Take a look at this code:
$GET = array(); $key = 'one=1'; $rule = explode('=', $key); /* array_push($GET, $rule[0] => $rule[1]); */ I'm looking for something like this so that:
print_r($GET); /* output: $GET[one => 1, two => 2, ...] */ Is there a function to do this? (because array_push won't work this way)
Nope, there is no array_push() equivalent for associative arrays because there is no way determine the next key.
You'll have to use
$arrayname[indexname] = $value; Pushing a value into an array automatically creates a numeric key for it.
When adding a key-value pair to an array, you already have the key, you don't need one to be created for you. Pushing a key into an array doesn't make sense. You can only set the value of the specific key in the array.
// no key array_push($array, $value); // same as: $array[] = $value; // key already known $array[$key] = $value; You can use the union operator (+) to combine arrays and keep the keys of the added array. For example:
<?php $arr1 = array('foo' => 'bar'); $arr2 = array('baz' => 'bof'); $arr3 = $arr1 + $arr2; print_r($arr3); // prints: // array( // 'foo' => 'bar', // 'baz' => 'bof', // ); So you could do $_GET += array('one' => 1);.
There's more info on the usage of the union operator vs array_merge in the documentation at http://php.net/manual/en/function.array-merge.php.
Exactly what Pekka said...
Alternatively, you can probably use array_merge like this if you wanted:
array_merge($_GET, array($rule[0] => $rule[1])); But I'd prefer Pekka's method probably as it is much simpler.
I would like to add my answer to the table and here it is :
//connect to db ...etc $result_product = /*your mysql query here*/ $array_product = array(); $i = 0; foreach ($result_product as $row_product) { $array_product [$i]["id"]= $row_product->id; $array_product [$i]["name"]= $row_product->name; $i++; } //you can encode the array to json if you want to send it to an ajax call $json_product = json_encode($array_product); echo($json_product); hope that this will help somebody
I was just looking for the same thing and I realized that, once again, my thinking is different because I am old school. I go all the way back to BASIC and PERL and sometimes I forget how easy things really are in PHP.
I just made this function to take all settings from the database where their are 3 columns. setkey, item (key) & value (value) and place them into an array called settings using the same key/value without using push just like above.
Pretty easy & simple really
// Get All Settings $settings=getGlobalSettings(); // Apply User Theme Choice $theme_choice = $settings['theme']; .. etc etc etc .... function getGlobalSettings(){ $dbc = mysqli_connect(wds_db_host, wds_db_user, wds_db_pass) or die("MySQL Error: " . mysqli_error()); mysqli_select_db($dbc, wds_db_name) or die("MySQL Error: " . mysqli_error()); $MySQL = "SELECT * FROM systemSettings"; $result = mysqli_query($dbc, $MySQL); while($row = mysqli_fetch_array($result)) { $settings[$row['item']] = $row['value']; // NO NEED FOR PUSH } mysqli_close($dbc); return $settings; } So like the other posts explain... In php there is no need to "PUSH" an array when you are using
Key => Value
AND... There is no need to define the array first either.
$array=array();
Don't need to define or push. Just assign $array[$key] = $value; It is automatically a push and a declaration at the same time.
I must add that for security reasons, (P)oor (H)elpless (P)rotection, I means Programming for Dummies, I mean PHP.... hehehe I suggest that you only use this concept for what I intended. Any other method could be a security risk. There, made my disclaimer!
This is the solution that may useful for u
Class Form { # Declare the input as property private $Input = []; # Then push the array to it public function addTextField($class,$id){ $this->Input ['type'][] = 'text'; $this->Input ['class'][] = $class; $this->Input ['id'][] = $id; } } $form = new Form(); $form->addTextField('myclass1','myid1'); $form->addTextField('myclass2','myid2'); $form->addTextField('myclass3','myid3'); array (size=3) 'type' => array (size=3) 0 => string 'text' (length=4) 1 => string 'text' (length=4) 2 => string 'text' (length=4) 'class' => array (size=3) 0 => string 'myclass1' (length=8) 1 => string 'myclass2' (length=8) 2 => string 'myclass3' (length=8) 'id' => array (size=3) 0 => string 'myid1' (length=5) 1 => string 'myid2' (length=5) 2 => string 'myid3' (length=5) A bit weird, but this worked for me
$array1 = array("Post Slider", "Post Slider Wide", "Post Slider"); $array2 = array("Tools Sliders", "Tools Sliders", "modules-test"); $array3 = array(); $count = count($array1); for($x = 0; $x < $count; $x++){ $array3[$array1[$x].$x] = $array2[$x]; } foreach($array3 as $key => $value){ $output_key = substr($key, 0, -1); $output_value = $value; echo $output_key.": ".$output_value."<br>"; } A bit late but if you don't mind a nested array you could take this approach:
$main_array = array(); //Your array that you want to push the value into $value = 10; //The value you want to push into $main_array array_push($main_array, array('Key' => $value)); To clarify, if you output json_encode($main_array) that will look like [{"Key":"10"}]
$arr = array("key1"=>"value1", "key2"=>"value"); print_r($arr); // prints array['key1'=>"value1", 'key2'=>"value2"]
array_push($arr, ['key1' => $value1, 'key2' => value2]); This works just fine. creates the the key with its value in the array
I wonder why the most simpliest method hasn't been posted yet:
$arr = ['company' => 'Apple', 'product' => 'iPhone']; $arr += ['version' => 8]; It's the same like merging two arrays together with array_merge.
hi i had same problem i find this solution you should use two arrays then combine them both
<?php $fname=array("Peter","Ben","Joe"); $age=array("35","37","43"); $c=array_combine($fname,$age); print_r($c); ?> reference : w3schools
The simple way:
$GET = array(); $key = 'one=1'; parse_str($key, $GET); array_push($GET, $GET['one']=1);
works for me
Example array_merge()....
$array1 = array("color" => "red", 2, 4); $array2 = array("a", "b", "color" => "green", "shape" => "trapezoid", 4); $result = array_merge($array1, $array2); print_r($result);
Array([color] => green,[0] => 2,[1] => 4,[2] => a,[3] => b,[shape] => trapezoid,[4] => 4,)
