How to prevent php foreach loop execute 2nd if statement when 1st if statement is executed?-CodePudding

<?php
foreach($abc as $row)
{
    $msg = "";
    if($row < 100 && $msg=="")
    {
        $msg="Dog";
    }
    
    if($row < 100 && $msg!="")
    {
        $msg="Cat";
    }
}
echo $msg;
?>

Let say it loop 3 data, the output is :

Cat Dog
Cat Dog
Cat Dog

How to make the output become :

Dog
Cat
Cat

I try to add flag to the code but still it is not working:

foreach($abc as $row)
{
    $msg = "";
    $flag=0;
    if($row < 100 && $msg=="" && $flag==0)
    {
        $msg="Dog";
        $flag=1;
    }
    
    if(row < 100 && $msg!="" && $flag==0)
    {
        $msg="Cat";
        $flag=1;
    }
}

CodePudding user response：

Rather than a second if statement, you could use elseif.

elseif($row < 100 && $msg!="")

CodePudding user response：

One problem is with your flow. Within your loop you are setting $msg="", then checking whether it is blank and setting $msg="Dog", then checking that $msg is not blank (which it is not, because you just set it to be "dog") and setting $msg="Cat". It will always flow through those 3 steps.

More clarification might be needed on how you determine whether to output "dog" or "cat".

Try the following:

<?php
foreach($abc as $row)
{
    $msg = "";
    if($row < 100 && $msg=="")
    {
        $msg="Dog";
        break;
    }
    
    if($row < 100 && $msg!="")
    {
        $msg="Cat";
        break;
    }
}
echo $msg;
?>
