Hi guys and lovers of PHP.
I will be posting some other the everyday challenge I encountered while working with Php.
I invite you to join me.

This happened today, it was my first time working with zip file.
The issue came up when i opened the file like this:

$zFile = $zip->open($filePath,  \ZipArchive::OVERWRITE);
$zip->extractTo($bookDir);

After opening the file i was trying to extract to another directory, this returns true but no extracted data was found.
The is a really troublesome bug, but thank God for the internet.
After sometime i debugged and removed the \ZipArchive::OVERWRITE and it worked.

$zFile = $zip->open($filePath);
$zip->extractTo($bookDir);

You can call a field from you database constantly using jquery Ajax with the set time interval function of javascript.
The ajax should be call you php script the fetch info from db like every 10s or how ever you want it.

Search and replace string in php.
Search and replacing string is not difficult using the function str_replace();
I have to search a string (actually an html content which i extracted from a file using file_get_content()), string to was src=" and replace with src="http://path/to/the/image/folder/ and i acheived this by simply

str_replace('src="','src="http://path/to/the/image/folder/',$str);

Yes you can, am sure every PHP develop is glad to assist you.

I was working with a script developed by something else and i got hooked because i could not post content due to some logical issue with the programming of the script.
The script was design to upload file whether empty or not and this was causing problem for me because i am not attaching a file to the post.
Here is the code to here detect if the file upload is not empty:

if(!$_FILES["file"]['error'] == 4){ //process upload }

That solves the issue, i could now post without upload a file.
