How to get value from next iteration of foreach loop - php

Question

I'm trying to print out entries from a SQL database. Some of the entries are images, and I want to parse those and put them in appropriate HTML markup.
Database Example
id | datatype | typetext
78 | paragraph | "hello"
79 | image | "image.jpg"
80 | paragraph | "goodbye"
The column datatype signifies what type of data is being stored in a given row, and I want to catch when the value of datatype is "image" - then jump to the following typetext column and prepare the appropriate markup for this image.
For instance, some psuedo-code of what I'm trying to do:
if(column is datatype){
if(datatype == 'image'){
echo '<p>' . data inside accompanying typetext column . '</p>';
}
}
Here's my current code:
//the array of the blog entry
foreach($entry as $key => $entryUnit){
//the array of the entry unit
foreach($entryUnit as $column => $cell){
if($column == 'datatype'){
if($key == 'image'){
echo '<br/>';
echo '<p style="color: pink;">' $cell . $entryUnit[$column + 1] . '</p>';
echo '<br/>';
}
}
else if($column == 'typetext'){
echo '<br/>';
echo $cell;
echo '<br/>';
}
}
}
In the first if statement, I try jumping to the next column with echo '<p style="color: pink;">' $cell . $entryUnit[$column + 1] . '</p>';, but this doesn't work.
I've also tried utilizing the next() function, like:
echo '<p>' . next($cell) . '</p>';`
..but this also doesn't work as I thought it would.

Answer 1

You don't need that nested foreach loops, you can everything in just one simple foreach loop.
foreach($entry as $entryUnit){
if($entryUnit['datatype'] == "image"){
echo '<br/>';
echo '<p style="color: pink;">' . $entryUnit['typetext'] . '</p>';
echo '<br/>';
}elseif($entryUnit['datatype'] == "paragraph"){
echo '<br/>';
echo $entryUnit['typetext'];
echo '<br/>';
}
}

Somethink like this should work:
//the array of the blog entry
foreach($entry as $key => $entryUnit){
$i=0;
//the array of the entry unit
foreach($entryUnit as $column => $cell){
if($column == 'datatype'){
if($key == 'image'){
$i++;
echo '<br/>';
echo '<p style="color: pink;">' $cell . $entryUnit[$i] . '</p>';
echo '<br/>';
}
}
else if($column == 'typetext'){
echo '<br/>';
echo $cell;
echo '<br/>';
}
}
}
