equal
I would expect PHP to be evaluating string 444-4 against integer 444
(or string either way)
however, just for giggles, using === works...
php if ($id === intval($id)) echo 'equal'; else echo 'not equal';
not equal
Using === will always fail because on the left you have a string and on
the right you have an integer which fails exact comparison based on
datatype mismatch.
When comparing a string to an integer using == PHP performs type
juggling and converts the string to an integer first.

Using == will compare the two values after type juggling is performed. === will
compare based on value and type (identical).
PHP Will type juggle the string to an integer.
Your if/else is just like saying:
php if (444 == 444) echo 'equal'; else echo 'not equal';
equal

Try unsetting the $row variable, you may be fetching extremely large rows but
that's a big if, because your script is allowed to allocate 128MB of memory
before puking. Are you dealing with very large data sets from the database? If
you are dealing with large data sets, then try redefining your query.

If you are dealing with large data sets, then try redefining your query.
I don't think that will help, as it gets reset each time it iterates the
loop when it's given a new value.
Have you tried narrowing down your query to only the fields that you
need in your script? Instead of SELECT * FROM test_table try something
like SELECT field1, field2, etc FROM test_table
Another thing to try is running this in over the command line if you
can. I've had a lot of success with memory intensive scripts like this.
Although it may not help in your specific case, it's worth noting at
least.

James:
Thanks for taking time to help.
The row size is small by my standards (see below). The query result
has just under 300,000 records, and it's puking about 90% of the way
through.
Changing the while loop to:
while ($row = mysql_fetch_assoc( $result )) {
$n++;
echo sprintf( %7d %12d\n, $n, memory_get_peak_usage() );
} // while
the tail end of the output becomes:
274695134203084
274696134203524
274697134203964
PHP Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to
allocate 240 bytes) in xx3.php on line 26
Changing the while loop further to:
while ($row = mysql_fetch_assoc( $result )) {
unset( $row );
$n++;
echo sprintf( %7d %12d\n, $n, memory_get_peak_usage() );
} // while
the tail end of the output becomes:
274695134202232
274696134202672
274697134203112

274699134203992
PHP Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to

So it does get a little farther through the dataset, but not much.

One of the key concepts of troubleshooting is that when you encounter a problem, you try to state the problem with as simple a test case as possible, so that testing will not be complicated by extraneous variables or code that may or may not have any impact on the problem. I don't want to just count the records, I want to get some work done for a client. That work involves processing every record in the result set. Counting is just a simple process to conduct for the purpose of debugging this loop algorithm. The problem is that this algorithm fails to process all the records in the result set.

I was glad to learn what comments were.
Eric: Please forgive me if I was curt in my message to you. I
don't mean to bite the hands that are trying to help. As Daniel
rightly observed, my concern is just that if a pretty much empty
while loop runs out of memory when trying to step through each
record, I'm really going to be hosed if I try to start doing some
productive work within the while loop.
Daniel's memory trend analysis is helpful. I'm testing from the
command line, so there's no Apache overhead, but the memory usage
starts as:
1 12145496
2 12145976
3 12146408
4 12146804
5 12147200
6 12147596
...
I normally prefer to work in PostgreSQL, but the client has already
gone down the MySQL road. Just for edification's sake, I exported
the table in PostgreSQL and re-worked my code:
if (!($db_conn = pg_connect( host=$db_host user=$db_user dbname=$db_name
password=$db_pwd )))
die( Can't connect to SQL server\n );
$qry = select * from test_table order by contract;
if ($result = pg_query( $db_conn, $qry )) {
$n = 0;
while ($row = pg_fetch_assoc( $result )) {
unset( $row );
$n++;
echo sprintf( %7d %12d\n, $n, memory_get_peak_usage() );
} // while
pg_free_result($result);
echo $n\n;
} else {
die( pg_last_error() . \n );
}
Using PostgreSQL (on a completely different machine), this runs
to completion, and memory consumption is nearly flat:
1 329412
2 329724
3 329796
4 329796
5 329796

