Edit a file

[rupam_jaiswal]

Hi,
Please excuse if similar query has been posted earlier.

I have text file in which I have to search a word and replace it with a new word.

First I do is get the fopen the file,then read the contents , maintain a string $newcontent that holds the contents of file ,the moment i get my word,replace it with new word in the string $newcontent
After that I write the whole string $newcontent to file again.
What I want is to just while scanning the file,the moment I find my word,replace it with new word there only instead of rewriting the whole file again.
Regards

basically, you cannot do this. you must rewrite the file.

my stock answer to this type of post is this: don't use flat files as a database, use a database as a database. you will have much more precise control of reading/writing/searching/sorting your data if it is in a database rather a flat file.

And the "oh I dont have any DBMS installed/allowed/etc." excuse doesn't fly any more; SQLite doesn't require any server-side software to implement SQL into your apps.
