[PHP] Possible bug with imagettftext and imageft text when imagealphablending is false
I have been attempting to write a dynamic text replacement script that would generate transparent PNGs using gd, and it works fine except when one of the characters in a font has parts of it that overhang into the previous characters. You can see what I mean in this test script: ?php $img = imagecreatetruecolor(200, 200); imagealphablending($img, false); $trans = imagecolortransparent($img); imagefilledrectangle($img, 0, 0, 400, 400, $trans); $green = imagecolorallocate($img, 6, 68, 0); imagettftext($img, 30, 0, 10, 50, $green, carolingia.ttf, Linux); header(Content-type: image/png); imagesavealpha($img, true); imagepng($img); imagedestroy($img); ? The result can be seen at http://ethilien.net/tests/text.php When you compare the text with what it should look like when I comment out the imagealphablending($img, false); line here http://ethilien.net/tests/text2.php you can see that the end of the 'u' is cut off. I think that this is because the lower-left slash of the 'x' overlaps it and causes it to be overwritten. This might be a bug in GD and not PHP, but I wanted to see if anyone has encountered this problem before or if I'm just not doing something right.

[PHP] Re: array_slice and for loop problem
Are you trying to put each return from array_slice into $output as an
array? You need to replace $output = array_slice... with $output[] =
array_slice...
Also, you cannot just echo an array (even of characters). It must be a
string, or else echo will only produce the output 'Array'.
Hope this helps,
-Connor McKay

Hello,
I'm using a for loop to iterate through an array and slice parts of
the array and add into another array.
When array_slice is called the variable $i is not being substituted
with the current value of
$i and the $output array is empty after running the script. Can
someone look at the code below and give me a clue as to why this
substitution is not happening? If I uncomment the echo $i; statement
the value of $i is printed just fine.
Thanks,
Rod
Here's my code:
$number = count ($int_range[start]);
//echo $number;
for ($i = 0; $i = $number; $i++) {
//echo $i;
$output = array_slice ($textArray, $int_range[start][$i],
$int_range[end][$i]);
}
foreach ($output as $value) {
echo $value;
}

[PHP] Re: How can I connect a remote server from phpmyadmin?
You need to edit the config.inc.php file in the phpmyadmin directory and set the appropriate server address/username/password information for your remote server. You might have to set a remote server up in cpanel for this to work however. MI SOOK LEE wrote: Hello, I have PhpMyAdmin 2.6.3 , MySQL 4.1.13 running in my Windows 2000.

[PHP] Re: Hidden Form Help
To answer your questions: 1) No, there is no way to make data show up in both fields because the script you are currently using is probably echoing the data directly into a value attribute of the elements themselves. Also, by making two different elements in the same form have the same name, and two different page elements have the same id, you are introducing a level of instability into the DOM that could result in no data being submitted at all if some browsers do not handle multiple occurrences of the same id in a page the same way (such as submitting the value from the first occurrence of the name rather than the last, resulting in the input in the hidden form being used). 2) Javascript would be your only hope of doing this, but as I said regarding the DOM, their is no way to independently access two page elements with the same id, so even Javascript cannot do this. I would recommend that, even though the application does not allow templating, you can still change its source code for displaying the form to allow you to template it that way. Hope this helps, -Connor Mckay Alnisa Allgood wrote: Hi- I'm in a situation where I'm required to deal with a hidden form. The background details are exhausting, but the gist is: one form is auto-generated and lacks proper formatting. It was part of an open source package that DID NOT allow templating. So to keep using the application engine, but provide formatting, I created a CSS class to hide the unformatted form while displaying the formatted form. When submitting data to the database this doesn't seem to cause any issues. It accepts data based on the fieldvalues and ids. But when retrieving data to repopulate the form, what happens is that the hidden form gets the values and the displayed form does not. http://nahic.ucsf.edu/phpESP/survey.php login= Wisconsin Basically, if you complete the required field (state), fill out some random data, hit save, then select resume from the info page provided. You'll get back an empty form. But if you look at the code you'll see that the hidden form has the values. So I have a few questions: 1) Is there anyway to echo data from one field to the next, especially if the field (name or id) are exactly the same?? (i.e. field=state value=Wisconsin; if the field state is then repeated somewhere else on the page, can the value, Wisconsin, also be automatically repeated. 2) If yes, to the above can PHP do this and how? or is this something requiring Javascript or some other coding. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] Re: mysql problem- I know it isn't strictly php
That last line always causes me problems, I think it is probably a difference in versions of mysql. Just change the last line to: ); without any of the text in their.

[PHP] Include path quirks
I've been attempting to write an application with a bit more ordered directory structure than I normally use, and I ran into the rather annoying problem with include() where relative paths are only based off of the current working directory, and not that of the included script. This makes it impossible to include script correctly, because the path from the working directory is different than that of the included file. The problem is I'm trying to include /include/global.php from /elements/nav.php but topnav is included by /index.php Which results in a failed top open stream error.
