How can I use the PHP File api to write raw bytes? |
|php|file-io| |
I want to write a raw byte/byte stream to a position in a file.
This is what I have currently:
<pre>
<code>
$fpr = fopen($out, 'r+');
fseek($fpr, 1); //seek to second byte
fwrite($fpr, 0x63);
fclose($fpr);
</code>
</pre>
This currently writes the actually string value of "99" starting at byte offset 1. ... |
Because it's the name of a builtin function. |
The main advantage is access to the API's and language features not found in PL/SQL. For example, I have used them for regular expression processing, file/directory manipulation and XML parsing.
There are a number of disadvantages:
<ul>
<li>Poor tool support
<li>Lack of control over the JVM

If you are looking simply to see if all lines in FileA are included in FileB you could read it in and just compare streams inside a loop.

If you're using gcc, or any compiler that uses glibc, you can use the backtrace() functions in execinfo.h to print a stacktrace and exit gracefully when you get a segmentation fault. Documentation is here:

How can I make Windows software run as a different user within a script? |

I'm using a build script that calls Wise to create some install files.

The [Display Tag Library][1] is very good at presenting paginated result sets in servlets or portlets. But it normally works with the whole list loaded into memory.

Selenium is good, but kindof slow. Since unit tests should rarely (if ever) go out of process, they should be much faster than your selenium tests.

Your example seems to prove otherwise :-) The hash code for the key `MyClass` and the value `1` is the same for both `KeyValuePair`'s . The KeyValuePair implementation must be using both its `Key` and `Value` for its own hash code
