From: Andres Gonzalez on 24 May 2010 17:16 I have a large C source file that is generated by a separate source-generating program. When the generated src file is compiled, it produces tons of warnings. I want to edit the generated src file and delete the offending lines. What is the easiest way using a PHP script to read in a file, search for a particular signature, and delete a couple of lines? Seems like this would be very easy in PHP. Thanks, -Andres

From: Ryan Sun on 24 May 2010 18:00 yea, file_get_contents and file_put_contents are the easiest, but play with caution when dealing with large files, 'cause it loads the whole file into memory, fopen() fread() fwrite() can be used for large files.
