Digg stream_get_line
Gets line from stream resource up to a given delimiter
(PHP 5)
Returns a string of up to length bytes read from the file pointed to by handle. Reading ends when length bytes have been read, when the string specified by ending is found (which is not included in the return value), or on EOF (whichever comes first).
If an error occurs, returns This function is nearly identical to fgets() except in that it allows end of line delimiters other than the standard \n, \r, and \r\n, and does not return the delimiter itself. Code Examples / Notes » stream_get_linedante
My testing has found this function to be dramatically faster than fgets on PHP 5.1.14. The difference is probably due to how buffering is used internally. Compare the following: <?php // reads 10,000 lines in 27 seconds while (!feof($handle)) { $line = fgets($handle, 1000000); } ?> vs. <?php // reads 10,000 lines in 0.5 seconds while (!feof($handle)) { $line = stream_get_line($handle, 1000000, "\n"); } ?> 18-apr-2006 10:07
In version 5.0.4 using this funtion and then calling ftell($stream) would give you the position up to but not including the "ending" string. When I rev'd to PHP version 5.1.2, calling this function then using ftell($stream) would give the position up to AND including the "ending" string for example, parsing HTTP responses. The response from apache using curl.... ------------------------------------------------------------ HTTP/1.1 200 OK Date: Tue, 18 Apr 2006 20:54:59 GMT Server: Apache/1.3.33 (Unix) PHP/5.0.4 mod_ssl/2.8.22 OpenSSL/0.9.7e X-Powered-By: PHP/5.0.4 Transfer-Encoding: chunked Content-Type: text/html <html><body>test</body></html> ------------------------------------------------------------- The code: <?php $headers = stream_get_line($in,4096,"\r\n\r\n"); fseek ($in,ftell($in)+4); while (!feof($in)){ fputs ($out,stream_get_line($in,4096,'')); } ?> prior to my 5.0.4 this worked perfectly, trimming the \r\n\r\n section of the HTTP response and seperating the top into the $headers string, and the rest was placed into the file handle $out. using php 5.1.2, the above code chopps off the first 4 bytes of the HTTP response and puts l><body>test</body></html> into $out. |
