I need to run some PHP scripts in the background, this script should still run while i log off my SSH session. I first try php myscript.php & It run in the background, but then when my SSH ends, the job will be also suspended.

If you want to check if it’s actually runnning, use this commmand jobs -lRead More →

Long time ago, when i design the database, i never think of the character set for my database. But recently, i have to work on some non-english language like Chinese and Korean. I found that my database does not store the info correctly. So here is my suggestion: No matter if you decide to support multiple language or not, when you design your database, you should use UTF-8 as the character set. If you are using mysql and your database is not not with UTF8 – you should use this query to convert it to UTF8. ALTER TABLE table_name CONVERT TO CHARACTER SET utf8 COLLATERead More →

I have a Chinese text file that’s not encoded in UTF8 , it’s encoded with gb2312 . I have been struggling to insert it into mysql. When i copy the text file & import it to mysql via phpmyadmin, it display chinese character very well, but if i use php to insert it, it display some weird characters. It turned out that i need to re-encode gb2312 to ut8 in php before inserting to database. The reason when it’s working fine via phpmyadmin, it’s because when we copy & paste, the browser already re-encode from gb2312 to utf8. here is the function i use: $text=Read More →

When you think your mysql is slow , the first step is to analyze your sql query with “Exlain” command. This is an example explain select * from table1 inner join table2 on table1.field1=table2.field2 and table.field3 =577458498 It will give you some thing like this , look at the “rows” column , if the number of that column is too high, try to reduce it by changing your query , or add index. +——–+——+——————-+———+———+——-+——+———–+ |table | type | possible_keys | key | key_len | ref | rows |Extra | +——–+——+——————-+———+———+——-+——+———–+ |employee| ref | surname,surname_2 | surname | 41 | const | 1 |where used |Read More →

If I’m ever wondering how long my PHP scripts take to execute, I add this code to the start of my pages: <?php function getTime() { $a = explode (‘ ‘,microtime()); return(double) $a[0] + $a[1]; } $Start = getTime(); ?> Then I add this to the end of my script: <?php $End = getTime(); echo “Time taken = “.number_format(($End – $Start),2).” secs”; ?> Sometimes it’s good to get hard figures on how long your script takes to execute, particularly with complex MySQL queries. If your script is particularly tardy and you want to find out where the blockage occurs, you could also try moving the $Start or $End lines to different parts of the script to measure the execution speed of each section.Read More →
