Php 如果第二个数组键等于
我有两个阵列:Php 如果第二个数组键等于,php,arrays,function,compare,exists,Php,Arrays,Function,Compare,Exists,我有两个阵列: $choices = array ( [model] => 3D Modeling / BIM [edb] => Engineering & Design-Build [gse] => Green & Sustainable Energy [ipd] => Integrated Project Design [lc] => Lean Constructi
$choices = array (
[model] => 3D Modeling / BIM
[edb] => Engineering & Design-Build
[gse] => Green & Sustainable Energy
[ipd] => Integrated Project Design
[lc] => Lean Construction
[mt] => Material Supply
[ecs] => Electrical Construction & Service
[fps] => Fire Protection Services
[hms] => HVAC & Mechanical Service
[tsl] => Traffic Signal & Lighting
)
$servicesSelected = array (
[model] => 0
[ipd] => 1
[lc] => 2
[mt] => 3
)
我试图检查是否有任何数组2键等于数组1键,如果该键等于数组2键,则打印数组1中的值。我不完全确定从哪里开始。但在这个例子中,我会附和以下内容,因为它们的基伊存在于比较中
- 三维建模/BIM
- 综合项目设计
- 精益建设
- 物资供应
- 这应该可以做到:
<?php
header('Content-Type:text/plain');
$choices = array (
'model' => ' 3D Modeling / BIM',
'edb' => ' Engineering & Design-Build',
'gse' => ' Green & Sustainable Energy',
'ipd' => ' Integrated Project Design',
'lc' => ' Lean Construction',
'mt' => ' Material Supply',
'ecs' => ' Electrical Construction & Service',
'fps' => ' Fire Protection Services',
'hms' => ' HVAC & Mechanical Service',
'tsl' => ' Traffic Signal & Lighting');
$servicesSelected = array (
'model' => 0,
'ipd' => 1,
'lc' => 2,
'mt' => 3);
$printArray = array_intersect_key($choices , $servicesSelected );
var_export($printArray);
?>
这样做
foreach($servicesSelected as $key2=>$serviceSelected)
foreach($choices as $key1=>$choice)
if($key1==$key2) echo $choice;
一个普通的循环?令人惊叹的!!我走上了正确的道路,使用了其他一些php函数。非常感谢。
foreach($servicesSelected as $key2=>$serviceSelected)
foreach($choices as $key1=>$choice)
if($key1==$key2) echo $choice;
