So lets say I have an array and when I var_dump(); it, it has the following output:
[1]=>
string(20) "Name: Kevin"
[2]=>
string(20) "Age: 20"
Can I manipulate it using implode or explode so that the output would look like this:
[Name]=>
string(5) "Kevin"
[Age]=>
string(2) "20"
Any help would be appreciated.
You can use explode() with trim()
$array = [];
foreach($initialArray as $data){
$exploded = explode(':',$data);
$array[trim($exploded[0])] = trim($exploded[1]);
}

I'm having trouble using explode() in php.
I want to make an array of strings from the $_GET super global array.
The url will be like:
example/myproject.php?keywords=this+is+an+example
I want an array of the keywords so it should be like this:
myArray(6) = { [0]=> string(4) "this"
[1]=> string(2) "is"
[2]=> string(2) "an"
[3]=> string(7) "example" }
Here's my code:
$stringVals = explode("+",($_GET['keywords']));
var_dump($stringVals);
Here's the output:
array(1) { [0]=> string(30) "this is an example of a string" }
An example that works:
$pizza = "piece1 piece2 piece3 piece4 piece5 piece6";
$pieces = explode(" ", $pizza);
var_dump($pieces);
The output of this:
array(6) { [0]=> string(6) "piece1" [1]=> string(6) "piece2" [2]=>
string(6) "piece3" [3]=> string(6) "piece4" [4]=> string(6) "piece5"
[5]=> string(6) "piece6" }
I want the words from $_GET like that..
The "+" sign you see is actually just an encoded space. Therefore, you can split it normally using a space.
explode(' ', $_GET['keywords']);
Make sure you sanitize it if you're going to put it in a database.
Actually you can simply use:
explode(" ", $_GET['string'])
The + sign in the url actually means a space, not plus :- )
It's because spaces aren't allowed in the urls (url cannot have whitespaces), so it's actually converted to a plus sign.
In a normal GET request, the + in the URL will be converted back to spaces by the web server, so you should be exploding on ' '.
$stringVars = explode(' ', $_GET['keywords']);
See https://stackoverflow.com/a/2678602/1331451 for an explanation of why that is the case.
$myarray = explode(" ", $_GET['keywords']);
var_dump($myArray);
How's that?
Don't use plus symbol because The "+" sign you see is actually just an encoded space. use comma in URL while passing values from one page to another page here is solution after sending them in URL using comma separated form :-
$myArray = explode(',', $_REQUEST['keywords']);
after this you can get your data as following
$myArray[0]=this;
$myArray[1]=is;
$myArray[2]=an;
$myArray[3]=example;
$url = 'example/myproject.php?keywords=this+is+an+example';
$x = parse_url($url);
$y = str_replace("keywords=", "", $x["query"]);
var_dump(explode("+", $y));
First parse the url, second remove keywords=, next explode what's left by + sign.
This might seem trivial but it's hurting my head. Can someone explain the reason
The http://php.net/manual/es/function.explode.php examples show (which I have trimmed).
$pizza = "piece1 piece2 piece3"; // string
$pieces = explode(" ", $pizza);
// after a var dump
array(3) { [0]=> string(6) "piece1"
[1]=> string(6) "piece2"
[2]=> string(6) "piece3" }
This works lovely, removes all the spaces and does a nice little array to work with, however when I use something similar shown below
$path = "/test-gallery/2/"; // string
$urlpieces = explode("/", $path);
// after a var dump
array(4) { [0]=> string(0) ""
[1]=> string(12) "test-gallery"
[2]=> string(1) "2"
[3]=> string(0) "" }
I get the first and last with an empty string. Why does it not remove the first and the last array elements? I can always add another step and remove it but the explode should take it all out shouldnt it?
Thanks for the advice in advance.

No. that is how explode works. Delimiter is at both end so "" string was found at both the ends after exploding
I have a block of text and a preg_match_all sequence to create an array ($matches) from certain elements in the text.
