有条件地运行php代码 [英] Run php code conditionally

问题描述

我想基于php数组返回的值或值来运行代码.如果将值返回为Disabled，则处于禁用状态的商品将不匹配.

I want to run the code on the basis or values returned from php array. If value is returned as disabled , offer with disabled status will not be matched.

这行代码可以正常工作.

This line of code is working fine .

if ($condition1 >= $offer1 AND $condition2 >= $offer2  AND 
$condition3 >= $offer3  AND  $condition4 >= $offer4     ) 
      {  //run code }
else {  //some error messages  }


$condition1 and all are numeric value 
$offer1  and all are numeric value

样本输出和数组值

while($row = mysql_fetch_array($sql))  
{
$offerstatus[] = $row['offer_status'];
//some more output
}

存储在此数组$ offerstatus []中的值=启用或禁用

Values stored in this array $offerstatus[] = enabled or disabled

这些值存储为参考offer
样本值

these values are stored with reference to offer
Sample Values

offer   status 
offer1  enabled
offer2  enabled 
offer3  disable
offern  disable

或

condition     offer status
 50           51    enabled
100           99    enabled
122          865    disable
NNN          offern disable

我想基于从此数组 $ offerstatus [] 返回的值运行上述查询，以便仅匹配那些已启用其值的条件.
问题:
我要为重新调整为enabled的所有值运行此代码，并希望匹配这些条件.

I want to run the above query based on values returned from this array $offerstatus[] .so that only those conditions are matched whose values are enabled.
Question:
I want to run this code for all the values that are retunred as enabled , and want to match those conditions.

基于样本值

以上内容应自动变为

if ($condition1 >= $offer1 AND $condition2 >= $offer2     ) 
      {  //run code }
else {  //some error messages  }

如果问题不清楚，请告诉我.

Please let me know if the question is not well clarified.

推荐答案

条件和要约必须位于数组中

condition and offer must be in array

$condition=array(50,100,122);
$offer=array(51,99,865);

现在过滤那些具有 enabled

function filter_enabled($val){
    if($val=='enabled'){
        return true;
    }
}

$filtered_offerstatus=array_filter($offerstatus,'filter_enabled');

现在$filtered_offerstatus仅包含启用的那些值，现在检查条件是否大于要约

Now $filtered_offerstatus contains only those value which are enabled , now check if condition is greater than equal to offer

$check=false;
foreach($filtered_offerstatus as $key=>$value){

        if($condition[$key]>=$offer[$key]){
            $check=true;
        }
        else{
            $check=false;
            break; //if $condition is less than $offer it will get out of loop.
        }
}

现在，如果所有值均设置为 true ，则将执行该代码，否则将执行错误消息

Now if all value set to true the code will be executed otherwise error message

if($check===true){
    echo "Execute Code";
}
else{
    echo "Some Error Message";
}

注意:我们假设$ condition，$ offer和$ offerstatus具有相同的数组长度，否则该程序将无法工作.

Note: we assume that $condition ,$offer and $offerstatus have the same length of array, otherwise this program will not work.
