PHP - How To Use Variable Variables Of Object?
I know how to use $$ and ${} to use variable variables, but how would I get the same functionality out of a variable that is storing an object name?
I have a function that is passed the name of an array of objects. As you can guess, that name will change based on which portion of the program is calling the function. How would I use variable variables of objects in this instance? Would it just be: Code: [Select] $this->${$objArrayName}->threadName = etc; ? To make sure I'm not being misunderstood, I have 3 arrays of objects (replies, mainThreads, and stickies) and depending on which name I pass the function, I want it to use $this->replies OR $this->mainThreads OR $this->stickies to apply properties of those objects to. Thanks for any help. -Adam Similar Tutorialsdoes anyone know how to decode this XML variable value into string values? I also need to know the oposite way: creating variable values into xml. I've tried several code examples but they did filter the requested data.

But when I try the same method using a session variable (Test 1) the if statement is not executed. Please could you tell me why the if statement in Test 1 is not being executed? Code: [Select] <?php # TEST 1 $_SESSION[test_variable] = "abcd"; $session_variable_name = "_SESSION[test_variable]"; if ($$session_variable_name == "abcd") { echo "<br>line 373, abcd<br>"; } # TEST 2 $test_variable = "efgh"; $test_variable_name = "test_variable"; if ($$test_variable_name == "efgh") { echo "<br>line 379, efgh<br>"; } ?> Many thanks, Stu Can someone explain to me how this is done? Is it good practice to put an oop object in session variable
<?php
global $places;
$comm = $GLOBALS["location"];
$comm=trim($comm);
while(list($one,$two) = each($places))
{
echo "<option value=\"$two\"";

Server returns a json object and i want to save it in aR variable.
But console.log($aR); returns undefined
Any idea on how to fix it ?I am not sure how to do the below, would variable variables be the way -- those are a new and confusing thing for me :-/ i have an array: $contactData = array('admin_firstName' => 'John', 'admin_lastName' => 'Smith', 'user_firstName' => 'Betty', user_lastName => 'Jones'); I have a function that little function that looks like this: function compare($contactSet, $var, $value){ global $contactData; $key = $contactData . "['" . $contactSet . "_" . $var ."']"; //above doesnt work, but you can see how the array key is constructed if ($key == $value) { // So, if the array key varied it would look like: // if ($contactData['admin_firstName'] == $value echo "same"; } else { echo "different"; } } and then I want to call it like this: compare('admin', 'firstName', 'John'); //would echo "same"; Any help is greatly appreciated. I have often wanted to use variable variables, or whatever this would be called, but don't know to pull it off. I can add another example if this wasnt clear enough. I need to use a variable variable. I need: $row['pos_1'] $row['pos_2'] to use $i for the numbers I have this: if ($row{[pos_.$i]} == 'ad') which is throwing an error Quote Parse error: syntax error, unexpected '[' Any ideas? Thanks! Could someone help me crack this issue. I am trying to insert a variable into an flash object echo string's src. I've try many variations but can't figure it out. Below is the code. cheers ray <?php $var = 'map.swf'; echo ' <OBJECT ID="map" CLASSID="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" CODEBASE="http://active.macromedia.com/flash2/cabs/swflash.cab#version=2,0,0,0" WIDTH="50%" HEIGHT="50%"> <PARAM NAME="Movie" VALUE="map.swf"> <PARAM NAME="Play" VALUE="false"> <PARAM NAME="Quality" VALUE="best"> <PARAM NAME="swLiveConnect" VALUE="true"> <PARAM NAME="loop" VALUE="false"> <EMBED NAME="slav" SRC=" map.swf " swLiveConnect="true" WIDTH="50%" HEIGHT="50%" mayscript="mayscript" quality="best" play="false" LOOP="false" pluginspage="http://www.macromedia.com/shockwave/download/index.cgi?P1_Prod_Version=ShockwaveFlash2"> </EMBED> </OBJECT>'; echo "<br/>"; echo $var; echo "<br/>"; ?