Why does mysqlphp only query 100 pieces of data?

Why does mysqlphp only query 100 pieces of data, and the php code is in a rush:

  findAll('type="goods"','id DESC', null,500);                foreach($pindaoArr as $pindao){                ?>id;?>" target="_blank">
  name; ?>  
  

The ListPindao. php file code is as follows:

   
  
If something goes wrong, only 100 pieces of data will be displayed. if there is more data, it will not be displayed. Is there a limit for MYSQL,
  
 
 
Reply to discussion (solution)
I personally think that the code gets too much content and the memory is insufficient. we recommend you modify the php. ini file memory_limit.
 
This is not a host issue. it is tested locally and does not exist.
 
1. there may be only so many data records
This is different from local testing, and the databases on both sides are very likely to be different.
  
2. you are using custom classes and functions. without source code, you cannot know if it is a program problem.
 
I am also confused. Oh, don't worry. use other methods.
