[PHP] Spaces in filename or path
Does it matter to PHP filesystem functions if a path/to/file/name contains spaces? IOW, is this handled OK by design or should I replaces such spaces by backslash-space or would doing that present problems?

I will be passing such paths/names to shell scripts too, but AIUI I can use escapeshellarg () there. As long as PHP filesystem functions don't have a problem then I should be OK.

Here's the URL of the relevant manual page:
http://www.php.net/manual/en/function.pg-fetch-result.php
The manual page did not explain the purpose of the text 'die', so was
ignored (;)).
What, you mean this?
$db = pg_connect(dbname=users user=me) || die();
It's what I would call an ugly and unreadable way of handing errors. Personally
I'd do this:
$db = pg_connect(dbname=users user=me);
if ($db===false)
{
// Do any error handling (such as writing to my log file) here
die ();
}
And which manual page are you talking about? die() is a function so it's
trivial to search for it in the functions list using the search facility on all
PHP documentation pages.
Anyway, the php code was amended as follows:
?php
$db = pg_connect('dbname=databasename user=httpd');
$query = pg_query($db,'SELECT * FROM databasetable');
$value=pg_fetch_result($query,100,0);
echo 'list of files' ,$value,'\n';
?
The result is a web page which shows:
list of files12345\n
where '12345' corresponds correctly to an equivalent value in row 100
of the database table. However, the query requests the entire table.
The php code was then amended as follows, which produces output from
the database:
?php
$db = pg_connect('dbname=databasename user=httpd');
$query = pg_query($db,'SELECT * FROM databasetable');
$value=pg_fetch_all_columns($query,1);
var_dump($value);
?
My personal recommendation, however, is to drop old-style procedural
drivers and switch to PDO - it's much more convenient to use, IMO. If
you use PDO, you don't need to study the API of various different DB
drivers, and your code can easily switch from one database to another.
What does PDO mean, so the relevant parts of the manual can be
reviewed? Thank you.
Go to the PHP Manual front page, scroll down to Database Extensions under
Function Reference.
I think you need to learn to find stuff for yourself in the manual. Finding
PDO, die(), and pg_query (which you initially missed altogether) should be easy
enough.

[PHP] Error recovery - fatal errors
I would like, in my app, to recover from as many run-time errors as possible, so that I can tidy up. And unsolicited output generated by the standard error system is really unhelpful as it becomes part of the ajax reply to the browser. So I've added my own error handler, but it seems that I can't catch fatal errors. The error in question comes from doing something like: $res = $dbh-query ($sql); with $sql being an SQL statement, and $dbh being a database handle. I recently had a case where $dbh was NULL, which triggers a fatal error from SQLite. In principle such a bug should show up quickly, but this one had lain untriggered for about a year. It seems to me somewhat arbitrary for this to be designated a fatal error. Is there a way I can catch these? Most SQLite error situations I'm solving with try/catch but no luck with this one so far. Error handling in library packages seems somewhat arbitrary - e.g. opendir may give an E_WARNING, but closedir, readdir don't. tim -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

The error in question comes from doing something like: Fatal errors are fatal - if you could recover from them, they wouldn't be fatal. Except that this error is arbitrarily designated as fatal when it need not be. A few days ago I discovered register_shutdown_function as mentioned by someone today, and use that to pass E_ERRORs on to my error handler (as declared by set_error_handler). That way I can log the error properly and notify the user in a consistent manner. I've tested this by introducing some errors (e.g. unitialised variables or setting $dbh to null) and these are all nicely picked up. $res = $dbh-query ($sql); with $sql being an SQL statement, and $dbh being a database handle. I recently had a case where $dbh was NULL, which triggers a fatal error from SQLite. In principle such a bug should show up quickly, but this one had lain untriggered for about a year.

