How do I create an input argument and call the function defined below?
function insert_data ($var) {
$set_entry_array = array(
array('name' => 'name' ,'value' => $var['phone']),
array('name' => 'email' ,'value' => $var['circle']),
array('name' => 'assigned_user_id' ,'value' => 1),
);
}
I want to call this function to pass the actual value in the name and email parameter.
Your function accepts an array. You need to define the array, and pass it to the function. It appears the function expects two array keys to be set: phone and circle. We need to set them.
$myarray = array();
$myarray['phone'] = '555-1234';
$myarray['circle'] = 'foo#bar.com';
insert_data($myarray);

I have the following array:
$fields = ['field1', 'field2', 'field3'];
What I would like to do using an existing helper ('hopefully') is to convert those array string values into object key value pairs with an empty value.
This is the desired output:
$fields = (object) [
'field1' => '',
'field2' => '',
'field3' => '',
];
Is it possible to do that using a Laravel helper, so I don't have to use my own function?
You could try the following code to create a generic object.
$obj = new \stdClass();
foreach ($fields as $field) {
$obj->$field = '';
}
The reason this works is that it will iterate over each field, add set properties on the object, using the value of the array.
Note the ->$ symbol. This is because PHP will solve the $ into the value of the variable, then it will set that as the property after the arrow.
If you were to use an associative array, then you could take this a step further.
$fields = ['field1' => 'value1', 'field2' => 'value2', 'field3' => 'value3'];
foreach ($fields as $field => $value) {
$obj->$field = $value;
}

I have an array that looks like this:
And I need to translate it into this:
Some things to know about the $startArray is that it is dynamic based on the amount of people submitted on a form. Each person always has just those three fields though (custom_12, custom_13, custom_14 aka fName, lName, email). So if there were 5 members, the 5th members fName would be the key custom_12-5 in the start array.
I've been looking around on stackoverflow for a question just like this and I was not able to find one. What would be the steps taken and possible array functions or anything else for creating the $endArray ?
There's actually a builtin function for this: https://www.php.net/manual/en/function.array-chunk.php
For example, array_chunk($startArray, 3) will give you the base for your new array, you'll just need to then iterate through it and rename the keys.
Alternatively, just iterate through the array yourself and add the values to a new array depending on the index of the current iteration.
Thanks to Charlie's advice, I came up with this.
$startArray = array(
'custom_12' => 'john',
'custom_13' => 'johny',
'custom_14' => 'john#johny.com',
'custom_12-2' => 'bob',
'custom_13-2' => 'bobby',
'custom_14-2' => 'bob#bobby.com',
'custom_12-3' => 'don',
'custom_13-3' => 'donny',
'custom_14-3' => 'don#donny.com'
);
$middleArray = array_chunk($startArray, 3);
$endArray = array_map(function($val) {
return array(
'fName' => $val[0],
'lName' => $val[1],
'email' => $val[2]
);
}, $middleArray);
echo "<pre>";
print_r($endArray);
echo "</pre>";
And the output is exactly what I wanted:

I have an array with following elements:
$arr = array(
'nick' => "blabla",
'pass => "blabla2"'
);
I would like to convert it somehow to strings, the first string would be the value of nick - "blabla", the second string would be the value of pass - "blabla2"
Thank you.
If you want to convert elements of the array to separate string variables you can use extract function to import elements from an array to variables. For example:
$arr = array(
'nick' => "blabla",
'pass' => "blabla2"
);
extract($arr);
echo $nick, ' ', $pass;
$arr = [
'nick' => "blabla",
'pass' => "blabla2"
];
$string_one=$arr['nick'];
$string_two=$arr['pass'];

I am new at PHP and struggling with given problem.
I have to write a function winner_generator($parameter, $random) that would pick and show random name from given array:
<p><?php echo winner_generator(array(
array('name' => 'Bob'),
array('name' => 'Donald'),
array('name' => 'Peter'),
array('name' => 'Nick')
),rand()); ?></p>
Any ideas on how I should start solving this problem? Many thanks for all your help, looking forward.
So the idea is generating a random number between 0 and the length of the array - 1 (because the index of an array starts at 0). Then you pick the candidate at whatever number the random returns. As you want to echo the winner you need to select the 'name' key from the candidate array.
<?php
function winner_generator(array $candidates){
$rand = rand(0, sizeof($candidates)-1);
return($candidates[$rand]['name']);
}
echo winner_generator(array(
array('name' => 'Bob'),
array('name' => 'Donald'),
array('name' => 'Peter'),
array('name' => 'Nick')
));

Hi I need to generate json code with php like this http://api.androidhive.info/contacts/
You are looking for json_encode(). Passing an associative array to it will return a JSON representation.
http://us1.php.net/json_encode
You can use an multi-dimensional array with the json_encode function to achieve this structure.
$var = array(
"contacts" => array (
array(
"id" => 1,
"name" => "foo"
),
array(
"id" => 2,
"name" => "bar"
)
)
);
echo json_encode($var);
