I have some really strange behaviour going on here, and I think it could
be
a (minor) PHP's bug.
I am not really sure about what happens internally, but my best guess
would
be that after a memory exhaustion, when I try to execute a custom error
handler with the register_shutdown_function (which is executed even after
a
fatal error) and try to access the element that provoked the memory
exhaustion, no error should raise instead of *Uninitialized string
offset:
0.
I have prepared a little test case to reproduce the error and (I hope)
can
explain the error.
?php
date_default_timezone_set('America/Santiago');
ini_set('memory_limit','1M');
ini_set('display_errors',1);
error_reporting(-1);
function my_error_handler($errno = '0', $errstr = '[FATAL] General
Error',
$errfile = 'N/A', $errline = 'N/A', $errctx = '') {
This seems to be your error. You set $errctx to be a string. But later on
you use it as an array.
Remove the = '' part. And it will function as expected.
You're right... However I don't like leaving non-default value in functions
so I did something like if(empty($errctx)) $errctx = array() in the first
line of the custom error handler which threw out the error message and
everything works ok now.
I think from 5.2 and up you can use the array keyword to force an array
as parameter..
But -and correct me if I'm wrong- isn't isset (or empty) supposed to return
a FALSE whenever that variable doesn't exist?
With your help, I could reduce the test case into:
$asdf = 'hello world';
if (empty($asdf[4]['inventing'])) echo 'nice little world';
if (isset($asdf['inventing'][6])) echo 'little nice world';
// This works ok.
This works because the string $asdf is set with a value. So $asdf[4]
exists but ['inventing'] doesn't so it will return false
$asdf = '';
if (empty($asdf[4]['inventing'])) echo 'nice little world';
if (isset($asdf['inventing'][6])) echo 'little nice world';
// This returns E_NOTICE
This doesn't work because the string $asdf is empty. So calling $asdf[4]
will trigger a notice since there is no 4th character
Shouldn't these 2 examples work exactly the same way? (AKA as Nº 1). If
not... why not? Both are string types, onyl difference is that one has no
characters in it while the other does, but essentialy they are both the
same.

[PHP] Xpath arguments in variable
Hi
I have the following statement that locates the node membernumber with
the value A192. This works perfectly fine.
$v = $row-xpath('//membernumber[. = A192]');
But now I need to pass this value to XPath within a string variable say
$v = $row-xpath('//membernumber[. = $MemberId]');
But this doesnt work due to the quotes. What I intend PHP to do is to
substitute the value for $MemberId and then execute the XPath query. I
have grappled with it for a few days before posting this. Any ideas are
most welcome
Best regards
Sridhar

Use double quotes instead, which should allow PHP to expand the
variables.

The $MemberId should be substituted with A192 and then the xpath query

[PHP] Re: Xpath arguments in variable
If you needed the double-quotes in the Xpath expression when the constant is
used , then you probably need them in the variable version.
$v = $row-xpath('//membernumber[. = '.$MemberId.']');
That should put the double-quotes in for you...
