file() function

epp_b

I need to read a file into an array and return the key the array element in which a specific line of the file has been parsed into.
The file() function is supposed to read a file with each line in an array element (http://www.php.net/manual/en/function.file.php)Here's my code:

<?php
$filetoread = file("file.html");

$c = count($readthefile);
$keytofind = array_search("string to find", $filetoread);

echo $keytofind
?>

Assuming that the file it's trying to read (file.html) consists of:

<html>
<body>
string to find
</body>
</html>

It should return "2", am I wrong?

I parse the html files like this:

PHP file:

<?php
$filetoread = file("test.htm");
$c = count($filetoread);
for ($i=0;$i<=$c; $i++) {
if(is_integer(strpos($filetoread[$i], "[FIND]")))
echo $i;

}
?>

Returs line on wich searched fragment was found.

I'm sorry, I should have been more clear in my first post.
I need to read a file up to a point, and then read the rest of the file:

I need to read up until , then read everything after . Should this not work:

<?php
$readthefile = file("file.html");

$c = count($readthefile);
$topkeys = array_search("", $readthefile);
$botkeys = array_search("", $readthefile);

for ($i=0;$i<$topkeys;$i++) {
$top .= $readthefile[$i];
}

for ($i=$botkeys;$i<$c;$i++) {
$bottom .= $readthefile[$i];
}

echo $top;
echo "text to insert between values";
echo $bottom;

?>

Note that I don't want to use a require() or include() function for certain reasons.
