匹配数组php中的字符串

Question

我有两个数组，它们检查它们之间是否匹配，然后根据是否匹配将 yes 插入数据库。其中一个数组一次需要 3 个元素，以与另一个静态元素进行比较。

代码中的问题是它正确比较了多数，但我仔细查看了数据库。有几个比较是不正确的。有没有更好的方法来构建我的代码，所以没有什么不正确的比较？

我发现当 $team_squad 中相邻的两个元素都假设为“是”时，会发生未命中匹配。

这个字符串也是绝对正确的。

这是一个简单版本的代码

<php

//Take 3 subs at a time 3 home and 3 away players
for($subs = 3;$subs<=$count_subs;$subs+=3){

//Set the answers for each player to 'no' (the for loop sets all players to no).
for($data=0; $data<$squad_length; $data++){
    $input[$data] = 'no';
}

//Select 3 subs home and away for each team, starting from 0 and restrict to 3 and move up by 3's.
$h_subs_name = array_slice($home_subs_name,$subs-3, $subs);
$a_subs_name = array_slice($away_subs_name,$subs-3, $subs);

//Identify the matches from the players in the team squad with the subs 
$subshome = array_intersect($team_squad, $h_subs_name);
$subsaway = array_intersect($team_squad, $a_subs_name);

//if array is not empty run code
if(!empty($subshome)){
//For each match in the change the 'no' to a 'yes' from the forloop.
    foreach ($subshome as $key => $value) {
    # code...

    //Select the index to change to a yes
        $input[$key] = $y;

    }
}

//if array is not empty run code
if(!empty($subsaway)){
//For each match in the change the 'no' to a 'yes' from the forloop.
    foreach ($subsaway as $k => $eachplayer) {
    # code...

//Select the index to change to a yes
        $input[$k] = $y;
    }
}

foreach ($input as $s) {
$inserttablesub[] = '"'. $s . '"';
}

$querysub = 'INSERT INTO '.$subtable.' '.'('. implode(',', $players_name_insert).') '.'VALUES'.'(' . implode(',', $inserttablesub) . ')';

mysql_query($querysub) 
    or die(mysql_error());

unset($subshome);
unset($subsaway);
unset($input);
unset($inserttablesub);
}

?>

team_squad 用作数据库中的列名

Answer 1

一个名为 array_search 的函数，在数组中查找匹配项并返回键号。

$key = array_search($a_subs_name[$c], $team_squad);

这里是文档array_search。

Answer 2

team_squad 和 a_subs_name 应该是变量 $team_squad 和 $a_subs_name

你可以使用in_array()函数

参考：http://in3.php.net/in_array

Answer 3

你为什么不试试array_interset()

这将找到2个数组之间的公共元素，您可以使用该数组进行插入查询'

$team_squad = array("Wojciech Szczesny", "Per Mertesacker","Olivier Giroud","Laurent Koscielny","Bacary Sagna","Mesut Özil","Aaron Ramsey","Kieran Gibbs","Santi Cazorla","Jack Wilshere","Bacary Sagna","Nacho Monreal","Thomas Vermaelen");    

$a_subs_name = array("Carl Jenkinson","Santi Cazorla","Lukas Podolski","Darren Bent","Alexander Kacaniklic","Giorgos Karagounis","Mathieu Flamini","Nacho Monreal","Bacary Sagna");

$result = array_intersect($team_squad, $a_subs_name);
