Example :
Array
(
[0] => "example.fr", "2013-08-24", "test"
[1] => "toto.com, "2014-10-01", "test2"
)
How can I do to split this array every comma ? I would like to get every word in quotes into a variable like this :
$var1= "example.fr";
$var2= "2013-08-24";
$var3 = "test";
....
EDIT: The structure of the array is GOOD ! Every element is enclosed in quotes in ONLY one array ! Like CSV file
Don't reinvent a CSV parser, use the existing functionality.
From PHP 5.3+:
$parsed = array_map('str_getcsv', $array);
http://php.net/str_getcsv
Before 5.3:
$fh = fopen('php://temp', 'r+');
$parsed = array();
foreach ($array as $row) {
ftruncate($fh, 0);
fwrite($fh, $row);
rewind($fh);
$parsed[] = fgetcsv($fh);
}
fclose($fh);
You can use list
array("example.fr, 2013-08-24, test")
list($var1, $var2, $var3) = explode(', ', $array[0]); // or current
Unless I'm misunderstanding you, you can access the array elements and assign them to variables like this:
$var1 = $arrayName[0][0];
$var2 = $arrayName[0][1];
$var3 = $arrayName[0][2];
I can't tell from you're question if the array is holding a single string per index or if it is a 2D array. If it's holding strings then see realshadow's answer.
Use explode on every item of the array: http://www.w3schools.com/php/func_string_explode.asp
I don't think your syntax is quite right to create a multidimensional array, consider this example:
$myArray = array( array("example.fr", "2013-08-24", "test"),
array("toto.com, "2014-10-01", "test2"));
Now you have an array of arrays and can iterate over each.
If you know for sure how many items you have in each array then you can explode the array into its constituents, but if you don't know before hand than iterating will see you through.
I am not very sure with the structure, but let me know if this is what ur looking for, happy to help u then -
<?php
$myarr = array( array("example.fr", "2013-08-24", "test"),array("toto.com", "2014-10-01", "test2"));
foreach($myarr as $breakpart)
{
echo "<pre>";
print_r($breakpart);
}
OUTPUT -
Array
(
[0] => example.fr
[1] => 2013-08-24
[2] => test
)
Array
(
[0] => toto.com
[1] => 2014-10-01
[2] => test2
)

I have this dynamic multiple arrays that I need to combine in one array and serialized them. The problem is I need to keep both key and value.
$arr = array($bet_option_id => $bet_option_name);
Here i need to keep both bet_option_id AND bet_option_name. Then this result output:
Array ( [997650802] => Over 2.5 )
Array ( [997650807] => Yes )
This need to be simply
Array
(
[997650802] => Over 2.5
[997650807] => Yes
)
As it's dynamic, sometimes not comes with just single array so apparently I couldn't get it working. I need to retrieve both bet_option_id & bet_option_name. Tried something like this:
$arr = array($bet_option_id => $bet_option_name); //This is where all array keys, values are stores
$result = array();
foreach ($arr as $array) {
$result = array_merge($result, $array);
}
Any inputs will be nice.
Rather than create individual arrays like...
$arr = array($bet_option_id => $bet_option_name);
If you first create an empty array ( like you do with $result)
$arr = array();
and then add each item in using
$arr[$bet_option_id] = $bet_option_name;
Then you don't need to manipulate the array after - just create it as you want it in the first place.
You could either do like Nigel Ren suggested which is the most elegant solution
In case that you do not have arrays that their keys are entirely numeric you may use array_merge. The quote following is from PHP array-merge
Example #2 Simple array_merge() example
$array1 = array();
$array2 = array(1 => "data");
$result = array_merge($array1, $array2);
Don't forget that numeric keys will be renumbered!
Array
(
[0] => data
)
Alternatively you can always join arrays together like this
$a1 = [ 997650802 => 'Over 2.5' ];
$a2 = [ 997650807 => 'Yes' ];
var_dump( $a1 + $a2 ); // result is [997650802 => 'Over 2.5',997650807 => 'Yes']

I am trying to separate an array into two separate arrays. For example, if I have an array like this
Array([0]=>Hello[1]=>I'm[2]=>Cam)
I want to split it into two arrays and add another string
Array1([0]=>Hello[1]=>There,)
Array2([0]=>I'm[1]=>Cam)
Then finally add the two together
Array([0]=>Hello[1]=>There,[2]=>I'm[3]=>Cam)
What would be the simplest way to do this?
