php多維數(shù)組的搜索

lin — Mon, 17 Dec 2012 12:48:04 +0000

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 怎么進行查找呢。有三個結(jié)果，而這三個結(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
$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：
?

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

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

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

smarty模版使用php標簽，如何獲取模版變量

lin — Sat, 22 Sep 2012 03:54:23 +0000

已經(jīng)assign一個模版變量$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

for($i=0;$i echo '

'.$assign[$i][title].'

'.$assign[$i+1][title].'

';}
{{/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 echo '

'.$assign[$i][title].'

'.$assign[$i+1][title].'

';}
{{/php}}

php清空某個目錄的方法

phpmyadmin導出的sql如何通過php導入

lin — Mon, 04 Jun 2012 04:15:01 +0000

以下函數(shù)可以直接把從phpmyadmin導出的sql文件直接通過php插入數(shù)據(jù)庫：

//$file表示通過讀取sql文件返回的字符串，比如$file2=file_get_contents('db.sql');

function import($file2){

$Db = new Db();
$file2=explode("\n",$file2);//將文件內(nèi)容按行讀入到數(shù)組

$c1=count($file2);
for($j=0;$j<$c1;$j++)
{
$ck=substr($file2[$j],0,4);//取每行的前4個字符
if( ereg("#",$ck)||ereg("--",$ck) )//去掉注釋
{
continue;
}
$arr[]=$file2[$j];//將去掉注釋的文件內(nèi)容按行讀入數(shù)組$arr,數(shù)組每個元素對應一行
}
$read=implode("\n",$arr); //重新組織文件內(nèi)容到一個字符串,(按照原來分好的一行一行的)
$sql=str_replace("\r",'',$read);//去掉"\r(回車符)"

$detail=explode(";\n",$sql);
//將經(jīng)上述整理過的文件內(nèi)容再次按一條完整的sql語句(以;和\n分隔)導入到數(shù)組$detail,
//此時數(shù)組detail的每個元素對應一條完整的sql語句
$count=count($detail);
for($i=0;$i<$count;$i++)
{
$sql=str_replace("\r",'',$detail[$i]);//去掉每行sql中的回車符
$sql=str_replace("\n",'',$sql);//去掉換行符
$sql=trim($sql);//去掉前后空格
//現(xiàn)在的$sql
$Db->query($sql);

}

php date函數(shù)的時區(qū)問題，輸出時間有誤

lin — Sat, 02 Jun 2012 02:16:24 +0000

問題：echo date('o-m-j H:i'); 輸出結(jié)果與本地時間相差8小時。
原因：時區(qū)未正確設置。
兩種解決方法:

1.加入date_default_timezone_set('Asia/Shanghai');
2. 修改php.ini
[Date]
; Defines the default timezone used by the date functions
date.timezone = PRC 注:PRC為中化人民共和國

php采集程序，提取網(wǎng)頁超鏈接，郵箱或其他特定內(nèi)容

以下代碼從上一篇文章修改而來，專門用于提取網(wǎng)頁所有超鏈接，郵箱或其他特定內(nèi)容

//采集網(wǎng)頁
function pick($url,$ft,$th)
{
$c=fetch_urlpage_contents($url);
foreach($ft as $key => $value)
{
$rs[$key]=fetch_match_contents($value["begin"],$value["end"],$c);
if(is_array($th[$key]))
{ foreach($th[$key] as $old => $new)
{
$rs[$key]=str_replace($old,$new,$rs[$key]);
}
}
}
return $rs;
}

$url="http://m.jartj.cn"; //要采集的地址
$ft["a"]["begin"]='
$ft["a"]["end"]='>'; //截取的結(jié)束點

$rs=pick($url,$ft,$th); //開始采集

print_r($rs["a"]);