295287 329860

If one were to describe the memory consumption as a 'leak', then
PostgreSQL is leaking at a much slower rate than MySQL. Postgres
leaks as much over the entire run (329860-329412=448) as MySQL
does on each row. Put another way, the MySQL version leaks
memory almost 300,000 times faster.
My PostgreSQL machine also has MySQL installed, so I ran the
MySQL version of the code on that machine for testing, a second
opinion if you like. It leaked memory almost as bad as my
client's PHP/MySQL installation, but a little more slowly, 396
bytes or so per row. The slower memory consumption enabled the
code to run to completion, barely:
1 12149492
2 12149972
3 12150404
4 12150800
...
295284129087704
295285129088100
295286129088496
295287129088892
295287
So is this just a difference in the programming quality of the
database extensions for MySQL vs. PostgreSQL that one gobbles up
memory profusely, while the other one has only a slight, slow
leak?
I will try experimenting with Daniel's idea of unbuffered
queries, but my understanding is that while an unbuffered result
resource is in use, no other SQL transactions can be conducted.
Maybe I can get around that by using one MySQL connection for the
unbuffered query, and another separate MySQL connection for the
incidental SQL queries that I need to perform as I process each
record from the large dataset.

The script below is designed to be able to WHILE it's way through
a MySQL query result set, and process each row.
However, it runs out of memory a little after a quarter million
rows. The schema fields total to about 200 bytes per row, so
the row size doesn't seem very large.
Why is this running out of memory?

mysql_fetch_array() grabs all of the data and places it in a
simple numerically-keyed array.
By contrast, mysql_fetch_assoc() grabs it and populates an
associative array. This means that the column names (or aliases, et
cetera) become the keys for the array. With mysql_fetch_assoc(), you
can still call an array key by number, but it's not vice-versa with
mysql_fetch_array().
The difference in overhead, if you meant that (in which case, my
apologies for reading it as a question of functional difference), is
variable: it's based mainly on the difference between the bytes
representing the integers used as keys in mysql_fetch_array() versus
the size in bytes of the strings used as keys in mysql_fetch_assoc().

I'm not seeing any numeric keys in my mysql_fetch_assoc() arrays.
However, mysql_fetch_row (by default) does both: the array will be
indexed numerically from 0 to N-1 corresponding to the table's N
columns, and the array will also have string key indices which
correspond to the query's column names. So by default,
mysql_fetch_row uses twice the amount of data, because each field
appears in the array twice.
var_dump( $row ) will show in graphic detail.

Its the same thing but you are fetching data in chunks.
Now this portion order by contract on quarter million rows is not a
good practice. It will slow down your query time and make the script
severely slow.
I had about 100 millions of rows in my table in the url and I was
sorting on last-visit column. Later I removed the order by and it was
much faster.
Try it and let us know.
Thanks

Re: [PHP] Why is this array_walk_recursive action not working?
Hi,
Well, first array_walk_recursive returns a boolean so what you are doing in
you script is append a boolean (true or false) that will be converted to
string. So if array_walk_recursive will return true you will have the string
1 in $karamohOutput['test'], and if array_walk_recursive will return false
you will have the empty string in $karamohOutput['test'].
I think what you're after is this:
$karamohOutput['test'] = ;
foreach ( new RecursiveIteratorIterator( new RecursiveArrayIterator(
$karamohArray ) ) as $key = $item ) {
$karamohOutput['test'] .= $key holds $item\n;
}

if you read the following page description of the function, you will see that
the function returns a bool value. Not the return statement of your custom
function call.

If you read the Note under the funcname section, you will see that when you call
the function, it will pass the value as a reference, so, change around your
function like this.

