Question

Is it possible to change while by foreach in mysql_fetch_row in PHP?

For example

$result = mysql_query("SELECT * FROM test");

while ($row = mysql_fetch_row($result)) {
    print_r($row);
}

This will take all records(rows) from query SELECT * FROM test.

But, if foreach is used

foreach (mysql_fetch_row($result) as $row) {
    print_r($row);
}

This will take only first record(row) from query SELECT * FROM test.

Is it possible get all records by foreach loop when using with mysql_fetch_row ?

Answer 1

You can only use foreach if:

• you create a class that implements ArrayAccess or Iterator, or
• you obtain the whole result set in an array and use that array with foreach.

You could use a for loop, but the code would be less than readable:

for ($row = mysql_fetch_row($result); $row !== false; $row = mysql_fetch_row($result)) {
    print_r($row);
}
