How to limit search results while using foreach and while loops - php

Question

The following code works well, but I couldn't find a way to limit the number of results. Any ideas please?
$q = "some keywords for search"; // always escape
$keys = explode( " ",$q );
$query = "SELECT * FROM table WHERE para LIKE '%$q%' ";
foreach($keys as $k)
{
$query .= " OR para LIKE '%$k%'";
}
$result = $mysqli->query($query);
while( $row = $result->fetch_assoc())
{
if ($row != 0) {
$title = $row['title'];
}
}
Any help while be appreciated.
Note: the $q holds the search keywords, and then the code explode it, and search for the keywords in 2 steps:
1- as one sentence using ($q as it is).
2- it searches for each keyword as an array after exploding the $q (here is the part that the "foreach" does).
After that the code loops using "while" to find all results match the search request.

Answer 1

Use LIMIT after completing your query.
Also, if you want to get results sorted by some fields in your table, you could also say " ORDER BY fieldname ASC|DESC"
As follows:
$q = "some keywords for search"; // always escape
$keys = explode( " ",$q );
$query = "SELECT * FROM table WHERE para LIKE '%$q%' ";
foreach($keys as $k)
{
$query .= " OR para LIKE '%$k%'";
}
$query .= " LIMIT 10"; //<<<<<<<<<<<<<<<
$result = $mysqli->query($query);
while( $row = $result->fetch_assoc())
{
if ($row != 0) {
$title = $row['title'];
}

Answer 2

Use LIMIT.
SELECT * FROM table WHERE para LIKE '%$q%' LIMIT 2

Answer 3

You can limit the number of results in your MySQL query, like so:
$query = "SELECT * FROM table WHERE para LIKE '%$q%' LIMIT 5";
this will limit it to 5 results. If you want 10, change it to 10
