Comparison of words from the database and output of the result - php

Question

I need to check the words received from the database with the user's entered word and if there is a match, then output its value from the database, and if not, then output what the user entered.
The code below works fine if there is a match.
function d_typeplace_morf($d_typeplace)
{
global $wpdb;
$typeplace_results = $wpdb->get_results('SELECT vozmozhnyi_variant_mesta, ego_slovoforma_v_predlozhnom_padezhe FROM dEzpra_jet_cct_tip_mest_obrabotki');
if ($typeplace_results) {
foreach ($typeplace_results as $typeplace_result) {
$d_typeplace_raw = mb_strtolower($typeplace_result->vozmozhnyi_variant_mesta);
$d_typeplace_morf = mb_strtolower($typeplace_result->ego_slovoforma_v_predlozhnom_padezhe);
$d_typeplace = mb_strtolower($d_typeplace);
if (stripos($d_typeplace, $d_typeplace_raw) !== false) {
echo $d_typeplace_morf;
}
}
}
}
I'm an amateur in PHP, just learning. And I can't figure out how to output $d_typeplace if no match is found.
I tried to add
else {
echo $d_typeplace;
}
, but I get an array of words from the user entered.
I will be grateful for any help. Also for any suggestions for improving this code.
---Addition---
I apologize for my English. This is a problem in the Russian language, I need to take into account the morphology. To do this, the database has a list of words and their analog, for example, X = Y. I get these words and compare what the user entered. If he entered X, then we output Y. If he led Z, which is not in the database, then we output Z.
Thus, we check $d_typeplace with $d_typeplace_raw and if there is a match, we output $d_typeplace_morf, which is equal to $d_typeplace_raw. And if not, then $d_typeplace (it contains the value that the user entered).
Oh, I'm sorry, I understand myself that I'm explaining stupidly)

Answer 1

I cannot quite understand what you are asking: you need to output the string entered by the user, but you can only print an array?
If this is the case, I think you parsed the string before, in order to therefore you need to do join again the values contained in the array.
Try with:
else {
echo implode(" ", $d_typeplace);
}
--- EDITED ---
Try with:
function d_typeplace_morf($d_typeplace)
{
global $wpdb;
$typeplace_results = $wpdb->get_results('SELECT vozmozhnyi_variant_mesta, ego_slovoforma_v_predlozhnom_padezhe FROM dEzpra_jet_cct_tip_mest_obrabotki');
if ($typeplace_results) {
$found = false;
foreach ($typeplace_results as $typeplace_result) {
$d_typeplace_raw = mb_strtolower($typeplace_result->vozmozhnyi_variant_mesta);
$d_typeplace_morf = mb_strtolower($typeplace_result->ego_slovoforma_v_predlozhnom_padezhe);
$d_typeplace = mb_strtolower($d_typeplace);
if (stripos($d_typeplace, $d_typeplace_raw) !== false) {
echo $d_typeplace_morf;
$found = true;
break;
}
}
if (!$found) {
echo $d_typeplace;
}
}
}
But I think it would be more efficient, if you implemented the second code snippet written by #Luke.T

Answer 2

I'm presuming you were trying to add the else like this?
function d_typeplace_morf($d_typeplace)
{
global $wpdb;
$typeplace_results = $wpdb->get_results('SELECT vozmozhnyi_variant_mesta, ego_slovoforma_v_predlozhnom_padezhe FROM dEzpra_jet_cct_tip_mest_obrabotki');
if ($typeplace_results) {
foreach ($typeplace_results as $typeplace_result) {
$d_typeplace_raw = mb_strtolower($typeplace_result->vozmozhnyi_variant_mesta);
$d_typeplace_morf = mb_strtolower($typeplace_result->ego_slovoforma_v_predlozhnom_padezhe);
$d_typeplace = mb_strtolower($d_typeplace);
if (stripos($d_typeplace, $d_typeplace_raw) !== false) {
echo $d_typeplace_morf;
} else {
echo $d_typeplace;
}
}
}
}
Which was outputting an array because the for loop was continuing, if you add a break like so...
echo $d_typeplace;
break;
It should stop outputting an array. Depending on your use case you could however perform similar functionality directly in your sql query using LIKE ...
function d_typeplace_morf($d_typeplace)
{
global $wpdb;
$typeplace_results = $wpdb->get_results('
SELECT ego_slovoforma_v_predlozhnom_padezhe
FROM dEzpra_jet_cct_tip_mest_obrabotki
WHERE vozmozhnyi_variant_mesta LIKE %' . $d_typeplace . '%');
if ($typeplace_results) {
//Echo result
} else {
echo $d_typeplace;
}
}
