Change a file with specific line

[sniperscope]

Hi all gurus,

How can i Edit or Delete of a file.

For example: i have an INI file something like below and i want to change it. Great appreciate if any help

 

Name = Example;

Age  = 33;              <--------------------- Want to change this line.

School = University;

Address = Japan;      <--------------------- Want to delete this line.

Phone = 0123-14544521;

And add a new line at the end of file, Replace Phone into PhoneNumber.

 

Regards

You can load the file as an array (one line per element) using file. To delete a line you can just delete its element, and to change a line you can iterate over the array until you find the one you need (if it's a large file then you probably do not want to do this as this kind of searching will run in linear time). You can then join them together.

 

You could also use regular expressions to delete and edit.

i would suggest file() to get the files information into an array...if that was all that was in your file...you would have

<?php

$fileName = 'somefile.ini';
$myInfo = file($fileName);

print_r($myInfo); //prints readable array of file info....eg..

/*
[0] = 'Name = Example;'
[1] = 'Age  = 33;'
[2] = 'School = University;'
[3] = 'Address = Japan;'
[4] = 'Phone = 0123-14544521;'
*/ 

 

 

then to edit the information you just use any applicable series of string functions like preg replace, or strstr...or just flat out replace the array value at what ever point...then to rewrite the data back onto the file just iterate through your array and use the fwrite function... :-)
