RE: [PHP] Searching for text in a file

[Kelly Barrett]

Hi Richard,
First, I think it should be:
$variable = "[EMAIL PROTECTED]";
instead of:
> $line_text= "[EMAIL PROTECTED]";

as you overwrite $line_text with your fgets.

Also:
> if ($variable = trim($line_text)) {
Should be:
 if ($variable == trim($line_text)) {

Otherwise you are doing an assignment, which will always be true.

Finally, your while loop should probably be:
while(feof($fd) == false) {
$line_text = fgets($fd, 2048);

Because fgets returns EOF at the end of a file, not necessarily false (I
THINK EOF currently is false, though theoretically EOF could change to any
value).

Cheers,
Kelly.

You are assigning here - use == for comparison.