You've got something wrong: either $dbh is not null or the error is not from sqlite. I'm guessing the former. To avoid situations like that, do proper error checking (i.e. actually check that your database connection was opened succesfully). No, $dbh was unitialised. It was a coding error where I was using $dbhs instead of $dbh. Since what I was apparently trying to do last year was wrong anyway I've rejigged that section. And obviously I do check that the db is opened; just that in this instance I was using the wrong variable. Error handling in library packages seems somewhat arbitrary - e.g. opendir may give an E_WARNING, but closedir, readdir don't. You can avoid all problems with error output by turning off error displays in php.ini (set display_errors = off) - use error logging instead. That's the recommended setting for production servers. This is not a browser/webserver situation in the classic manner. In this case, the browser, PHP code, and the instance of apache used are all running on the user's machine. The user just thinks they are running a local application. Cheers -- tim -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I have done a print_r and var_dump and nothing is there. My question was if the call ever worked. But you don't know that nothing is there because you haven't looked for the output. When an ajax call is made, it causes a script on the server to be run. You tell the ajax call what script you want to have run, in this case apparently jq_test.php. All output from that script will be returned to the function you specify in the ajax call. As I said, I don't know jquery, but I'm guessing that that is the success: function - and in that you do nothing with the returned results. I should also point out that *all* output from the script will be returned there. That means anything from an echo or var_dump statement, but also anything *outside* ?php and ?, which means all the html that is in your file jq_test.php too. It's all concatenated together as one humungous text string and returned to your ajax success: function. And because you're not looking at those results, you won't see them. 3) Where *are* you expecting the output from var_dump($_POST); to appear, and why? As I understand, $.post [which is an Ajax call??] should put the results into $_POST in the URL: in the call. Well, it might put it into $_POST[move_from], possibly, but I don't know what the JavaScript behind this jquery call actually does. 5) For a simple but effective ajax example, see http://www.clothears.org.uk. Looks good. Thanks but have you understood it? 6) If you're attaching an onclick to each table cell, the onclick handler can write the cell's id into the form, seems to me. Why use ajax for that? Please tell me how to do that [write cell's id into form]. Something like (e.g.): Move From: input type=text name=move_from id=xyz/input and then in your onclick handler: document.getElementById(xyz).textContent = this.id; I'd say also that you need to keep separate your HTML page (where you display your 8x8 grid and click on the cells) from any PHP scripts you want to run with ajax. -- Cheers -- Tim -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

In the former case you get $info[extension]=, in the latter there is no [extension] element in the returned array. OK, this makes sense.

In the interest of clarity and maintainability I would like to be able

So add the appropriate comments to your functions.
This is what I tried:
function integer int_func(string $s) {
// does something like, say, converting five to 5
}
There are two problems:
1 The appearance of a type name before the function name is treated as
a syntax error
2 Even if I forget about declaring the return type and code it instead
as
function int_func(string $s) {
...
}
I get a run-time error when I call the function with a string. (eg
$var = int_func(five);) The error message saysCatchable fatal
error: Argument 1 passed to int_func() must be an instance of string,
string given.
Why are you doing this when the documentation clearly states that this is not
how it works. Did you not read up about it first?
It seems that basic data types cannot be specified in ths way although
(intstances of) classes can. I have successfully used the technique to
catch run-time errors of wrong object types when testing, but am
surprised that I can't use it to trap unexpected basic types - or at
least to document what is expected.
This is PHP, not FORTRAN IV.
Personally I see it as a great step forward that for the most part, I don't
have to bother.

This is certain to fail. You've got the $num++ in the *inner* loop, and are
checking its value in the *outer* loop. Think about it: suppose you enter the
inner loop with $num being 9998. Suppose also that you then go round the inner
loop 5 times. What is the value of $num when you then exit the inner loop in
order to do the test against 1 in the outer loop?
You need to rework that logic.

If you mean use php to interrogate a port I would think the answer is

Computer port=client; PHP=server.
You can if the port is a server port, i.e. you're creating a daemon.. But, if
it is the client machine you wish to inspect, then as Jim mentioned, PHP is
not for you and something like java may be better suited, although I'm not

Er, Try It And See A couple of minutes experimentation might have saved you the time of email, wait for an answer ... Well, there is an sqlite3 executable that one can run to do CLI things to a database. OS X comes with that and I was also able to download the source of that program, and the SQLite C amalgamation, and rebuild it myself. It is certainly possible, with that program, to execute a sequence of semi-colon separated statements. It *doesn't* work with PHP's PDO interface to sqlite, as I found in a test program I put together; I haven't properly tested that with the sqlite3 interface. I've tried asking on the sqlite general mailing list and (to me at least), the answers are at best unclear. There is a function, part of the C interface to sqlite, that talks about a sequence of statements, but I guess ultimately it depends on how the writer of the PHP sqlite3 interface implemented it. -- Cheers -- Tim -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

