I get PHP Warning, then my script doesnt work.

[gamesmad]

I get the error -

[code]Warning: preg_replace(): Delimiter must not be alphanumeric or backslash in /home/gamesm/public_html/freeforums/suspend.php on line 26[/code]

Lines 21 - 26 go like this -

[code]21  $settingscontent = file_get_contents($settingsdir);
22
23  $mode[0] = "$maintenance = 0;";
24  $newmode[0] = "$maintenance = 2;";
25
26  $newsettingscontent = preg_replace($mode, $newmode, $settingscontent);[/code]

Any idea where I am going wrong??  Its stopping my script from working...

I think you need a \ before the $ in your mode strings
[code]
23  $mode[0] = "\$maintenance = 0;";
24  $newmode[0] = "\$maintenance = 2;";
[/code]

If you want to change the actual text "$maintenance" not the variable value of $maintenance

Also, since you are not using any reg expressions, it's best to use str_replace() because it runs faster and uses less resources.

OK, I had a go with str_replace, now there is no error, but it doesnt work.  I have attached the file.

you need to add a \ infront of the $ in your strings, otherwise the script will look for the $maintenance value

[code]
$newsettingscontent = str_replace("\$maintenance = 0;", "\$maintenance = 2;", "$settingscontent");
[/code]

[gamesmad]

Now the file doesnt get edited...  And other ideas nogray, or anyone else??

If using preg_replace:
[code]
$mode[0] = '@'."\$maintenance = 0;".'@';
[/code]

Preg_Replace needs placeholders at the start/end of the pattern.

I still cant get it to work, please can someone help??

try:

[code]21  $settingscontent = file_get_contents($settingsdir);
22
23  $mode[0] = "/\$maintenance = 0;/";
24  $newmode[0] = "\$maintenance = 2;";
25
26  $newsettingscontent = preg_replace($mode, $newmode, $settingscontent);[/code]

you need to quote special regular expression characters, see: http://au3.php.net/manual/en/function.preg-quote.php

[nogray]

in your suspend.php

when you echo the $newsettingscontent, is it the correct string?

I notice you have the function file_put_contents_php4 () but you are not calling it anywhere in the script, so the file won't be edited.

Let me know if this solves the problem.
