PHP - Warning: Array_shift() [function.array-shift]: The Argument Should Be An Array I

PHP Warning:  file_exists() expects parameter 1 to be string, array given in /home/mysite/public_html/display.mysite.com/wp-content/themes/mytheme/form.php on line 9

PHP Warning:  file_exists() expects parameter 1 to be string, array given in /home/mysite/public_html/display.mysite.com/wp-content/themes/mytheme/form.php on line 13

I have a form that is having some issues and in the error log I see a bunch of these warnings. What is wrong with this??   I numbered the offending lines below (lines 9 & 13)   Thanks for any help on this.

function CheckExistance($VUrl)

{

/*9*/    if ( file_exists($VUrl) )

        echo $VUrl;

/*13*/    elseif ( file_exists(str_replace('www.display.mysite.com','www.display.com', $VUrl)) )

        echo str_replace('www.display.mysite.com','www.mysite.com', $VUrl);

    else

        echo str_replace('www.mysite.com','www.display.mysite.com', $VUrl);

}

hey guys!

Im trying to get hashtags out of a string.
The function works so far- but i cant transfer the insides of the preg_match_all array into the string.

A hint would be fine already.

Thanks in advance- and here is some code


Code: [Select]
<?php
//example string
$strcontent = "ima string... #wat #taggy #taggytag im in your stringz, stealing your charz!";
  
//find hashtags
preg_match_all("/(#\w+)/", $strcontent, $matches);
echo $matches;            //the output is just "array" -> why?
foreach ($matches as $match)
{
//  $tempmatch=$match[1]; #####like this?
        //hiding the hashtags via span
$strtemp="<br>ima span<br>" . $match . "<br>ima /span<br>" . $strcontent;
$strcontent = $strtemp;
echo $strcontent;
}
#echo $strcontent;
  
  # <span style="display:none;"></span>

and i'm having this error:
Sessions Values

Warning: Variable passed to each() is not an array or object in C:\xampp\htdocs\projet\sessions.php on line 33
 

please i need your helpppp

I have been scripting (some may say programming) in PHP for last 5 years but never faced this issue. Interesting!

Say for example, I created a custom function with one argument:

function myFunc($arg1) {
echo $arg1;
}

Now, if I call this function without supplying any argument it doesn't give any error/warning. Any other high level language like C++ or Java would produce error in this case. So, I had to modify my code as follows:


function myFunc($arg1) {
if (!isset($arg1)) {
echo "Missing argument 1";
}
echo $s;
}

But this is annoying. Now I have to add these EXTRA lines of code in every function and class methods I have created. Is there any shortcut/easy method that the script will always produce an error if its missing any required argument? I have tried with adding error_reporting(E_ALL); at the very beginning of my code. But it still didn't work out. By the way, I am using PHP 5.3.1 on Apache/2.2.14 (Unix).

Any suggestion will be appreciated.

Hey there,

This has me stumped here. I'm supplying an array as a valid argument to the class like so:

$mysql_configuration = array(

'MySQL_Host' 

=> "localhost",

'MySQL_Username' 

=> "fdsfdsfsdfsd",

'MySQL_Password' 

=> "sdf-sdf543",

'MySQL_Database'

=> "sfsdfsdfsdf");

$radio_core = array('Main' => new Radio_Core($mysql_configuration), 'Requests' => new Radio_Requests, 'Accounts' => new Radio_Accounts, 'Content' => new Radio_Content);


And here is my small class:


class Radio_Core
{

public $mysql_handle;

function __construct($mysql_array)

{

$this->mysql_handle = mysql_connect($mysql_array['MySQL_Host'], $mysql_array['MySQL_Username'], $mysql_array['MySQL_Password']);

if(!$this->mysql_handle)

{

die("The station failed to connect to the MySQL database.");

}

else

{

mysql_select_db($mysql_array['MySQL_Database'], $this->mysql_handle);

}

return 1;

}
}


And when it is called I am prompted with the error that the argument is missing for it?

any help is greatly appreciated.

Hi , can somebody help me with this warning? Warning: Invalid argument supplied for foreach() in /home/wwwdesig/public_html/mailer.php on line 12 It´s just a simple php mailer Here is the php code:       <?php if(isset($_POST['submit'])) {

I am a total newbie at PHP and I have a wordpress plugin that works well but sometimes does not return any results to the query which I believe is causing this error:

Warning: Invalid argument supplied for foreach() social-media-integrated-related-content-smirc/lib/smirclib.php on line 182

From what I am reading on other forums the problem is possibly that the foreach loop is empty since the array must have elements. The solution being  to add a check above the foreach loop, to count the number of elements in the array, and if it is zero, skip the foreach loop. Is this correct? Here is the code....can someone please edit it so I can see an example of how it should be done? Again total PHP newbie so please be clear if possible. Thanks so much!!!

My new host (Siteground) cloned and moved my html/php site (built by the previous owner) from Heart Internet server.

All of the site works except for the sidebar, I get these 2 errors. Anyone shed any light on these at all?