while I was thinking my scripts didn't have globals, it was a surprise to me

So, if you want a main script variable (i.e., $myVar) to be accessed by a

myFunction

Tim:
I see what you are saying, but the reason for that $myVar declared within the
function is local to that function and will not change the value of $myVar in
the main script -- as such, illustrating differences in scope.
Yes.
But the reason for my post was to illustrate that IF one declares a variable
in the main script THEN that variable will also be automagically included in
the $GLOBAL array.
In short, you cannot write a script without having a $GLOBAL array that
contains every variable you create in the main script -- that is what I found
surprising. YSMV (Your Surprise May Vary).
I suppose my reaction is more like hmmm, interesting. I use globals here and
there, e.g. to keep argument lists from getting very long. But I never use the
$GLOBAL array.

I have a clear idea about *that*. I want to figure out if it's possible to use web sockets with a small server written in PHP to replace my current structure of ajax + apache + processes (which I suppose it forks). I see these benefits: 1) possible benefit - presumably when an ajax request arrives, a new process is started and so PHP has to be loaded and initialised each time. But perhaps this is in some way optimised so the PHP process is left running and apache then just tells it to read/execute a new script. 2) Definite benefit - when a browser makes an ajax request to run a script, it gets no information back until the script completes. Then it gets all of it. I have a couple of unsatisfactory workarounds for that in my existing structure. Websockets appears to offer a way for the browser to receive timely information. 3) understand design patterns I don't know what this means. What your asking is practically impossible in any programming language akin to 'how to un-import packages in Java' or 'how to un-using namespace in C#'. If you don't want to use it, don't include it ;) I do want to use it but would like to be able to replace it with a newer version. If there is no way to do this then that is a data point. And here's another question. Can a child forked by pcntl_fork() use a socket that the parent obtained?

I'm looking for confirmation that: include $fn; is an allowed form of the include statement. While it's certainly possible to rig up something using sockets, I don't think that's how AJAX works, and you'd need a JS library that did. Hmmm, I think perhaps I've not made myself clear - sorry about that. At present I'm using AJAX and apache; I'd like to *stop* doing that (and not use another web server, either). In my case, client and server are the same machine - the user's machine. There is a browser window and JavaScript within it which makes the AJAX requests. I just happen to use apache to have a variety of PHP scripts run to provide results back to the browser window. Generally, you should only really need to dynamically replace parts of a long-running program if you don't want to restart it. However, php scripts are not long-running programs in general, unlike the apache server itself, for example, and certainly if the php scripts are running under apache, they will be time- and space-limited by whatever is set in the php.ini file. If these little scripts are merely responding to AJAX requests, they should be really short-lived. At present these scripts generally are short-lived, but with some notable exceptions.

Plus, the use of @ here leaves a nasty taste in the mouth (as it does in most cases). Instead, I suggest creating a php.ini file and changing this setting there by setting it to a specific time zone. For example, in mine, I have this line: date.timezone = 'America/Phoenix' As I hinted in my previous mail, client and server side of my app are always on the user's machine. When the user starts the app, I create an apache config file on the fly and run an instance of apache just for the user. So I'm not messing with the standard OS X Web Sharing. For the same reason, I don't want to start modifying or creating a php.ini file. This ensures that PHP is always using the same zone no matter what script is running, avoids PHP errors if you forget to make the change in a script, avoids you having to modify all your scripts in the first place, and lets you easily change the time zone used by your applications to whatever you want independently of the server's own time zone (or in 5.4, to something other than UTC). Hmm, just looked more carefully at the docs. I see I'm going to have to add a prefs setting so the user can tell my app what timezone they are in. I find it odd that the OS can't provide this information. -- Cheers -- Tim -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