I then look up a corresponding entry for each string in the first array using mysqli and receive a second array - ($replacement).
I want to replace the first array's position in the original text with the second array, re-finding the first array and naming it $arraytoreplace. This is the code I use:
$replacement = array();
$myq = "SELECT code,title FROM messages WHERE ID=?";
if ($stmt = $mysqli2->prepare($myq)) {
foreach($matches[1] as $value) {
$stmt->bind_param("s", $value);
$stmt->execute();
// bind result variables
$stmt->bind_result($d,$cc);
if($stmt->fetch()) {
$replacement[] = '' . $cc . '';
}
}
$stmt->close();
}
If I use var_dump on the arrays before the str_replace like so:
var_dump($arraytoreplace);
var_dump($replacement);
I get:
array(4) {
[0]=> string(3) "111"
[1]=> string(2) "12"
[2]=> string(4) "1234"
[3]=> string(1) "0"
}
array(4) {
[0]=> string(5) "hello"
[1]=> string(2) "hi"
[2]=> string(3) "foo"
[3]=> string(3) "bar"
}
I then use str_replace to drop the second array into the first array's place in the original text.
Usually this is fine, but everything breaks once it hits the 10 string in an array mark.
Instead of Text hello text hi I'll get Text 11foo text foo1 or something equally bizarre.
Any ideas?
Edit: The code used for replacing the arrays as follows:
$messageprep = str_replace($arraytoreplace, $replacement, $messagebody);
$messagepostprep = str_replace('#', '', $messageprep);
echo '<div class="messagebody">' . $messagepostprep . '</div>';
It looks like your getting partial replacements when a string of numbers is contained inside a longer string, i.e. 23 inside 1234.
You need to do your replacements with a regular expression on the boundary of the search string. Something like...
$text = preg_replace("/\b" . $replace . "\b/", $value, $text);
Another possible solution would be to consider changing the values to replace so that they are padded with zeros...
Array(
[0] => string(3) "0111"
[1] => string(2) "0012"
[2] => string(4) "1234"
[3] => string(1) "0000"
)
...and make sure that your search strings are also padded with zeros, because 0012 will never be confused with 12 and accidentally found in 0123.
My string is :
$mystring = "https://maps.google.com/?ll=37.0625,-95.677068&spn=37.188995,86.572266&t=m&z=4";
Now I want those values which I have marked as bold from the string. How can I achieve this with PHP?
Use the following functions parse_url and parse_str. You could do something like this the following
$url = "https://maps.google.com/?ll=**37.0625,-95.677068**&spn=**37.188995,86.572266**&t=m&z=4";
$parts = parse_url($url);
if(isset($parts['query'])) {
parse_str(urldecode($parts['query']), $result);
print_r($result)
}
use explode or parse_url or parse_str
you'll have to use $_GET['ll'] and $_GET['spn'] to repectively obtain 37.0625,-95.677068 and 37.188995,86.572266
Here regular expression will be most efficient to parse your required values.
$url = "https://maps.google.com/?ll=37.0625,-95.677068&spn=37.188995,86.572266&t=m&z=4";
$regex = "/[-]*\d+.\d*/";
preg_match_all($regex,$url,$out, PREG_PATTERN_ORDER);
// $out = array(1) { [0]=> array(4) { [0]=> string(7) "37.0625" [1]=> string(10) "-95.677068" [2]=> string(9) "37.188995" [3]=> string(9) "86.572266" } }
I have this $str value :
[{\"firstname\":\"guest1\",\"lastname\":\"one\",\"age\":\"22\",\"gender\":\"Male\"},{\"firstname\":\"guest2\",\"lastname\":\"two\",\"age\":\"22\",\"gender\":\"Female\"}]
I want to split it into the following:
firstname:guest1,lastname:one,age:22
firstname:guest2,lastname:two,age:22
I tried explode (",",$str) , but it explode all using , as delimiter and I don't get what I want
anyone can help me ?
