php4

Hello All, I have a script that uses the command line and gets user input, then uses exec() to query a texis database. It has about 1400 lines of code and runs as solid as a rock on php3. On php4 it runs now that functions return "" instead of false, but the output hangs from time to time. I am going to try to find exactly what is causing this, but I can say one thing for sure, php4 does not *seem* to be as stable as php3.0.6. I am using lots of ereg_replace() explode() and large arrays of strings in this code. The reason we are using php on the command line, is because the database started as mysql, and there is a web version so a lot of functions that handled building the select statement where simply copied and pasted. -Buddy
