问题 I have a group of about 3,000 folders named XYZ-1 through XYZ-3000. Inside those folders are groups of image files and a description text file. Such as: Property123_0001.jpg Property123_0002.jpg Property123_0003.jpg ... Property123_0085.jpg Property123_0086.jpg Z_Description.txt The number of .jpg files differs in each folder, but there's always a single description file. Each directory's image files have a different name, for example `XYZ-1 might contain Property123, while XYZ-10 might

问题 My use case: I have multiple scripts inserting into a table in the order of several inserts per second. I am seeing performance degradation, so I think there would be performance benefits in "batching queries" and inserting several hundred rows every minute or so. Question: How would I go about doing this using mysqli? My current code uses a wrapper (pastebin), and looks like: $array = array();\\BIG ARRAY OF VALUES (more than 100k rows worth) foreach($array AS $key => $value){ $db -> q(

问题 I am generating a table using the result of mysql query with checkboxes and radio buttons in each row like: while($row4 = mysql_fetch_array($q4)) { $pids = $row4['pid']; echo "<tr>"; echo "<td><input type='checkbox' name='pids[]' class='persistentChecks' style='display:inline-block;cursor:pointer;' value=".$pids."></td>"; echo "<td style='text-align:center;font-size:12px;'>".$counter17."</td>"; echo "<td style='text-align:center;font-size:12px;'>".$row4['cname']."</td>"; echo "<td style='text

问题 think I'm getting things confused here.

I have another loop that is looking in the xml code for each of these files and searching for a particular pattern using findstr and parsing out the Name from some tags

问题 I've found a solution that claims to do one folder, but I have a deep folder hierarchy of sheet music that I'd like to batch convert from png to pdf. What do my solutions look like? I will run into a further problem down the line, which may complicate things. Maybe I should write a script? (I'm a total n00b fyi) The "further problem" is that some of my sheet music spans more than one page, so if the script can parse filenames that include "1of2" and "2of2" to be turned into a single pdf, that

问题 I am trying to insert multiple records using single MySQL query, but i don't want to insert a huge number of records at once. The following code fetches, buildes and inserts the records if(is_array($id_rec)){ $values = ""; foreach($id_rec as $key=>$value){ $values .= "(".(int)$value.",".(int)$id_group."), "; } $values = rtrim($values,", "); $sql = "INSERT IGNORE INTO fu_rec_group_link (id_rec, id_group) VALUES ".$values; $GLOBALS['db']->execute($sql); I have two questions here.
