Delete line containing word

[mycro]

I am trying to create a simple news system and need a little help.

How would I locate a word or phrase (in this case, the random number) and remove just that line from a file?

Thanks!

You need to read the file in using file() then you need to save the file one line at a time if the line doesn't contain the string.
Use foreach() and strstr().
