bash function swallow new line inside a loop

Question

I am new to bash, trying to put together a little helper for myself.

I have a function and it seems it swallow new lines in the inner loop.

#!/bin/bash

collect_results(){
    egrep -o 'public function[ \t][ \t]*[a-zA-Z_]*' $@
}

get_function_name(){
    cut -d' ' -f3 <<< $1
}

get_file(){
    cut -d' ' -f1 <<< $1 | cut -f1 -d":"
}

IFS=$'\n'

RESULTS=( $(collect_results src/Model/Table/*) )

for RESULT in "${RESULTS[@]}"; do
    FUNCTION=$(get_function_name $RESULT)
    if ! [[ "$FUNCTION" =~ ^(beforeFind|buildRules|initialize|validationDefault|'')$ ]]; then
        FILE=$(get_file $RESULT)
        TMP=$(echo $FILE | sed "s/src/tests\/TestCase/")
        TESTFILE=$(echo $TMP | sed "s/\.php/Test\.php/")
        
        echo $TESTFILE
        
        TESTRESULTS=$(collect_results $TESTFILE)

        for TESTRESULT in "${TESTRESULTS[@]}"; do
            echo $TESTRESULT
        done
    fi
done

I get this output:

tests/TestCase/Model/Table/SuggestionsTableTest.php
public function setUp public function tearDown public function testGetSuggestionsOneWord public function testGetSuggestionsMultipleWordsOneMatch public function testGetSuggestionsMultipleWordsMultipleMatches

What I want is to have all the functions in new line, what is exactly what I get in the outer for loop.
