How can i check if a string is URL encoded or not using PHP

I have an array of $fl
By using values of this array, i want to create a new string.
I need string size will be maximum 200 characters.
When i try below code snipped, $f value is added to string two times.
How can i add $f to array only one time, with checking size of string.
Thank you

Code: [Select]
$fl=getsomelist(); // gives an array
$userList='';
foreach ($fl as $f) {
    if ( strlen($userList .= $f) <= (200) ) {
        $userList .= $f;
    } else {
        break;
    }
}

I want to allow Alphabetical strings, Numeric strings, and Alphanumeric strings. For example "Bob", "1234", "bob1234" are all valid.

I want to check if the string has invalid characters, return true if it does (or false, which ever method works).

How can I do it?

Hey.

I been using a function to check if a string contains only letters which is:

ctype_alpha

But i would like to change it to allow numbers 0 to 9 and the letters is there a function to do that in PHP i can't find it.

I was wondering if anyone knows a good way to check for an even number of each character in a string.  For example if the string is "abbacc" then it will return true as there are two of each character.  However if the string is "ababc" it will return false as there is only 1 c.  Thanks for any help

Hi all, i've got a string ($currentcatid) which contains one number which changes dependant on which page the visitor is on.. ie  it may be perhaps "23" or "17" .

I need to do a check against this string to see if it contains any of the following values .. 31,32, 1, 24 . I cant remember how i did it before but i think it was with pipes..

something along the lines of
if ($currentcatid =="31"||"32"||"1"||"24") { action }

can anyone help?

Thanks

I want to check if a string has any of words listed in array;
Code: [Select]
$array=array('word1', 'word2', 'word3');
$string="This is a sentence containing word2";
Now I want to make an 'if else' to check if the string contains any of the words listed in the array. Thanks 

Hello guys, I have a form where you can select a score between 0 and 10(only integers). I want to check if the value that I recive, is integer.   Im using this code(exemple):

$integer =  intval($_POST["p1"]);
    if(is_int($integer)){
        echo 'INT';
    } else {
        echo 'NO INT';
    }

My problem is that if it recive letters, the conversion converts it to 0, and it says that it is integer. So with this method I should discard the 0.   You guys know a method to avoid that?   Thank you guys

I have a web server which contains a public site and a private site. I want to be able to test for public or private using the page title and return the appropriate header which contains a different banner, css etc.

Firstly - the syntax below seems to be incorrect because it doesnt work correctly.
More importantly how do I add all the values to an array and than iterate through it to check for a matching page title?

Code: [Select]
public function publicSite() {
if ($this->getTitle()== 'Home' || 'About Us'||'Registration' || 'Sitemap' || 'Contact Us' || 'Useful Links' || 'Feedback') {
return true;
}
return false;
}
Then later on I would have:
Code: [Select]
if ($this->publicSite()) {
require($ROOT.'interface/pages/publicheader.php');
}
else {
require($ROOT.'interface/pages/privateheader.php');
}

Thanks heaps!
