How I can simplify this PHP code? too many switch() function - php

Question

I made listview in jQuery Mobile and I used PHP to feed its contents. It works properly, but the code is too long and most part of it are very similar to each other. Is there any way to simplify the code? Please have a look at the code, then I'll explain what I really need to do:
<ol data-role="listview">
<?php
while ($row = mysql_fetch_array($result)){
echo "<li><a href=\"#\">";
// first column check
switch ($row[1]) {
case "Behnam":
echo " B . ";
break;
case "Tarin":
echo " T . ";
break;
}
// second column check
switch ($row[2]) {
case "Behnam":
echo " B . ";
break;
case "Tarin":
echo " T . ";
break;
default:
echo " N . ";
}
// third column check
switch ($row[3]) {
case "Behnam":
echo " B . ";
break;
case "Tarin":
echo " T . ";
break;
default:
echo " N . ";
}
// fourth column check
switch ($row[4]) {
case "Behnam":
echo " B . ";
break;
case "Tarin":
echo " T . ";
break;
default:
echo " N . ";
}
// fifth column check
switch ($row[5]) {
case "Behnam":
echo " B . ";
break;
case "Tarin":
echo " T . ";
break;
default:
echo " N . ";
}
// sixth column check
switch ($row[6]) {
case "Behnam":
echo " B ";
break;
case "Tarin":
echo " T ";
break;
default:
echo " N ";
}
echo "</li></a>";
}
?>
</a></li>
</ol>
and the result is:
By using while ($row = mysql_fetch_array($result)){ I can fetch each row of the sql table one by one. But I also need to check the value of each cell(column) as well.

Answer 1

Group the code in a 2 parameter function:
function checkRowValue($row, $checkDefault) {
switch ($row) {
case "Behnam":
echo " B . ";
break;
case "Tarin":
echo " T . ";
break;
default:
if ($checkDefault)
echo " N . ";
}
}
Invoke as:
<ol data-role="listview">
<?php
while ($row = mysql_fetch_array($result)){
echo "<li><a href=\"#\">";
// first column check
for ($i = 0; $i < 7; $i++)
checkRowValue($row[i], $i > 0);
}

Answer 2

This generalizes it by applying a function over all the columns in your row (skipping first) and then string them together with " . ".
while ($row = mysql_fetch_array($result, MYSQL_NUM)) {
echo "<li><a href=\"#\">";
echo join(' . ', array_map(function($v) {
if ($v == 'Behnam') {
return 'B';
elseif ($v == 'Tarin') {
return 'T';
else {
return 'N';
}
}, array_slice($row, 1));
echo "</li></a>";
}

Answer 3

Try This
if(in_array("Behnam",$row) {
echo " B . ";
}
else if(in_array("Train",$row) {
echo " T . ";
}
else {
echo " N . ";
}

This is the final result:
<ul id="competition_list" data-role="listview" data-inset="true" data-theme="a">
<?php
// using the returned value from database to feed the list.
// showing the competiton rounds' outcome.
while ($row = mysql_fetch_array($result)){
echo "<li><a href=\"#\">";
echo $row[0] . "."; //this is the id column in the table and will give me the number of the row
for($i = 1; $i <= 5; $i++){
switch ($row[$i]) {
case "Behnam":
echo " B ";
break;
case "Tarin":
echo " T ";
break;
}
} // end for()
echo "</a></li>";
} // end while()
?>
</ul>

Answer 5

<?php
while ($row = mysql_fetch_array($result)){
echo "<li><a href=\"#\">";
// first column check
foreach($row as r)
{
switch (r) {
case "Behnam":
echo " B . ";
break;
case "Tarin":
echo " T . ";
break;
}
}
?>
