To get the data between two dates in CodeIgniter, you can use the BETWEEN Operator. The BETWEEN operator selects values within a given range. The values can be numbers, text, or dates. More
$this->db->query("SELECT * FROM TABLE WHERE date BETWEEN '$startDate' AND '$endDate'");
Using SQL IN operator with PHP array
Suppose we have a array named ‘id_array’ which contains id’s. Now, in order to get all the records from our MySQL table using this array of id, we can use the below given code :
SELECT * FROM TABLE WHERE id IN (".implode(',',$id_array).")
Here is the full script to create a backup of your MySQL database using PHP :
backup_tables('localhost','username','password','database');
/* backup the db OR just a table */
function backup_tables($host,$user,$pass,$name,$tables = '*'){
$link = mysql_connect($host,$user,$pass);
mysql_select_db($name,$link);
//get all of the tables
if($tables == '*') {
$tables = array();
$result = mysql_query('SHOW TABLES');
while($row = mysql_fetch_row($result)) {
$tables[] = $row[0];
}
}
else {
$tables = is_array($tables) ? $tables : explode(',',$tables);
}
//cycle through
foreach($tables as $table) {
$result = mysql_query('SELECT * FROM '.$table);
$num_fields = mysql_num_fields($result);
$row2 = mysql_fetch_row(mysql_query('SHOW CREATE TABLE '.$table));
$return.= "\n\n".$row2[1].";\n\n";
for ($i = 0; $i < $num_fields; $i++) {
while($row = mysql_fetch_row($result)) {
$return.= 'INSERT INTO '.$table.' VALUES('; for($j=0; $j < $num_fields; $j++) {
$row[$j] = addslashes($row[$j]);
$row[$j] = ereg_replace("\n","\\n",$row[$j]);
if (isset($row[$j])) {
$return.= '"'.$row[$j].'"' ;
}
else {
$return.= '""';
}
if ($j < ($num_fields-1)) {
$return.= ',';
}
}
$return.= ");\n";
}
}
$return.="\n\n\n";
}
//save file
$handle = fopen('db-backup-'.time().'-'.(md5(implode(',',$tables))).'.sql','w+');
fwrite($handle,$return);
fclose($handle);
}
