PHP - Removing Characters

Hi all,

I have an array of data. I am looping through this data to generate a CSV file. However, if there are commas in any of the elements then this will throw out the structure of the CSV file.

My question is, how do I loop through the array before I use it to strip out any commas and replace with a space?

Thanks for your help.

Hi all,

In my string I have hidden characters that has a shape of square. When I print the string, it shows questions mark. When I opened it with notepad, it show a square shaped character. I want to remove this character in my strings. I have searched the web. Somebody says its carriage return but i think it is not. Could you please help me with this issue. Thanks alot.

I have a string of mixed Japanese or Chinese and Western characters and I would really like to leave the western characters and remove the others. Is there any way to detect which UTF-8 characters are Japanese/Chinese and to remove them?

I have tried to use this which I found on another thread but my version of PHP (5.3) will not allow the /u in the following
Code: [Select]
echo "<BR>".preg_replace('/[^\u4E00-\u9FFF]+/', '', $string);
I have tried using various combinations of /p (these, plus others)
Code: [Select]
echo "<BR>".preg_replace('/\p{Bopomofo}+/u', '', $string);
echo "<BR>".preg_replace('/\p{Hiragana}+/u', '', $string);
and the /x{} option tells me the numbers are to large
Code: [Select]
echo "<BR>".preg_replace('/[^\x{4E00}-\x{9FFF}]+/', '', $string);
My string for this example is this but any combination of western and Japanese/Chinese characters are possible in the title.

Hey guys, im using UNIX time and trying to figure out how to remove the leading 0 when it shows the hour. "07:06 am" to make it read "7:06 am"

manual says i need to use %i with strftime. So I guess Im suppose to be removing the zero before the date format? which is why strftime isnt working after the date function. Or is there a way to do this in the date function.

                   $time = 1327493219;

date_default_timezone_set('UTC');

            $user_offset = date('h:i a  M/d', $time);

echo "<td>". strftime("%l",$user_offset) ."</td>"; 

What I want to do is simple:
The string "this_is_an_example.php"

should return "this_is_an_"

while:
"this_is_an_example_filename.php
should return "this_is_an_example_"

Is there a simple function which can cut off the part after the last _ ?
I have been looking and trying several functions, but can't seem to find the right one for this.

(the last _ being cut off of course wouldn't be a problem I couldn't live with :-) )

Any help will be greatly appreciated!

Hi

I want this URL:

php.net/manual/en/function.explode.php

to become

php.net

using php ..

I tried with the explode fuction but couldnt get it to work ...
list ($finalurl, $blabla) = explode('/', $url);

Anyone have any tips?

Thanks in advance

Hey guys.

How do you remove a specific element from an array?

Lets say I have a string like this:


$list = "guy,girl,boy,man,woman,lady";


Then I use explode to break it up into an array by commas:


$listArray = explode(",",$list);


Now $listArray contains everything. Now if I wanted to delete something specific from that array, how would I do that?
So for example, I want to delete "man" out of the array. How do I do that without know its key?
