PHP replace wildcards (%s, %d) in string with vars
(2 answers)
Closed 3 years ago.
I've got a JSON file which looks like this
{
"facebook": {
"icon": "fab fa-facebook",
"title": "Facebook",
"url": "https://facebook.com/%s"
},
"instagram": {
"icon": "fab fa-instagram",
"title": "Instagram",
"url": "https://instagram.com/%s"
}
}
So I'm getting users social links from a form, but only the user's ID of social link eg.https://facebook.com/ID. I'm storing the users ID in JSON file in database. I'm using PHP. How do I add the users ID in that '%s' and display the link.
To put together the information using the JSON data you have, you would use either sprintf() or printf() (the only difference being the printf() directly outputs the data sprintf() returns a string). The information on the manual pages shows how things like %s works.
So the code would look something like...
$id = 123;
$userName = "User name";
$json = '{
"facebook": {
"icon": "fab fa-facebook",
"title": "Facebook",
"url": "https://facebook.com/%s"
},
"instagram": {
"icon": "fab fa-instagram",
"title": "Instagram",
"url": "https://instagram.com/%s"
}
}';
$socialMedia = json_decode( $json, true );
echo echo '<a href="'.sprintf($socialMedia["facebook"]["url"], $id).'">'.
$userName.'</a>';
Which outputs...
User name
For example. I want to get coordinates of all node buildings in bbox.
PHP
$queryBuildings="[out:json];node['building']({$y1},{$x1},{$y2},{$x2});out;";
$data = file_get_contents("http://overpass-api.de/api/interpreter?data={$queryBuildings}")
One element from result:
{
"type": "node",
"id": 29537155,
"lat": 54.6744568,
"lon": -2.1421066,
"tags": {
"building": "house",
"description": "Abandoned (2007). Associate with lead mine workings above it?",
"name": "Flushiemere House"
}
}
I want to get only lon and lat fields it's possible?
You can use skeleton print mode (out skel) which omits all tags, thus being slightly shorter. So your request should become: [out:json];node['building']({$y1},{$x1},{$y2},{$x2});out skel;
Currently csv output mode ([out:csv]) is the only mode where you can select the fields to be shown.
<?php
$data = '{
"type": "node",
"id": 29537155,
"lat": 54.6744568,
"lon": -2.1421066,
"tags": {
"building": "house",
"description": "Abandoned (2007). Associate with lead mine workings above it?",
"name": "Flushiemere House"
}
}';
$test = json_decode($data);
var_dump($test->lon);
First use json_decode to parse the response body:
$parsed_data = json_decode($data);
Then you can access the various fields like so:
$lat = $parsed_data->lat;
$lon = $parsed_data->lon;
I have a JSON array like this:
[
{
"title": " Bones of the Hills (Conqueror #3) ",
"author": "Conn Iggulden",
"format": "Hardcover",
"pages": "518",
"rating": "4.29",
"image": "http://d.gr-assets.com/books/1347616868l/3276637.jpg"
}
]
Sometimes, (not always) the title string has a link in it. How can I remove the link and everything in it? I don't even want the text inside the anchor. I want to end up with JUST "Bones of the Hills" as the title. How can I do this in php? I have googled loads, but nothing seemed to work.