For the same reason, I don't want to start modifying or creating a php.ini file. In that case, you might consider setting it via the Apache config file that you're creating, which you can do with something like: php_value date.timezone 'America/Phoenix' OK. That'll have the same effect (and benefits) as setting it via php.ini. Hmm, just looked more carefully at the docs. I see I'm going to have to add a prefs setting so the user can tell my app what timezone they are in. I find it odd that the OS can't provide this information. Well, it typically can, or at least can make a guess at it. The problem is that it's not something you can rely on across different OSes, as some handle it differently, or less reliably, or not at all. Basically, the result is non-deterministic. It's for this reason that, as of 5.4, PHP won't even ask the OS but will always return UTC (and complain a bit) if something else hasn't been set. This way, you at least have a chance of consistent results. If you're only supporting OS X, you can have your script that generates the Apache config file retrieve the system time zone, and then use that value in the php_value setting. If the script is in PHP, you can do this: $timeZone = `/usr/sbin/systemsetup -gettimezone`; Which just calls the systemsetup command line utility (basically, a CLI front-end to the settings controlled via System Preferences). Here's what that call returns when run on the command line on my system: H012316WHPV:~ rewilliams$ systemsetup -gettimezone Time Zone: America/Phoenix That is a very helpful hint - thanks. Yes, it's OS X only at the moment as I don't have access to or a great interest in the other platforms. Not sure if this has greatly help the OP though :-) -- Cheers -- Tim -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

The php statements I posted were the first few statements in the script, so apparently the script didn't see the variables, so I'll have to review the httpd.conf and php.ini files to find whatever settings is preventing the acctnum, year, and month from being passed to the php script. You say: I opened the html file using IE 6.0 I don't like the sound of that. Do you mean you double-clicked the file and it opened in IE or do you mean you put Q:\... into the IE address bar or what?

Well, that's going to be part of it, but it's never going to work if you open it via Explorer. If you do that, apache won't be involved whether it's running or not. This will only work if you have IE (or other browser) open and put http://localhost/your-webpage.html into the browser's address bar. Further, both the webpage and PHP file need to be in your document-root.

I've not used a goto since I stopped writing in FORTRAN in 1978, and not missed it [1]. Neither do I ever have deeply nested if-then-else - these are a good source of bugs. I suppose the rest of your article might have been dealing with simplifying val_nested() but TBH I wasn't interested enough to find out. [1] Not quite true - a Pascal compiler I once had to use in 1983 lacked a return statement, so I had to fake it by putting a 999: label at the end of the function and goto-ing to that. -- Cheers -- Tim -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I was one of the proponents who argued on internals for its inclusion several years ago. I stand by its utility and refer the reader to the fact that many open source projects, especially ones that use some kind of parser, have goto hidden within their implementation. You can find it in the C code for the PHP, MySQL, and Apache to name a few easily recognizable projects. All of which is no doubt true but that doesn't mean I have to like it, although obviously I'll have to put up with it.

I guess what I meant was, that I'd never have written it that way in the first
place, so as an example it felt contrived. Amateurs or people with no training
(in particular physicists at CERN 40 years ago) should be kept well clear of
the goto. I'd probably write your function like this:
function val_nested ($name = null, $value = null, $is_mutable = false)
{
static $values = array();
static $mutables = array();
if ($name===null) return $values;
if ($value===null) return isset($values[$name]) ? $values[$name] : null;
if (isset($values[$name]))
{
if (!$val_is_mutable = in_array($name, $mutables))// Set existing
value
{
$msg = 'The value ' . $name . ' is immutable and has already
been set to ' . $values[$name] . '.';
throw new Exception ($msg);
}
return $values[$name] = $value;
}
if ($is_mutable) $mutables[] = $name; // Set new value
$values[$name] = $value;
return $value;
}
I always add blank lines for clarity. Remove those and the above is 30% shorter
than yours - as far as I could tell, none of the else clauses was required.
My approach is:
1) deal with the trivial and error cases first
2) deal with the real work next

Think of a function that can fail in several different places (eg data validation, ...). But it is reading a file which needs to be closed before the function returns. I have seen code where some $IsError variable is tested in many places to see if things should be done. That is just as bad as lots of GOTO -- often when having to write something like that I will have a GOTO (in Good code uses Exceptions and try catch for that kind of scenarios. Exceptions have a lot of overhead and should only be used in exceptional circumstances. I don't see how data validation failing is an exceptional circumstance. I find that using Exceptions and try/catch for something this trivial to be more confusing and harder to read (thus worse code) than a goto. It is also much easier to make a mistake, especially if you're expecting the catching to happen outside of the validation function. While it is true that try/catch adds another level just like an extra if-then-else, there are times when it's unavoidable. During initialisation of my app, I have to check which of the files in a directory may be SQLite databases that belong to the app. So I have to check: a) whether this file is an SQLite database b) whether it has the two tables I expect to find there Last time I checked the SQLite API in question, it looked as though try/catch was my only option. -- Cheers -- Tim -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