More likely is that folks often expect PEAR to be the end-all, be-all, and that was never the intent. PEAR is supposed to jump-start a project and extend some built-in functionality, not provide a framework or do all of the work for folks who consider themselves programmers because they can iterate an array in just twenty-seven lines of procedural code. As for folks who say that PEAR and PECL don't work --- the most common reason for this is user error or system configuration issues.

Re: [PHP] Why does CURLOPT_FOLLOWLOCATION require open_basedir to be turned off?
Hi, I was wondering why CURLOPT_FOLLOWLOCATION requires open_basedir and safe_mode to be turned off. The following was found in the changelog(http://www.php.net/ChangeLog-5.php): Disabled CURLOPT_FOLLOWLOCATION in curl when open_basedir or safe_mode are enabled. (Stefan E., Ilia) I'm guessing that it would allow CURL to follow a link if a server returned a 301 or 302 redirect. For example, a PHP script consumes a web service or fetches a webpage from another server, then all of a sudden that remote server sends a 301/302 redirect to a malicious page, CURL would then follow the redirect instead of returning an error. If a server admin is paranoid enough to use safe_mode, they probably wouldn't want that to happen (note saying that being paranoid is a bad thing, but I've been managing PHP systems for years without safe_mode or open_basedir and never had an issue, but I can see why hosting providers may enable it.) I can't see any conceivable benefit to this restriction when using open_basedir, as I thought that related to the local file system - unless CURL can use file:// URLs to access the local system?

Re: [PHP] Why does CURLOPT_FOLLOWLOCATION require open_basedir to be turned off?
I can't see any conceivable benefit to this restriction when using open_basedir, as I thought that related to the local file system - unless CURL can use file:// URLs to access the local system? That's the problem. I always use open_basedir (not all the sites on my servers are safe enough). And that so called security restriction just makes me fury (unless I don't see significant reasons for it). So, in order not to irritate my nervous system every time somebody asks me to unset open_basedir for CURL I decided to find the roots of that PHP developers' action. And I don't think it's related to the local file system: there is another option that restricts protocols while redirecting, CURLOPT_REDIR_PROTOCOLS, which allows by default all the protocols supported by CURL, but file and scp. So this kind of restriction (do not follow file:// while redirecting) would make sense, but not disabling FOLLOWLOCATION at all. Either they had a better reason or they messed up a bit :) Still trying to find a better explanation. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Why getcwd() returs different results?
Here's an example from the PHP website:
This demonstrates the behaviour:

echocwd();
register_shutdown_function('echocwd');
?
Outputs:
cwd: /path/to/my/site/docroot/test

Can't this be fixed so that the path returned is consistent across servers?
It would appear that PHP should set the CWD path before calling the shut down

What shutdown functions are you meaning? Do you have an example which shows the

Sorry this is isn't good 'ninja' material.. but I gotta start where I am.
this:
echo 'is set (EditExistingClient) ='. isset($EditExistingClient).br /\n;
is returning:
is set (EditExistingClient) =1br /
but this, later down the page:
elseif ((isset($EditExistingClient)) || ($CreateClient)) //we just created a
client, OR edited a client
{
echo 'input name=EditExistingClient type=submit value=Edit This
Client'.\n;
}
is not firing unless $CreateClient is set.
This, too, is not firing when I think it should:
elseif (($EditExistingClient) || ($CreateClient)) //we just created a
client, OR edited a client
{
echo 'input name=EditExistingClient type=submit value=Edit This
Client'.\n;
}
what ridiculously simple thing am I missing?
The only possibility I can see is that $EditExistingClient is getting
modified between the echo and the first elseif statement.

Re: [PHP] why is this shell_exec() failing to execute my shell to create a symlink?
Make sure that:
- The user executing the script (apache I presume) has execute
permissions on ls and ln binaries.
- The user executing the script has write persmissions on the
directory you are trying to write, and read permissions where you do
ls.
- This will probably help: put the full binary path for ls and ln, it
depends on your OS, but probably they are: /bin/ls and /bin/ln
If that doesn't help, can you show us the output?