You can use php built in function strip_tags() on title, it will remove all html elements from title including link
You can use strip_tag() function to avoid this error
$str='[{"title": " Bones of the Hills (Conqueror #3) ","author": "Conn Iggulden","format": "Hardcover",';
$str.='"pages": "518","rating": "4.29","image": "http://d.gr-assets.com/books/1347616868l/3276637.jpg"}]';
echo $str2=strip_tags($str);
$array=json_decode($str2);
print_r($array);
first of all your json array is incorrect , check this
[
{
"title": " "title": " Bones of the Hills (Conqueror #3) ",
"author": "Conn Iggulden",
"format": "Hardcover",
"pages": "518",
"rating": "4.29",
"image": "http://d.gr-assets.com/books/1347616868l/3276637.jpg"
}
]
use "title": " Bones of the Hills (Conqueror #3) "
instead of
<a href="/series/44108-conqueror" class="greyText"
then
$arr = json_decode($json,true);
$arr['title'] = preg_replace("/<a.+?href.+?>.+?<\/a>/is","",$arr['title']);
var_dump($arr['title']);
now your title will be
string(20) " Bones of the Hills "
I'm trying to match a form supplied UTC time and form supplied event name string with an array read in from a file. The problem is that it seems to always match even when it shouldn't. The format of the file will always be constant, so I know I'll be looking for a value within double quotes, so after failing to get results with strpos(), I tried preg_match...and now match everything. Code and example output follow ($utc and $event_name)are already set and correct when we get here):
$match1 = "/\"{$utc}\"/";
$match2 = "/\"{$event_name}\"/";
print "Match Values: $match1, $match2<p>";
foreach($line_array as $key => $value) {
print "Value = $value<p>";
if ((preg_match($match1,$value) == 1) and (preg_match($match2,$value) == 1))
{
print "Case 1 - False<p>";
} else {
print "Contains targets: $value<p>";
//code to act on hit will go here
}
}
And here's what comes back:
Match Values: /"1371033000000"/, /"Another test - MkII "/
Value = { "date": "1357999200000", "type": "meeting", "title": "Plant and Animal Genome Conference, San Diego, CA", "description": "NCGAS to present at Plant and Animal Genome Conference, San Diego, CA", "url": "http://www.event1.com/" }
Contains targets: { "date": "1357999200000", "type": "meeting", "title": "Plant and Animal Genome Conference, San Diego, CA", "description": "NCGAS to present at Plant and Animal Genome Conference, San Diego, CA", "url": "http://www.event1.com/" }
Value = { "date": "1357693200000", "type": "meeting", "title": "Testing Addition", "description": "This is a fake event.", "url": "http://pti.iu.edu" }
Contains targets: { "date": "1357693200000", "type": "meeting", "title": "Testing Addition", "description": "This is a fake event.", "url": "http://pti.iu.edu" }
Value = { "date": "1371033000000", "type": "meeting", "title": "Another test - MkII", "description": "This is a fake event.", "url": "http://pti.iu.edu" }
Contains targets: { "date": "1371033000000", "type": "meeting", "title": "Another test - MkII", "description": "This is a fake event.", "url": "http://pti.iu.edu" }
I should only be matching the last one, but they all match. I've been playing with the regex and can't seem to find the right magic.
Simplified it and got what I was after:
foreach($line_array as $key => $value) {
print "Value = $value<p>";
if (preg_match("/$utc/",$value) and preg_match("/$event_time/",$value))
{
print "Contains targets: $value<p>";
} else {
print "Case 1 - False<p>";
//code to act on hit will go here
}
}
But answer 2 got me in the right direction. Thanks, Ian!
You don't need to do anything weird inside a double-quoted string, just drop your variable in as is...
$match1 = "/$utc/";
$match2 = "/$event_name/";
I suspect your regexes are looking for zero-length strings.
Also, this line doesn't need so many parentheses...
if (preg_match($match1,$value) == 1 and preg_match($match2,$value) == 1) {
[...]
}

Then, I have a foreach statement which adds the data to a MYSQL database:
foreach($result as $key => $value) {
if($value) {
mysql_query("INSERT INTO `games_db`.`Games` (`title`, `description`, `image`, `category`, `page`, `rating`, `width`, `height`, `tags`) VALUES ('$value->name', '$value->description', '/images/$pageid.jpg', '$category', '$pageid', '$value->rating', '$value->width', '$value->height', '$value->tags')")
}
My question is, What do I have to do to show and insert the tags from the JSON file? Currently, When I run this page, the data for the "tags" column just says "Array".
You can use json_decode() as so:

$jsonObject = json_decode($jsonString);
foreach ($jsonObject->tags as $tag) {
echo $tag . PHP_EOL;
//Do something
}
If you use less than PHP 5.2.0, you can use the JSON PECL Extension
I should also add that you shouldn't use the mysql functions any more - they're deprecated. See: Why shouldn't I use mysql_* functions in PHP?
use json_decode():
json_decode — Decodes a JSON string
$jsonObject = json_decode($string); // returns an object
or:
$jsonArray = json_decode($string, true); // if second argument is true, returned object will be converted to an associative array
Edit:
as suggested by #nickhar: NOTE: You need PHP 5.2.0 or above to use json_decode()
Or one of the emulations floating around – #mario
