The FOREACH below is giving me the error:
Invalid argument supplied for foreach()
Does anyone understand what I have done to cause this error?
#query for words
$query = "
SELECT `reference` , `word` , `explanation`
FROM `Bible_dictionary`
WHERE `live` =1
ORDER BY RAND( )
LIMIT 5
";
$words_match_up_result=mysql_query($query);
$records_found=mysql_numrows($words_match_up_result);
echo $records_found . "<br>"; # output is 5
#create array from mySQL query
$words = array();
$explanations = array();
$i=1;
while ( $i <= $records_found ) {
$words[$i] = stripslashes( mysql_result($words_match_up_result,($i -1),"word") );
$explanations[$i] = stripslashes( mysql_result($words_match_up_result,($i -1),"explanation") );
++$i;
}
#shuffle arrays
$match_words = shuffle ( $words );
$match_explanations = shuffle ( $explanations );
#display words on the screen
foreach($match_words as $word) {
echo $word . "<br />\r\n";
}

Subject: Word Activity Application
I am working on a word activity --- matching words and their definitions.
I want to display 5 words on the left hand side and the 5 definitions on the right hand side. But I want the definitions displayed in a different order than the words so the user submits their answer.
Should I use PHP to display the definitions in random order? OR Is there a way do this in mySQL that would mix and match results from different rows? This is the query gives me the 5 results
SELECT `reference` , `word` , `explanation`
FROM `Bible_dictionary`
WHERE `live` =1
ORDER BY RAND( )
LIMIT 5