I'm trying to use

Why does it give me sub-objects and not just empty strings for tags that
have no values as I'd expect??!
first off, why does it matter.
second, i dont think its a bug, thats just how it works,
php $a = simplexml_load_string('blah/');
php var_dump($a);
object(SimpleXMLElement)#1 (0) {
}
I tried all those options above and none of them make a difference.
SimpleXMLElement Object
(
[crstatus] = i_field_submitted
[problem_number] = 151827
[problem_synopsis_field] = title
[problem_description_field] = description2
[fi_priority] = High
-- [assignee] = SimpleXMLElement Object
(
)
-- [fi_notes_oem] = SimpleXMLElement Object
(
)
[fi_sw_part_name] = sw_part_name
[fi_general_reference] = general_reference
[fi_sw_part_number] = sw_part_num
[fi_customer_ecd_date] = 1244703600
[fi_sw_part_version] = sw_part_version
[fi_required_date] = 1243839600
-- [ac_type] = SimpleXMLElement Object
(
)
)
third the documentation says var_dump() / print_r() are not supported, so i
wouldnt put much stock in the dump of the object above.
from the manual:
http://us2.php.net/manual/en/function.simplexml-element-attributes.php
*Note*: SimpleXML has made a rule of adding iterative properties to most
methods. They cannot be viewed using
var_dump()http://us2.php.net/manual/en/function.var-dump.phpor
anything else which can examine objects.

Shouldn't be max execution time issue if he's running the CLI. Maybe
account limits? Maybe the above snippet isn't what's really happening...
I mean what purpose would the above script serve for 3 hours? Looks like
it's been dumbed down for us dummies on the list.

RE: [PHP] Why [?php while (true) { sleep(5); } ?] dies on CLI?
One of two things is happening:
- PHP is crashing, maybe a memory leak, etc.
Or
- That while(true) loop is exiting, and the script is completing.
Would be interesting to know which, try adding this after the loop:
$fp = fopen('/tmp/test','w');
fputs($fp, 'My script left the loop and exited cleanly. True ==
false.');
fclose($fp);
Back on my first point, have you kept an eye on the memory usage over
the 3 hours? If your version of PHP has a memory leak with while() or
sleep() (would be odd), a bazillion iterrations could break the PHP
defined memory limit (8M by default) and cause it to exit abruptly.
Are you capturing the output anywhere? For example, in Linux is it
being run from cron or another script? Try redirecting STDOUT and
STDERR somewhere useful, i.e.:
php my_php_script /tmp/scriptoutput 21
(21 means output stream 2 [stderr] to the same place as stream 1)
Hope any of these crazy ideas are helpful...

Re: [PHP] Why does PHP have such a pain in the a$$ configuration file?
phpinfo() will help you to find the differences in the configuration... i do this every time i move to a new host(before uploading any other files to the server, of course i delete it afterward) and change my pages accordingly. most of the configuration settings in php.ini can be overridden by ini_set().

Perhaps you're not at all clear on the purpose of a configuration file. I am seriously considering moving to a different language because of this. I guess you could look for a language that has a parser with 0 configuration options. Sounds like a bundle of fun.

Could you tell us what configuration setting they have changed? I wasn't

In addition to what Rob said, the only other option would be
implicit_flush, which is ridiculous if it is set to on.
Maybe the file that you're evaling has some ob stuff or flush() in it?

