我嘗試運行一個cron job
對我的數據庫執行備份。Cron作業不運行php代碼
執行cron job
的問題,我收到一封電子郵件,表明cron作業正在執行,但問題是我沒有備份文件。 但是,如果我在瀏覽器上運行的頁面沒有cron job
我有一個備份文件。 另外我有一個按鈕,如果我點擊這個按鈕,我收到一個備份文件。 這意味着我的代碼工作。
cron作業文件:
<?php
include("includes/connect.php");
include("includes/functions.php");
include("includes/backup.php");
?>
備份功能,這功能在functions.php的
<?php
function Export_Database($host,$user,$pass,$name,$tables=false,$backup_name=false)
{
$mysqli = new mysqli($host,$user,$pass,$name);
$mysqli->select_db($name);
$mysqli->query("SET NAMES 'utf8'");
$queryTables = $mysqli->query('SHOW TABLES');
while($row = $queryTables->fetch_row())
{
$target_tables[] = $row[0];
}
if($tables !== false)
{
$target_tables = array_intersect($target_tables, $tables);
}
foreach($target_tables as $table)
{
$result = $mysqli->query('SELECT * FROM '.$table);
$fields_amount = $result->field_count;
$rows_num=$mysqli->affected_rows;
$res = $mysqli->query('SHOW CREATE TABLE '.$table);
$TableMLine = $res->fetch_row();
$content = (!isset($content) ? '' : $content) . "\n\n".$TableMLine[1].";\n\n";
for ($i = 0, $st_counter = 0; $i < $fields_amount; $i++, $st_counter=0)
{
while($row = $result->fetch_row())
{ //when started (and every after 100 command cycle):
if ($st_counter%100 == 0 || $st_counter == 0)
{
$content .= "\nINSERT INTO ".$table." VALUES";
}
$content .= "\n(";
for($j=0; $j<$fields_amount; $j++)
{
$row[$j] = str_replace("\n","\\n", addslashes($row[$j]));
if (isset($row[$j]))
{
$content .= '"'.$row[$j].'"' ;
}
else
{
$content .= '""';
}
if ($j<($fields_amount-1))
{
$content.= ',';
}
}
$content .=")";
//every after 100 command cycle [or at last line] ....p.s. but should be inserted 1 cycle eariler
if ((($st_counter+1)%100==0 && $st_counter!=0) || $st_counter+1==$rows_num)
{
$content .= ";";
}
else
{
$content .= ",";
}
$st_counter=$st_counter+1;
}
} $content .="\n\n\n";
}
$fp = fopen($_SERVER['DOCUMENT_ROOT']."/backup"."/mybackup-".date('d-m-Y')."-".date('H:i:s').".sql","wb");
fwrite($fp,$content);
fclose($fp);
exit();
}?>
備份頁:
<?php
$mysqlUserName = "***";
$mysqlPassword = "";
$mysqlHostName = "****";
$DbName = "****";
$backup_name = "mybackup.sql";
$tables = array();
$showTable = "SHOW TABLES from $DbName";
$getData = mysqli_query($conn, $showTable);
while ($row = mysqli_fetch_row($getData)) {
$tables[] = $row;
}
Export_Database($mysqlHostName,$mysqlUserName,$mysqlPassword,$DbName, $tables=false, $backup_name=false);
?>
我怎樣才能解決這個問題跑cron作業執行時的代碼?? !!