> Goal <?php $var = 'map.swf'; echo ' <OBJECT ID="map" CLASSID="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" CODEBASE="http://active.macromedia.com/flash2/cabs/swflash.cab#version=2,0,0,0" WIDTH="50%" HEIGHT="50%"> <PARAM NAME="Movie" VALUE=" $var "> <PARAM NAME="Play" VALUE="false"> <PARAM NAME="Quality" VALUE="best"> <PARAM NAME="swLiveConnect" VALUE="true"> <PARAM NAME="loop" VALUE="false"> <EMBED NAME="slav" SRC=" $var " swLiveConnect="true" WIDTH="50%" HEIGHT="50%" mayscript="mayscript" quality="best" play="false" LOOP="false" pluginspage="http://www.macromedia.com/shockwave/download/index.cgi?P1_Prod_Version=ShockwaveFlash2"> </EMBED> </OBJECT>'; ?> If I knew what to call it I could have searched it. So I will just explain. I have a form that is pulling from a database to build the following. echo <input name='$row[id]' type='text' id='$row[id]' size=2>; This will build a page that has this <input name='22' type='text' id='22' size=2> <input name='54' type='text' id='54' size=2> This part works great. The problem is when I try to add it to the database. How can I insert variables that I don't know the names of? They will be something like $_POST[22] $_POST[54] and so on. I hope someone can understand my jibberish. I am sure there is a WAY better way to do this. Is it possible to split a variable into 2 variables? /// I have this sentence $item = "Below Telegraph Hill, Smallwork Canvas Edition"; /// And I want to be able to do this $item = "Below Telegraph Hill" ; $medium = "Smallwork Canvas Edition"; Is it possible to find the comma in a string, and remove the comma & everything before or after it? Any recommendations would be appreciated. I've been trying for days to get this simple 1990's code to work. It won't work. Now, I don't even want to get it to work, because it's crappy ugly 1990's code... Is there an elegant way to accomplish this? (I just want to be able to manually override the default catalog prices as needed.)
<?php
//default catalog prices:
$sku = "123456";
$price = "5.99";
if(isset($_POST[$sku])) { // if form submitted, and
if( ${$_POST[$sku]} != $price) { //...and I manually changed price
$price = ${$_POST[$sku]}; //...then change price to what I input
}
}
echo '<form name="form1" method="post" action="Crappy1990sCodePage.php">';
echo '<input type="text" name="'.$sku.'" value="'.$price.'">';
echo '<input type="text" name="'.$sku.'" value="'.$price.'">';// (same sku may be listed twice)
echo '<input type="submit" class="no_class_its_the_90s_remember">'
echo '</form>';
?>
Thank you 😀 Edited July 25, 2020 by StevenOliverQuestion about variable variables and using session variables for them. O.K. So if I have: $foo = 3; $_SESSION['bar'] = "foo"; $$_SESSION['bar'] should equal the value of $foo, however I can't get it to work. Can someone tell me what I am doing wrong..... is it formatting??? Thanks, Thomas Hello, I have the situation shown below in the code:
if(//condition is met)
{ $val = new Val();
$valon = $val->check($_POST, array(.........));
}
if($valon->passes())
{ $use = new Use();
........
}
//check() and passes() both belong to class Val
public function check($source, $items = array())
{ ......................
return $this;
}
I get the following warning and error:Notice: Undefined variable: valon and Fatal error: Call to a member function passes() on a non-object I can't see anything wrong with the code. check() returns an object of class Val which is assigned to $valon, $valon then calls a member function of class Val. Could you please help. Please let me know whether to include further code. I'm not versed in PHP OOP and I have some code that I need to echo out onto a page. I don't know what the meaning of $ct->something is in this code. Is this an array of some type? How do I echo out the $ct->title onto another page? Use a function call?
