php712安裝

❶ centos 7.2 系統 php7.0.12的 curl 擴展怎麼開啟

curl是一個廣泛使用的用來上傳和下載的命令行工具，當然嚴格來講，它還可以有別的用途。對於測試來講，它是Web相關測試非常實用的工具，包括debugging，使用起來非常方便。

下面直接進入主題：
1、直接進入到php源碼包中找到原先安裝PHP的源碼包文件①；
2、直接進入/usr/package/php-7.1.10/ext/curl目錄②；
cd /usr/package/php-7.1.10/ext/curl

3、通過phpize工具生成configure文件③；
/usr/local/php/bin/phpize

4、將安裝的軟體進行配置,檢查當前的環境是否滿足要安裝軟體的依賴關系④；
./configure --with-php-config=/usr/local/php/bin/php-config

5、編譯程序並安裝文件；
make &&make install

6、在php的配置文件php.ini最後一行添加extension=curl.so即可。

❷ php 關於intval函數！

第二個參數是指定第一個參數的進制，比如intval("12",5)就是把「12」當成5進制的數，然後把這個5進制的數轉換成10進制整數。

intval("12",5) = 7; (5進制的12=10進制7)
intval("1011",2) = 11; (2進制的1011=10進制11)

❸ php輸出年齡段，最小年齡12，最大60歲，顯示如 12歲-24歲，25歲-36歲....

<?php

*/
classTestAge
{
/**
*@param$youngAge最小年齡
*@param$oldAge最大年齡
*@param$ageRange分段年齡區間
*@returnarray
*/
publicfunctiongetAgeToArray($youngAge,$oldAge,$ageRange){
$a=array();
$c=array();
$yage=$youngAge;
$ageRangeNum=ceil(($oldAge-$youngAge)/$ageRange);
for($youngAge;$youngAge<=$oldAge;$youngAge++){
array_push($a,$youngAge);
}
for($i=1;$i<=$ageRangeNum;$i++){
foreach($aas$k=>$v){
if($a[$k]<$yage+$ageRange*$i&&$a[$k]>=$yage+$ageRange*($i-1)){
$c[$i][]=$v;
}
}
}
return$c;
}
}

$ob=newTestAge();
$result=$ob->getAgeToArray(12,60,5);
var_mp($result);

//沒事干替你寫了個全部的功能函數 寫代碼類 記得給好評

❺ <php $arr = array(5 => 1, 12 => 2,2 => 3); $arr[] = 56; 請問此處中括弧中的鍵名是3嗎$arry[3]=56.

<?php $arr = array(5 => 1, 12 => 2,2 => 3); $arr[] = 56; 請問此處中括弧中的鍵名是3嗎？

這里不是3 而是13，因為 array(5 => 1, 12 => 2,2 => 3) 裡面，關聯數組 數字ID鍵名最大是12，
$arr[] = 56; 這里再加一個鍵，就是13了。
