng)站程序的時(shí)候,出現(xiàn)了Field 'id' doesn't have a default value 的提示,意思是這個(gè)值我沒(méi)有提交數(shù)據(jù),并且數(shù)據(jù)庫(kù)結(jié)構(gòu)沒(méi)有設(shè)置默認(rèn)值,由于對(duì)方的mysql服務(wù)器開(kāi)啟了STRICT_TRANS_TABLES嚴(yán)格模式,所以報(bào)錯(cuò)了
解決方法是:
如果自己的服務(wù)器,有權(quán)限修改my.ini的話,打開(kāi)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(dāng)然不可能實(shí)現(xiàn),所以根本的解決方法還是修改自己的數(shù)據(jù)結(jié)構(gòu),把非空的字段加上默認(rèn)值,以后設(shè)計(jì)數(shù)據(jù)庫(kù)要注意這一點(diǎn),方便程序的移植

已經(jīng)assign一個(gè)模版變量$assign,由于要做特殊的循環(huán)輸出,使用for循環(huán),因此使用到了php標(biāo)簽,但是php語(yǔ)句和模版語(yǔ)句的變量作用域是不同的,因此不能直接獲取到
{{php}}
for($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(gè)對(duì)象里面;只要在for之前進(jìn)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>
