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
$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 )

1,capture標(biāo)簽
capture的中文意思是抓取,它的作用是抓取模板輸出的數(shù)據(jù),當(dāng)我們需要它的時(shí)候,調(diào)用它,以得到抓取數(shù)據(jù)的目的。例子:
說明:
在{capture name=”test”}和{/capture}之間的內(nèi)容被存儲(chǔ)到變量$test中,該變量由name屬性指定.在模板中通過 $smarty.capture.test 訪問該變量.如果沒有指定name 屬性,函數(shù)默認(rèn)將使用”default” 作為參數(shù),這一點(diǎn)很jquery中的clone
2,config_load標(biāo)簽
config_load可以直接將文件中的內(nèi)容讀取出來,這樣可以省掉assign這一步。
上述過程中如果出現(xiàn)這樣的問題Warning: Smarty error: unable to read resource, 請(qǐng)查看一下,你的test.csv是不是放在smarty的配置目錄中,默認(rèn)配置目錄是configs
3,literal標(biāo)簽的使用
做web開發(fā),難免會(huì)寫一些JS,jquery代碼。js和jquery里面都會(huì){}這樣的符號(hào),smarty會(huì)不會(huì)把它理解成php的變量呢?如果你不加literal標(biāo)簽的話,smarty肯定會(huì)把它理解變量了,加了就不會(huì),例如:
4,php標(biāo)簽
當(dāng)你習(xí)慣了assign后,你有沒有想過,在模板文件里面直接寫php代碼呢,我想有的時(shí)候你肯定很想吧。例如:
5,strip標(biāo)簽
strip標(biāo)簽去除標(biāo)簽內(nèi)的空格和回車,這一點(diǎn)我覺得,做手機(jī)開發(fā)的朋友肯定用的到,因?yàn)槿强崭裼锌赡軙?huì)導(dǎo)致整個(gè)頁面錯(cuò)亂,甚至是一個(gè)空白頁面。手機(jī)屏幕小,估計(jì)用smarty的可能性也比較小。
6,fetch標(biāo)簽
fetch標(biāo)簽根php的file_get_contents挺想的,都可以把文件中的內(nèi)容讀出來,并且是個(gè)字符串的形勢(shì)

RewriteCond %{HTTP_HOST} !^$

這樣實(shí)現(xiàn)的結(jié)果是只能通過www.86956464.com,zui88.com來訪問站點(diǎn),用其他的HOST訪問都會(huì)顯示403Forbidden。
