[SOLVED] Replace all from this to that. - Flat files

[aQ]

Hello!

 

I am experimenting a little using Flat files now. I have a file that looks something like this:

<?php
// variable
$var = "asdasd";

// array
$array = array("lala", "lalal");
?>

 

How can I replace the $array's content with for example "array("blablabla", "blabla")" without knowing the old value of it?

from my understanding of your question:

 

<?php
// variable
$var = "asdasd";

// array
$array = array("lala", "lalal");
$array[1] = $var;
echo $array;
?>

 

try taht

Uhm, I think I was a little unclear.

 

I want to use fwrite to change the values of the array, and let the variable and such stay the same.

 

Thanks.

still unclear do you want to edit another file in which the array is in that fwrite...

I have a file with a form, the form is posted to replace the values in the file with the array.

I think what you're after is something like:

 

<?php
//$file = file_get_contents('yourfile');
$file = '<?php
// variable
$var = "asdasd";

// array
$array = array("lala", "lalal");
?>';
echo '<textarea rows=10 cols=30>'.$file.'</textarea>';
$array_to_replace = "array";//the name of the array you are wanting to replace
$replace_with = '$'.$array_to_replace.'= array("blabla","blahaha");';//whatever you want to replace with
$file = preg_replace('|\$'.$array_to_replace.'(.*?);|s',$replace_with,$file);
echo '<textarea rows=10 cols=30>'.$file.'</textarea>';
//write new file with $file;
?>

 

As you can see, i tested it with a normal string - but if you use file_get_contents you can read the file into a string anyway, so just modify that bit. And then you'll have to write back to the file.

Hey, that's great. Works exactly as I want!
