Troubleshooting Problems Opening PHP4 Files

Frequent PHP4 Opening Issues

MacroMates TextMate is Not Installed

Double-clicking your PHP4 file prompts the message "%%os%% Can't Open PHP4 File". Usually, this is because you do not have MacroMates TextMate for %%os%% installed. Your operating system cannot associate your PHP4 with MacroMates TextMate, so double-clicking the file won't work.

Tip: If you have another software that you know opens PHP4 files, you can select it by hitting the "Show Apps" button.

Outdated MacroMates TextMate

Sometimes your installed version of MacroMates TextMate won't support your PHP 4 Web Page file. Installing the latest version of MacroMates TextMate from MacroMates is recommended. This problem is predominately due to having a PHP 4 Web Page file version that was created by a newer version of MacroMates TextMate than what you have installed on your PC.

Tip: Right-clicking on your PHP4, then clicking "Properties" (Windows) or "Get Info" (Mac), can provide clues about your file version.

Summary: Not having the right MacroMates TextMate version on your computer can cause problems opening PHP4 files.

Additional PHP4 Opening Issues

Although you might already have MacroMates TextMate or another PHP4-associated software installed on your computer, you can still encounter problems opening PHP 4 Web Page files. If you are continuing to have errors with loading PHP4 files, other external issues might be to blame. Problems unrelated to software:

• Corrupt Windows Registry file path references for PHP4
• Mistaken removal of the Windows registry PHP4 description
• Incomplete or bad installation of a software application associated with the PHP4 format
• Your PHP4 file is corrupted (issues with your PHP 4 Web Page file itself)
• Past or present virus infection has affected your PHP4
• Hardware associated with PHP4 has outdated drivers
• Windows cannot load your PHP 4 Web Page file due to insufficient resources (eg. RAM)
