After fopen, can I search for a keyword in PHP?

If I use fopen on a file, is there any way to scan through the file to find the number of bytes a certain keyword begins at? If not, how can I do t开发者_Python百科his?

one way,

$data = file_get_contents("file");
print strpos("$data","myword");

The way you phrase this question makes it sound like you're looking for something other than basic string manipulation. If that's what you're saying - nope, string functions are your only option.

Just get the content as you normally would.

$content = fread($file_handle, filesize($filename));
$index = strpos($content, 'keyword');
