Section 10 - Working with Files
July 08, 2012 10:31PM
I have worked through this, it is a good idea to re look at while loops and explode() function before doing the section. Will make it easier to understand. Also if you are having problems writing to the text file check folder permissions, id not set to read/write you will get an error smiling smiley

Completed. Found some of the navigation links are wrong. (php10p2 & php10p3 navigation links send you to section 13).

Language: PHP
<?php
 
$fhandle = fopen("testFile.txt", "a");
$fcontents = "did it change?";
 
file_put_contents($fhandle, $fcontents);
fclose($fhandle);
print "file created and written to";
 
?>

so this is my script, the file is already created. If I use fwrite() it works fine, if I run the script above it gives me the error:
"Warning: file_put_contents() expects parameter 1 to be a valid path, resource given in C:\Program Files\EasyPHP-12.0\www\excersises\TestwriteToFile.php on line 6"

google doesn't seem to have an answer. I think its something to do with the handle but I don't know what exactly, anyone know what I'm doing wrong?

The error says it - invalid path of the handle, therefore is testFile.txt in the same directory as the TestWriteToFile.php?

Yes it is Mac. What would the error be if I didnt have php5? probably a syntax error? I've reloaded everything onto the testing server again but still does the same.

Alrighty, I dont know if anyone else had the same issue. I finaly found the answer, which also worked with my script. in the previous script the $fhandle had a value of fopen(...), apparently the file_put_content(param1,param2,optional param) must have param1 specify the file itself and not the handle. So I changed my script to: 
Language: PHP
<?php
 
$fhandle = "testFile.txt"; //file to be edited
$fcontents = "Lets hope it works"; //contents to be added
 
$path = realpath("testFile.txt"); //test text file path
echo $path."<br>";
 
$file = realpath("TestwriteToFile.php"); //test php page path
echo $file."<br>";
 
file_put_contents($fhandle, $fcontents);
echo "file created and written to";
 
?>

and it worked. param3 then should specify FILE_USE_INCLUDE_PATH, FILE_APPEND or LOCK_EX. if param3 is not specified then everything is erased and only the new content is placed in the file.

Although it worked, is this correct Mac?

No, that is not it. It would make the script not very useful, because you cannot always "hard code" the file name in, e.g. if you have a form that uploads the file, you assign it a handle to manage the name of the file.

Difficult to say because each server set-up is different e.g if xampp installed under program files on win 7 (it should be under C: ) then there can be permission problems. Not that this is your issue. Your first code runs fine with me.

I tried to open a pdf file, well it did open the file but the contents were converted into numbers and some funny characters...is there a function to handle pdf files?

Some pretty cool stuff, saves one time, considering how easy it is to create arrays using the explode function and printing it out on separate lines. Also the ability to open and create documents on the fly.
