ternary operator in array

Question

I am trying to use the ternary operator in a string in PHP

"hard_copy"=>"<input type='checkbox' (($station->hard_copy==1)?'checked':'') name='station[]' id='hard-copy-$key' class='hard-copy' value='hardcopy-$station->id-1' >
<label for='hard-copy-$key' style='margin-left: 30%;'></label>",

but I am having probably some syntax error

there is no error i am trying to check the checkbox upon condition and checkbox is not getting checked — saad nasim, Sep 02 '21 at 08:09
You can't unpack statements inside double quoted strings like that, only variables. You need to use concatenation. `"foo " . ($a == 1 ? 'checked' : '') . " bar"` — M. Eriksson, Sep 02 '21 at 08:09

If you get an error, always include the error in your question. — Gert B., Sep 02 '21 at 08:15

I Will answer as I understand the question
as @Magnus Eriksson mentioned " You can't unpack statements inside double-quoted strings like that, only variables. You need to use concatenation. "
try this one

"hard_copy"=>
"<input type='checkbox' ". (($station->hard_copy==1) ? 'checked' : '') . "name='station[]' id='hard-copy-$key' class='hard-copy' value='hardcopy-$station->id-1' >
<label for='hard-copy-'".$key." style='margin-left: 30%;'></label>",

Good, but please explain what you've changed, so he can learn from your answer. – Gert B. Sep 02 '21 at 08:16
can you explain why we had to use concatenation for this purpose? – saad nasim Sep 02 '21 at 08:19

Try this using concatenation:

"hard_copy"=> "<input type='checkbox' ". ($station->hard_copy==1 ? 'checked':'' )." name='station[]' id='hard-copy-".$key."' class='hard-copy' value='hardcopy-".$station->id."-1' ><label for='hard-copy-".$key."' style='margin-left: 30%;'></label>",

You also need to add parentheses around the statement: `" . ($station->hard_copy == 1 ? 'checked' : '') . "`. – M. Eriksson Sep 02 '21 at 08:13