I know I can use array merge to put the two together but I don't know how to separate them at a certain point.
I'm also doing this on a large file that will be constantly getting bigger, so I cant use array_chunk()
Looking at your end result goal, I think a shorter method to get your desired response is to use array_splice which lets you insert into a middle of an array....
$arrayVarOriginal = array('Hello', 'Im', 'Cam');
$arrayVarExtra = array('There');
array_splice($arrayVarOriginal, 1, 0, $arrayVarExtra);
This should send you back Array([0]=>Hello[1]=>There,[2]=>Im[3]=>Cam) like you wanted!
The above avoids having to split up the array.
HOWEVER
If you did want to do it the hard way, here is how you would...
$arrayVarOriginal = array('Hello', 'Im', 'Cam');
$array1stPart = array(arrayVarOriginal[0], 'There');
$array2ndPart = array_shift($array1stPart);
$finalArray = array_merge($array1stPart, $array2ndPart);
How? array_shift removes the first item from any array, so that how we get $array2ndPart.... and $array1stPart is even easier as we can just manually build up a brand new array and take the first item from $arrayVarOriginal which is at position 0 and add 'There' in as our own new position 1.
Hope that helps :)
array_shift, array_splice, and array_merge are what you need to look into.
Based from your question, here step-by-step to get what you want for your final output.
1) Split Array
$arr = array('Hello', 'I\'m', 'Cam');
$slice = count($arr) - 1;
$arr1 = array_slice($arr, 0, -$slice);
$arr2 = array_slice($arr,1);
so, you get two new array here $arr1 and $arr2
2) Add new string
$arr1[] = "There";
3) Finally, combine the array
$arr = array_merge($arr1, $arr2)
Here sample output when you print_r the $arr
Array
(
[0] => Hello
[1] => There
[2] => I'm
[3] => Cam
)
array_slice second parameter is position where you want split. So you can do this dynamically by count the array length.
$string = array("Hello","I'm","Cam");
$firstArray = array_slice($string ,0,1);
array_push($firstArray,"There,");
$secondArray = array_slice($string ,1,2);
echo "<pre>";
print_r($firstArray);
echo "==========="."<pre>";
print_r($secondArray);
echo "<pre>";
print_r(array_merge($firstArray,$secondArray));
//out put
Array
(
[0] => Hello
[1] => There,
)
===========
Array
(
[0] => I'm
[1] => Cam
)
Array
(
[0] => Hello
[1] => There,
[2] => I'm
[3] => Cam
)
Hope it will be worked for your requirement. If not or you need more specify regarding this you can clarify your need.
I have two arrays, one is generated by using explode() on a comma separated string and the other is generated from result_array() in Codeigniter.
The results when doing print_r are:
From explode():
Array
(
[0] => keyword
[1] => test
)
From database:
Array
(
[0] => Array
(
[name] => keyword
)
[1] => Array
(
[name] => test
)
)
I need them to match up so I can use array_diff(), what's the best way to get them to match? Is there something other than result_array() in CI to get a compatible array?
You could create a new array like this:
foreach($fromDatabase as $x)
{
$arr[] = $x['name'];
}
Now, you will have two one dim arrays and you can run array_dif.
$new_array = array();
foreach ($array1 as $line) {
$new_array[] = array('name' => $line);
}
print_r($new_array);
That should work for you.
I have a csv file which has a word for each row like this
word1
word2
word3
And have the following code to read the data:
$arr = array();
$fh = fopen('path/to/file', 'r');
while (($rows = fgetcsv($fh)) !== false) {
print_r($rows);
if (!in_array($rows[0], $arr))
$arr[] = "'".trim($rows[0])."'";
}
fclose($fh);
print_r($arr);
The problem is im getting empty strings/null for $rows[0] and im quite sure the data is there.
Array ( [0] => )
Array ( [0] => )
Array ( [0] => )
Array ( [0] => '' [1] => '' [2] => '' [3] => '' )
Any help would be greatly appreciated.
