Integrated Development Environment or IDE in short . I am some what an active user in the php classes group . Recently an editor was the talk . He actually was looking for a debugger , and many people came with different solutions . I have tried Netbeans , Eclipse, Aptana and Zend Studio . Just installed and run some samples that's all what I have an experince with IDE for PHP. These IDE's are used by php developer , download and try. Many PHP IDE's like Netbeans , Eclipse , Aptana etc are free php developer softwares. Some commercial php developer softwares are also available.
