how can we check the indexes of an array in if statement and if it is not available than skip or else perform something. i am using in array function but it is not working and throws an error of undefined offset.
<!DOCTYPE html>
<html>
<head>
<title>csv view</title>
</head>
<body>
<table>
<thead>
<?php
$num_of_rows = count($missing_record_data);
$num_of_columns = count($missing_record_data[$index]);
for($i=0; $i<=$num_of_columns-1; $i++):
?>
<th><?= $column_names[$i]; ?></th>
<?php endfor; ?>
</thead>
<tbody>
<?php for($i=0; $i<=$num_of_rows-1; $i++): ?>
<?php
if(in_array($missing_record_data[$i+1],$missing_record_data)):
?>
<tr>
<?php for($j=0; $j<=$num_of_columns-1; $j++): ?>
<td><?= $missing_record_data[$i+1][$j]; ?></td>
<?php endfor; ?>
</tr>
<?php
endif;
endfor;
?>
</tbody>
</table>