You're trying to read the words into an array? Replace all that with just:
$arr = file('/path/to/file');
print_r($arr);
Cannot reproduce. I'm assuming there is something wrong with your file format. Most likely there is an empty line on top (which I'm not quite sure, but might fail the !== false test).
Better try:
$arr = array_map("str_getcsv", file("words.csv"));
print_r($arr);
And if you need to re-add the quotes, do a separate loop.
The file reading part has already been answered, but about your loop to add the quotes, you could use array_walk():
function add_quotes(&$item)
{
$item = "'" . $item . "'";
}
array_walk($arr, "add_quotes");
I have two arrays that I would like to compare and ultimately wind up with a single array with everything combined, having no duplicates. Can someone please tell me which function I should use? There are so many that it's a bit confusing.
$array1[]['name'] = 'Kim, Jones';
$array1[]['name'] = 'Jim, Miller';
array1 is an array I built that I want added to an array coming from the database. The key in the second array is also named "name". Thanks.
EDIT:
I managed to merge these two arrays but I can still see duplicates.
This is what the first array looks like:
Array
(
[0] => Array
(
[WNumber] => ADMIN
[Name] => Tim, Cooley
[Employer] => CalPERS
[Student] => 1
[Perm] => 1
[QA] => 0
[Supervisor] => 1
[RQW] => 0
)
My second array is built like this:
$add_names[]['Name']='Jim, Jones';
I just want to add $add_names to the first array WHERE there are no duplicates.
I'm tempted to sell you on CakePHP, since it has a number of functions that makes this easy in its "Set" class. Your problem is that you have the results in a nested array. A simple "array_unique" does not work in a nested array.
I'd do it the old fashioned way...
$array1[]['name'] = 'Kim, Jones';
$array1[]['name'] = 'Jim, Miller';
$array2[]['name'] = 'Kim, Jones';
$array2[]['name'] = 'Jimbo, Miller';
$array2[]['name'] = 'Jim, Jones';
$new_array=array_merge($array1, $array2);
$out_array = array();
$key_array = array();
foreach($new_array as $i => $row) {
if (empty($key_array[$row['name']])) {
$out_array[] = $row;
}
$key_array[$row['name']] = 1;
}
print_r($out_array);
This code works for me...
I think you'll need to use a combination of array_merge (adds the two arrays together) and array_unique (removes duplicate values).
$resulting_array = array_unique(array_merge($array1, $array2));
Note that array_unique will not work correctly when using multi-dimensional arrays, so if your array data looks the way you put it in your question, you'll have to think of a way around that. One of the comments on the array_unique page suggests serialize'ing all array values before running array_unique on it. Afterwards you'd just run unserialize on all array elements. Note that this can mean a performance hit if you have a big array, so you might want to consider avoiding multi-dimensional arrays in this scenario.
Something like this:
$merged_array = array_merge($array1, $array2);
$serialized_array = array_map("serialize", $merged_array);
$filtered_array = array_unique($serialized_array);
$final_array = array_map("unserialize", $filtered_array);
There isn't a direct function for handling what you are looking for in php, probably you need to write a function for it.
What I understood from your question is that you have 2 arrays :
$a = array( array( 'name' => 'Omid' ), 12 );
$b = array( array( 'name' => 'testing' ) );
and you want to merge them to get
$merge = array( array( 'name' => 'testing' ), 12 );
if that's what you want then you might want to take a look at this comment array merge recursive which leads to this code :
function array_merge_recursive_distinct ( array &$array1, array &$array2 )
{
$merged = $array1;
foreach ( $array2 as $key => &$value )
{
if ( is_array ( $value ) && isset ( $merged [$key] ) && is_array ( $merged [$key] ) )
{
$merged [$key] = array_merge_recursive_distinct ( $merged [$key], $value );
}
else
{
$merged [$key] = $value;
}
}
return $merged;
}
Does php's array_diff() do what you want?
http://us.php.net/manual/en/function.array-diff.php
or more likely array_diff_assoc:
http://us.php.net/manual/en/function.array-diff-assoc.php
Does array_diff work for you?
Description
array array_diff ( array $array1 , array $array2 [, array $ ... ] )
Compares array1 against array2 and returns the difference.
