php - The unstopable Loop X( -

-

this first code. im trying add new posts wordpress site.
mysql query return 4035 rows have details insert new post.
problem : loop wont ever stop! it reach 4035 row , start on 1st row

things tried make stop:

  1. added - if ($loopstimes > 4400) {break;}
  2. limited mysql query 4050 rows

the weird parts:

  1. when limit mysql query limit 900, works perfectly. loop stops when 900 post added, if add 950, script add 943 posts , give me fatal error "maximum execution time reached". script stops.
  2. i increase "maximum execution time" 300 sec , increase memory 128 256mb, use query without limit , loop wont ever stop.

is code problematic? or server issue?

<?php  $username = "xxxx"; $password = "xxxx"; $hostname = "localhost";   $loopstimes = 0;  //connection database $dbhandle = mysql_connect($hostname, $username, $password)  or die("unable connect mysql");  //select database work $selected = mysql_select_db("xxxx_xxxx",$dbhandle)  or die("could not select examples");  //execute sql query , return records // query names $result = mysql_query("select distinct names_list.* ... limit 4050");  if($result === false) {      die(mysql_error()); // todo: better error handling }  //fetch data database while ($row = mysql_fetch_array($result)) {     $p_name= $row["p_name"];     $category= $row["gcategory"];     $subcategory= $row["subcategory"];     $ase_date= $row["ase_date"];      //fix (') prepare mysql query      $pp_name = $p_name;      $newp_name = str_replace("'","''",$p_name);      //query count results     $minprice = mysql_query("select ... product_p_name = '$newp_name' , order product_price_usd");     $countss = mysql_num_rows($minprice);      if($minprice === false) {          die(mysql_error()); // todo: better error handling     }      $rowm = mysql_fetch_array($minprice);     $minprice = '$'.$rowm["product_price_usd"];      // create post object     $my_post = array(         'post_title' => 'my title...',         'post_status' => 'publish',         'post_author' => 1     );      // insert post database     $post_id = wp_insert_post( $my_post );      // add advanced custom field values     update_field( "field_552fc3f84b43r", $p_name, $post_id );       //regex date keep year     if (preg_match("/20.*/", $ase_date, $matches)) {         $ase_year = $matches[0];     }      //insert tags custom taxonomies      wp_set_post_terms( $post_id, $audio_subcategory, 'subcategory-cpt', false );     wp_set_post_terms( $post_id, $fex_pro_rg, 'fex-pro-cpt', false );      $loopstimes++;      if ($loopstimes > 4400) {break;}     echo 'post added!, '.$post_id.'<br>';     echo $loopstimes; }  //close connection mysql_close($dbhandle); echo 'finish'; ?>

sure know shouldn't use mysql_* functions anymore.

but pass on issue right now:

//query count results $minprice_query_result = mysql_query("select ... product_p_name = '$newp_name' , order product_price_usd"); $countss = mysql_num_rows($minprice_query_result);  if($minprice_query_result === false) {      die(mysql_error()); // todo: better error handling }  $rowm = mysql_fetch_array($minprice_query_result); $minprice = '$'.$rowm["product_price_usd"];  mysql_free_result ( $minprice_query_result );

and way, why need subquery? $minprice = '$'.$rowm["product_price_usd"]; ? never use variable in code!

java - UML - How would you draw a try catch in a sequence diagram? -

is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
