连上数据库。
语法: int sybase_connect(string [servername], string [username], string [password]);
返回值: 整数
函数种类: 数据库功能
本函数用来打开与 Sybase 数据库的连接。参数 servername 为欲连上的数据库服务器名称。参数 username 及 password 可省略,分别为连接使用的帐号及密码。使用本函数需注意早点关闭数据库,以减少系统的负担。连接成功则返回数据库的连接代号,失败返回 false 值。
Php小问题 遍历二维数组
?php
$employee[]=array("jas,join","programmer",20);
$employee[]=array("june,join","programmer",20);
$employee[]=array("aili,join","programmer",20);
$employee[]=array("doe,jane","programmer",20);
$newname = array();
foreach ($employee as $record){
$newname[] = isset($record[0]) ? $record[0] : 'no name';
}
echo 'pre';
print_r($newname);
echo '/pre';

php如何将二维数组添加到数据库中,如何遍历
?php
$array = [1,2,3,4,5];
//序列化
$insert = serialize($array);
//SQL操作
...
//取出来的数据再反序列化
$data = unserialize($fetch);
?
PHP二维数组遍历问题
$res = array();
$t = array('123332','123333');
foreach ($ary as $v) {
foreach($t as $m) {
$res[$t][]=$v[$m];
}
}
print_r($res);
这样应该可以满足你的要求。
一般来说多维数组遍历的话,多个foreach嵌套使用。
多年以后,重看这个代码,发现一些问题,重复发一下吧!
$ary = [
['123332' = 123332, '123333' = 123333,],
['123332' = 'Hockey Stick', '123333' = 'Hockey Stick2',],
['123332' = 33.25, '123333' = 33.25,],
['123332' = 10, '123333' = 10,],
['123332' = 33.25, '123333' = 33.25,],
['123332' = 1, '123333' = 1,],
['123332' = 'AAAA6', '123333' = 'AAAA6',],
];
$res = [];
$t = ['123332', '123333',];
foreach ($ary as $v) {
foreach ($t as $m) {
$res[$m][] = $v[intval($m)];
}
}
print_r($res);
运行结果:
Array
(
[123332] = Array
(
[0] = 123332
[1] = Hockey Stick
[2] = 33.25
[3] = 10
[4] = 33.25
[5] = 1
[6] = AAAA6
)
[123333] = Array
(
[0] = 123333
[1] = Hockey Stick2
[2] = 33.25
[3] = 10
[4] = 33.25
[5] = 1
[6] = AAAA6
)
)
php中遍历二维数组的几种方式
?php
//使用for循环遍历
$arr2=array(array("张三","20","男"),array("李四","25","男"),array("王五","19","女"),array("赵六","25","女"));
echo "table border=2 bordercolor=redtrtd姓名/tdtd年龄/td gt;td性别/td/tr";
for($i=0;$i4;$i++){
echo "tr";
for($j=0;$j3;$j++){
echo "td";
echo $arr2[$i][$j];
echo "/td";
}
echo "/tr";
echo "br";
}
echo "/table";
?
//使用foreach遍历
?php
$arr = array('one'=array('name'='张三','age'='23','sex'='男'),
'two'=array('name'='李四','age'='43','sex'='女'),
'three'=array('name'='王五','age'='32','sex'='男'),
'four'=array('name'='赵六','age'='12','sex'='女'));
foreach($arr as $k=$val){
echo $val['name'].$val['age'].$val['sex']."br";
}
echo "p";
?
?php

'three'=array('name'='王五','age'='32','sex'='男'),
'four'=array('name'='赵六','age'='12','sex'='女'));
foreach($arr as $key=$value){
foreach($value as $key2=$value2){
echo $value2;
}
echo "br";