As Josh K points out, that looks suspiciously like a JSON string. Maybe you should do a json_decode() on it to get the actual data you're looking for, all organized nicely into an array of objects.
EDIT: it seems your string is itself wrapped in double quotes ", so you'll have to trim those away before you'll be able to decode it as valid JSON:
$str_json = trim($str, '"');
$guests = json_decode($str_json);
var_dump($guests);
I get this output with the var_dump(), so it's definitely valid JSON here:
array(2) {
[0]=>
object(stdClass)#1 (4) {
["firstname"]=>
string(6) "guest1"
["lastname"]=>
string(3) "one"
["age"]=>
string(2) "22"
["gender"]=>
string(4) "Male"
}
[1]=>
object(stdClass)#2 (4) {
["firstname"]=>
string(6) "guest2"
["lastname"]=>
string(3) "two"
["age"]=>
string(2) "22"
["gender"]=>
string(6) "Female"
}
}
JSON (JavaScript Object Notation) is not CSV (comma-separated values). They're two vastly different data formats, so you can't parse one like the other.
To get your two strings, use a loop to get the keys and values of each object, and then build the strings with those values:
foreach ($guests as $guest) {
$s = array();
foreach ($guest as $k => $v) {
if ($k == 'gender') break;
$s[] = "$k:$v";
}
echo implode(',', $s) . "\n";
}
Output:
firstname:guest1,lastname:one,age:22
firstname:guest2,lastname:two,age:22
(Assuming you do want to exclude the genders for whatever reason; if not, delete the if ($k == 'gender') break; line.)
If you split on ,'s then you will get all the other crap that surrounds it. You would then have to strip that off.
Looks a lot like JSON data to me, where is this string coming from?
If that is valid json, just run it through json_decode() to get a native php array...
Note that you may need to run it through stripslashes() first, as it appears you may have magic_quotes_gpc set... You can conditionally call it by checking with the function get_magic_quotes_gpc:
if (get_magic_quotes_gpc()) {
$_POST['foo'] = stripslashes($_POST['foo']);
}
$array = json_decode($_POST['foo']);
You need to use preg_replace function.
$ptn = "/,\\"gender\\":\\"\w+\\"\}\]?|\\"|\[?\{/";
$str = "[{\"firstname\":\"guest1\",\"lastname\":\"one\",\"age\":\"22\",\"gender\":\"Male\"},{\"firstname\":\"guest2\",\"lastname\":\"two\",\"age\":\"22\",\"gender\":\"Female\"}]";
$rpltxt = "";
echo preg_replace($ptn, $rpltxt, $str);
You can the php regular expression tester to test the result.
or use preg_match_all
$ptn = "/(firstname)\\":\\"(\w+)\\",\\"(lastname)\\":\\"(\w+)\\",\\"(age)\\":\\"(\d+)/";
$str = "[{\"firstname\":\"guest1\",\"lastname\":\"one\",\"age\":\"22\",\"gender\":\"Male\"},{\"firstname\":\"guest2\",\"lastname\":\"two\",\"age\":\"22\",\"gender\":\"Female\"}]";
preg_match_all($ptn, $str, $matches);
print_r($matches);
i still haven't get a chance to retrieve the JSON :
I var_dump the trimmed value as :
$str_json = trim($userdetails->other_guests, '"');
$guests = json_decode($str_json);
var_dump($str_json,$guests);
WHERE $userdetails->other_guests is the $str value I had before...
I get the following output :
string(169) "[{\"firstname\":\"guest1\",\"lastname\":\"one\",\"age\":\"22\",\"gender\":\"Male\"},{\"firstname\":\"guest2\",\"lastname\":\"two\",\"age\":\"23\",\"gender\":\"Female\"}]"
NULL
This mean the decoded json are NULL... strange
