PHP Set a value once in a loop - php

Question

I have a php script that checks every Sunday of the week and displays data on that day.
Users can change their value for that day to "Yes" or "No'.
I want to add a possibility that the users can't change their choice after every Thursday at 23:59 before that sunday.
I only want the first Sunday not to be editable.
Since this all is in a loop that shows every Sunday until 11 Sundays in the future. I need to find a way to only do this for the first Sunday.
$datum_gisteren = new datetime('yesterday');
echo '<tr>';
echo '<td bgcolor="#3c741a" style="color:#FFFFFF;"> '.$current_user->first_name.''.' '.''.$current_user->last_name.'</td>
<form action="" method="post">';
for ($i=0; $i<=11; $i++){
$date_modified = $datum_gisteren->modify('next sunday')->format('d-m-y');
$datum = get_the_author_meta( $date_modified, $current_user->ID );
$time = '23:59';
if(date('l') === 'Thursday' && date('H:i') >= $time && $date_modified === '06-09-15') {
echo '<td>
<select class="form-field" id="'.$date_modified.'" name="'.$date_modified.'">
'.(($datum == '1') ? '<option value="1" selected disabled="disabled">Nee</option>' : '').'
'.(($datum == '2') ? '<option value="2" selected disabled="disabled">Ja</option>' : '').'
</select></td>';
}else{
echo '<td>
<select class="form-field" id="'.$date_modified.'" name="'.$date_modified.'">
<option value="1" '.(($datum == '1') ? 'selected' : '').' >Nee</option>
<option value="2" '.(($datum == '2') ? 'selected' : '').' >Ja</option>
</select></td>';
}
}
Most of the work is done (I believe) but as you can see. The $date_modified in the first if-statement is "hardcoded" (06-09-15).
I want this value to be the first next sunday. But since this is in the loop it showed every Sunday for 11 times.
How can I set this Sunday once?
Hope it makes sense!!!

Answer 1

You can keep additional variable for it:
$j = 0;
for ($i=0; $i<=11; $i++){
$date_modified = $datum_gisteren->modify('next sunday')->format('d-m-y');
$datum = get_the_author_meta( $date_modified, $current_user->ID );
$time = '23:59';
if(date('l') === 'Thursday' && date('H:i') >= $time && $j === 0) {
$j++;
echo '<td>
<select class="form-field" id="'.$date_modified.'" name="'.$date_modified.'">
'.(($datum == '1') ? '<option value="1" selected disabled="disabled">Nee</option>' : '').'
'.(($datum == '2') ? '<option value="2" selected disabled="disabled">Ja</option>' : '').'
</select></td>';
}else{
echo '<td>
<select class="form-field" id="'.$date_modified.'" name="'.$date_modified.'">
<option value="1" '.(($datum == '1') ? 'selected' : '').' >Nee</option>
<option value="2" '.(($datum == '2') ? 'selected' : '').' >Ja</option>
</select></td>';
}
}
but will be good to segregate php logic from front.
Thanks.
