From: [EMAIL PROTECTED]
Operating system: Linux Slackware
PHP version: 4.3.0
PHP Bug Type: Unknown/Other Function
Bug description: set_error_handler not properly executed?
Today we upgraded from php 4.2.3 (apache 1.3.26) to php 4.3.0.
We use freetype functionality in a set of functions and to keep this very
flexible the following code (except for the debugging prints) is used to
determine what freetype version was installed in order to use the right
functions (imagefttext or imagettftext).
This function (the set_error_handler) stopped working properly after
upgrading to 4.3.0
print freetype_version();
function freetype_version() {
// change error handler
set_error_handler("freetype_version_handler");
// remove freetype version from session
unset($_SESSION['freetype_version']);
// determine check array
$checkers = array(
"imagefttext" => 2, // freetype version
specific function -> freetype version
"imagettftext" => 1
);
// run checkers
while (list($key,$val)=each($checkers)) {
printf("%s:%s<br>\n",$key,$val);
eval(sprintf("%s();",$key));
}
// restore old error handler
restore_error_handler();
// return version (null = no freetype support)
return $_SESSION['freetype_version'];
}
function
freetype_version_handler($errno,$errstr,$errfile,$errline,$variables) {
print "errorrr!<br>\n";
if (eregi(sprintf("wrong parameter count for
%s",$variables['key']),$errstr)) {
$_SESSION['freetype_version'] = $variables['val'];
}
}
The code outputs the following error:
Fatal error: Call to undefined function: imagefttext() in
/sda6/domains/betterbeyourself.com_staging/includes/fnc_lang.inc(651) :
eval()'d code on line 1
We allready use a custom error handler so the above handler is nested...
this however worked very well in 4.2.3 I also noticed the same problems in
some 4.3.0 developmental cvs snapshots (don't know which snapshots they
were though) and thought it was a bug to be solved before the stable
release but appearantly it's still there....
Grtz,
Jeroen
