PHP - loop through SQL resultset. When condition met repeat - php

Question

Pretty new to PHP so here's the question. I have a SQL resultset with the following structure:
ItemID Desc
0 A
1 B
2 C
0 D
3 E
0 F
4 G
5 H
For each ItemID = 0 I want to create a table. Then for each ItemID under ItemID = 0, I want to create a row in a new table, until I hit the next ItemID = 0. Repeat until end.
Desired results:
<table>
<tr>
<td>A</td>
</tr>
</table>
<table>
<tr>
<td>B</td>
</tr>
<tr>
<td>C</td>
</tr>
</table>
<table>
<tr>
<td>D</td>
</tr>
</table>
<table>
<tr>
<td>E</td>
</tr>
</table>
<table>
<tr>
<td>F</td>
</tr>
</table>
<table>
<tr>
<td>G</td>
</tr>
<tr>
<td>H</td>
</tr>
</table>
I can get each table to print when ItemID = 0, but doubt it's the correct method. Here's the php code I have so far:
$legendSql="select ItemID, Desc from ...";
$getLegend=sqlsrv_query($conn, $legendSql);
while( $row = sqlsrv_fetch_array( $getLegend, SQLSRV_FETCH_ASSOC) ) {
if ($row['ItemID'] === '.00') { // when ItemID = 0 create table
print '<table>';
print '<tr>';
print '<td>';
print $row['Desc'];
print '</td>';
print '</tr>';
print '</table>';
}
// foreach( )?????
}

Answer 1

Something like this :
$first=1;
while( $row = sqlsrv_fetch_array( $getLegend, SQLSRV_FETCH_ASSOC) )
{
if ($row['ItemID'] === '.00') // when ItemID = 0 create table
{
if ($first==0)
{
print '</table>';
}
print '<table>';
print '<tr>';
print '<td>';
print $row['Desc'];
print '</td>';
print '</tr>';
print '</table>';
$first=1;
}
else
{
if ($first==1)
{
print '<table>';
$first=0
}
print '<tr>';
print '<td>';
print $row['Desc'];
print '</td>';
print '</tr>';
}
}
if ($first==0)
{
print '</table>';
}

Just change your if statement slightly:
if ($row['ItemID'] === '.00') { // when ItemID = 0 create table
print '<table>';
}
print '<tr>';
print '<td>';
print $row['Desc'];
print '</td>';
print '</tr>';
And outside the while loop, put this:
print '</table>';
The entire loop structure becomes:
while( $row = sqlsrv_fetch_array( $getLegend, SQLSRV_FETCH_ASSOC) ) {
if ($row['ItemID'] === '.00') {
print '<table>';
}
print '<tr>';
print '<td>';
print $row['Desc'];
print '</td>';
print '</tr>';
}
print '</table>';
