Writing to a file. (PHP)

[Nasimov]

It's possible to ammend data within a file vs. just adding data to the beginning or the end of the file? Mean to change something in the "middle" of the file.
Thanks.

How about:

Read all of the file into a variable

Do a search to insert the new data into the middle of the variable

Write variable back to file


I hope this helps,

Bob

Here:

<?php
$fileContent = implode("", file("filename"));
//Replace a string
$fileContent = str_replace($old, $new, $fileContent);
//OR you can insert/delete a string at a specific point
//in the variable, do whatever processing you need.
$fp = fopen("filename", "w");
fputs($fp, $fileContent);
fclose($fp);
?>

If you want to add something to the end of a file:

<?php
$fp = fopen("filename", "a");
fputs($fp, "Whatever text");
fclose($fp);
?>

At the start of a file:

<?php
$fileContent = implode("", file("filename"));
$fileContent = "New Text" . $fileContent;
//Then just write to file using "w"
?>

HTH,
