In Java, is there an equivalent library for Java’s DisplayTag? -Isthere an equvent library to Java’s DisplayTaginPHP?
For a long time in the Java/JSP world I used to use the Display Tag library to generate a table that would allow you to sort a table, and export the table as a CSV file. In the Java/JSP world, I used to use the display tag library to generate a table that would allow you to sort the table, and export the table as CSV document. Is there anything like this in a PHP library that I could use? Is there such a thing in the PHP library I can use? 4 solutions #1 The answer, from my searching, appears to be no. I wanted one too–love displaytag. From my searches, the answer seems to be no. I also want a – love display tab. If you want a php only solution, Structures_DataGrid seems to be the best solution. Here’s an article about it. This handles paging and sorting, but no exporting. Not sure how supported it is, either.

In java, the subclass calls the parent class construction method, precautions_Subclass calls the parent class construction method_PJlei’s Blog
There is a characteristic of inheritance, that is, subclasses cannot access parent classprivatefield or privatemethod. For example, the Student class cannot accessPersonnameandagefield: class Person { private String name; private int age; } classStudent extends Person { public String hello() { return “Hello, “ + name; // Compile error: cannot accessname Field } } span> This weakens the role of inheritance. In order to allow subclasses to access the fields of the parent class, we need to change private to protected. Fields modified with protected can be accessed by subclasses: class Person { protected String name; protected int age; } classStudent extends Person { public String hello() { return “Hello, “ + name; // OK! } } Therefore,protected Keywords can control the access rights of fields and methods within the inheritance tree, a protected Fields and methods can be accessed by its subclasses and subclasses of subclasses, which we will explain in detail later. 2. The use of super superThe keyword indicates the parent class (super class). When a subclass refers to a field of the parent class, you can use super.fieldName. For example: class Student extends Person { public String hello() { return “Hello, “ + super.name; } } The…
