What is utf8

Unicode is a character set supported across many commonly used software applications and operating systems. For example, many popular web browser, e-mail, and word processing applications support Unicode. Operating systems that support Unicode include Solaris Operating Environment, Linux, Microsoft Windows 2000, and Apple’s Mac OS X. Applications that support Unicode are often capable of displaying multiple languages and scripts within the same document. In a multilingual office or business setting, Unicode’s importance as a universal character set cannot be overlooked.

xml 2 array and array to xml

I’ve tried this function with google feed but doesn’t seem to work. I haven’t look into details of it yet anyways you can try it and give it a shot. You can also use this for array to xml. Just check the link of the original post for more info.

PHP: XML to Array and backwards

Here the XML with PHP solution: XML->Array and Array->XML.
Work with it as with usual array.

Format XML->Array
_c - children
_v - value
_a - attributes

This is 1.1

Example #1 (1.xml):

<ddd>
<onemore dd="55">
<tt>333</tt>
<tt ss="s1">555</tt>
<tt>777</tt>
</onemore>
<two>sdf rr</two>
</ddd>

The code:

$xml=xml2ary(file_get_contents(‘1.xml’));
print_r($xml);

Here is the Array result:

Array
(
[ddd] => Array (
[_c] => Array (
[onemore] => Array (
[_a] => Array (
[dd] => 55
)
[_c] => Array (
[tt] => Array (
[0] => Array (
[_v] => 333
)
[1] => Array (
[_a] => Array (
[ss] => s1
)
[_v] => 555
)
[2] => Array (
[_v] => 777
)
)
)
)
[two] => Array (
[_v] => sdf rr
)
)
)
)

Call-time pass-by-reference has been deprecated

Got this error and after some digging I found a solution. It was listed below. But looking back into my code I noticed that I called the function twice and used it incorrectly that caused the error!. Anyways, aside from that in case you encountered this error you can have the solution below

Warning: Call-time pass-by-reference has been deprecated - argument passed by value; If you would like to pass it by reference, modify the declaration of [runtime function name](). If you would like to enable call-time pass-by-reference, you can set allow_call_time_pass_reference to true in your INI file. However, future versions may not support this any longer

Solution:

For the Warning: Call-time pass-by-reference, in c:\EasyPhp\apache
\php.ini set :
allow_call_time_pass_reference = true

[function.main]: failed to open stream: Permission denied

Warning: … [function.main]: failed to open stream: Permission denied

Warning: main() [function.include]: Failed opening … for inclusion (include_path=’.:/usr/lib/php:/usr/local/lib/php’) in …

I wanna bear in mind that this error has something to do with file permission coz at first glance I just checked the path of the included file but looking closely it has something to do with the file permission. Changing it to 755 solved the issue.

And one more thing, I had this error_reporting(E_ALL && ~NOTICES); on my script and can’t see why my included file is not functioning. I’ve been looking what could be the error. Commented this error_reporting(E_ALL && ~NOTICES); kuala!!! I found the Warning msg! so be sure to comment this line when debugging your code or else you’ll get crazy looking for the error

Warning: mysql_real_escape_string() [function.mysql-real-escape-string]:

Warning: mysql_real_escape_string() [function.mysql-real-escape-string]: Access denied for user ‘apache’@'localhost’ (using password: NO)…

I’m having that error for using mysql_real_escape_string in one of my functions. Checked php manual and it says u need to have mysql connection to use that. well.. my bad…coz I’m using it in a variable before putting in a query. This is an example on how to use it anyway…


// Connect
$link = mysql_connect('mysql_host', 'mysql_user', 'mysql_password')
OR die(mysql_error());

// Query
$query = sprintf(”SELECT * FROM users WHERE user=’%s’ AND password=’%s’”,
mysql_real_escape_string($user),
mysql_real_escape_string($password));
?>

[function.move-uploaded-file]: failed to open stream: Permission denied

[function.move-uploaded-file]: failed to open stream: Permission denied

Encountered this error. I’ve checked the path, permission it’s all correct. Then I tried changing the permission of the folder on where to move the files to 777… problem solved. Thanks God!

Virtual Class — cannot instantiate

I’m getting this error Virtual Class — cannot instantiate within nested class/functions. I checked the class reported by the error and instead of using extended class when using other class inside that specific class, I used class::function, it solved problem.

[function.getimagesize]:could not make seekable

I’m getting this error using the function getimagesize: [function.getimagesize]:could not make seekable

I’ve checked the path it’s right, checked if the image existed. It was. I took a closer look on the details of getimagesize on php manual for the accepted file types and it says jpg file type and mine was jpeg. MOdified it using photoshop to jpg file type and it solved my prob
