can i use multiple foreach?

I have the following arrays and loop conditions. I cannot preview this output.

Wanted Output: (this doesn't answer the code I provided below) 

emp_name1 = captamerica  
emp_name2 like ironman

my php code: 

$filter = array('emp_name1','emp_name2');   
$condition = array('=','like');   
$values = array('captamerica','ironman');   

foreach($filter as $row){
    foreach($condition as $row2){
        foreach($values as $row3){
            echo $row." ".$row2." ".$row3."<br>"; 
        }
    }
 }

You can use multiple foraech. but not to display this kink of output.

you have 3 nested loops, each will loop 2 times, which means than echo statement will be executed 2*2*2=8 times.

to print the tow lines you want you will simply need one for loop statement.

for($i=0;$i<2;$i++)
    echo $filter[$i]." ".$condition[$i]." ".$values[$i]."<br>";

You need to have same element count for each array, which is ok for your data. Here is what you need :

foreach($filter as $k=>$row){
  echo $row." ".$condition[$k]." ".$values[$k]."<br>";
}

As long as you doing it on different arrays you can do multiple foreach. The reason is that php has internal array pointers which need to be manipulated during a foreach. If you do multiple foreach on the same array the internal pointers will be disturbed.

I don't get the output you have cited. What I get is :

emp_name1 = captamerica
emp_name1 = ironman
emp_name1 like captamerica
emp_name1 like ironman
emp_name2 = captamerica
emp_name2 = ironman
emp_name2 like captamerica
emp_name2 like ironman
