fwrite() and php

[zfred09]

Alright say that when a condition is met, an entirely new php file is created with fwrite() and there is no code in it.  How do you automatically write php code into that file using a script?

[url=http://php.net/fwrite]fwrite[/url]().

Yes I know fwrite writes to a file, maybe my question wasn't clear, how do I write php code to that new file, because this method below doesn't work with php, you get unexpected string errors.[code]
$text = "<?php echo("hi dude"); $_SESSION['hello']="Hi"; ?>";
$file = "aaa.php"; 
if (!$my_file = fopen($file,"a")) {
  echo "Unable to open $file";
  }
if (!fwrite($my_file, $text)) {
  echo "Unable to write to $file";
  }
echo "Text entered into $file"; 
fclose($my_file); [/code]

Just remember you need to escape quotes inside a string or use single quotes so this should work:

$text = '<?php echo("hi dude"); $_SESSION["hello"]="Hi"; ?>';

I get string errors in the new file in places such as this because the quote after the echo should be a ' but I had to change it or the write file would error out[code]
echo("<form method="post" action="auth.php"><p>Username:&nbsp<input type="text" name="userid" id="myform" maxlength="20" size="12"/></p>
<p>Password :&nbsp<input type="password" name="userp" id="myform" maxlength="20" size="12"/></p>
<input type="submit" value="Login" class="gobutton"/></font>
</form>");[/code]

Every time you have a " inside a string with a ", you have to escape it. You're still not doing that.
If you want to always use " use this: \"

echo("<form method=\"post\"

[ShogunWarrior]

It won't error and you can keep everything the same as long as:
* You remeber not to include the type of quote (" or ') that surrounds a string in that string without escaping it:
[b]\"[/b] or [b]\'[/b]

Ah yes that works, I didn't understand/know what escaping the quotes was so thanks for the explanation.  Problem Solved.