and you can use DOMDocument to completely
construct the page before sending it to the browser - allowing you to
translate xhtml to html for browsers that don't properly support
xhtml+xml.
I suspect you meant translate xml to html? I publish everything in
xhtml, no browser has had a problem with that yet.
IE 6 does not accept the xml+html mime type. I don't believe IE7 does
either, I think IE 8 beta does but I'm not sure.
If you are sending xhtml with an html mime type you are breaking a
standard, even if it seems to work. xhtml is suppose to be sent with the
xml+xhtml mime type.
by translating from xhtml to html 4.01 you can send the text/html mime
type to browsers that don't report they accept applicatoiion/xml+xhtml
and send them standards compliant html.
By using DOMDocument it is really easy to do.
Standards compliance is important, and it isn't hard to achieve.
The following is the filter I use for browsers that don't accept xml+html:
function HTMLify($buffer) {
/* based on
http://www.kilroyjames.co.uk/2008/09/xhtml-to-html-wordpress-plugin */
$xhtml[] = '/script([^]*)\//';
$html[] = 'script\\1/script';
$xhtml[] = '/div([^]*)\//';
$html[] = 'div\\1/div';
$xhtml[] = '/a([^]*)\//';
$html[] = 'a\\1/a';
$xhtml[] = '/\//';
$html[] = '';
return preg_replace($xhtml, $html, $buffer);
}
That's only part of the work, but it is the most important part.
Note that that doesn't translate all valid xhtml - it doesn't for
example take into account legal whitespace that DOMDocument doesn't
produce. If you want more robust translator, use an xslt filter, but
this function is simple and doesn't require the various xslt parameters
and libraries at php compile time.
When I create a new DOMDocument class instance -
$myxhtml = new DOMDocument(1.0,UTF-8);
$myxhtml-preserveWhiteSpace = false;
$myxhtml-formatOutput = true;
$xmlHtml = $myxhtml-createElement(html);
if ($usexml == 1) {
$xmlHtml-setAttribute(xmlns,http://www.w3.org/1999/xhtml;);
$xmlHtml-setAttribute(xml:lang,en);
}
when the document is created - instead of printing the output I save it
as a variable and then add the proper DTD:
function sendpage($page,$usexml) {
$xhtmldtd=\n!DOCTYPE html PUBLIC \-//W3C//DTD XHTML 1.1//EN\
\http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd\;\n;
$htmldtd=!DOCTYPE html PUBLIC \-//W3C//DTD HTML 4.01//EN\
\http://www.w3.org/TR/html4/strict.dtd\;;
if ($usexml == 0) {
$bar=preg_replace('/\?xml version=\1.0\
encoding=\UTF-8\\?/',$htmldtd,$page,1);
$bar = HTMLify($bar);
} else {
$bar=preg_replace('/\n/',$xhtmldtd,$page,1);
}
sendxhtmlheader($usexml);
print($bar);
}
I add the DTD there with preg_replace because I haven't yet found a
DOMDocument way to add it, which is how it should be done - someone told
me the DTD is currently read only in DOMDocument and that in the future,
I'll be able to add it when a new DOMDocument class is created, so for
now, the preg_replace hack works, and I might keep it that for some time.
To determine whether or not to send xhtml - when the page is requested
(before any of that other code is executed) the following code is run:
if (! isset($usexml)) {
$usexml=1;
}
if ($usexml == 1) {
if (isset( $_SERVER['HTTP_ACCEPT'] )) {
if(! strpos( $_SERVER['HTTP_ACCEPT'], application/xhtml+xml ) ) {
$usexml=0;
}
} else {
$usexml=0;
}
}
The sendxhtmlheader function:
function sendxhtmlheader($usexml) {
if ($usexml == 1) {
header(Content-Type: application/xhtml+xml; charset=utf-8);
} else {
header(Content-type: text/html; charset=utf-8);
}
}
Anyway - all that is in a file I call xhtml.inc that I include in all
my pages, then to build the document, I use the $myxhtml object that
include creates. To send the document to the browser -
$foo=$myxhtml-saveXML();
sendpage($foo,$usexml);

What happens is IE6 (and I believe IE7) asks the user what application they want to open the file with if it receives an xml+xhtml header. IE does parse xhtml but only if sent with an incorrect html header. IE8 is suppose to fix that, but it will probably take years before IE6/7 is for all practical purposes out of circulation. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
