In my MySQL table I have a column with name "datei". For now each field contains a path - e.g. fileadmin/media/pdf/AGB.pdf
This is how my PHP looks like:
$Inhalt .= '<div class="DLB_Download_Zeile">
<a href="'.$Downloads->datei.'" target="_blank">
<div class="DLB_Download_Zeile_Bild"><img src="fileadmin/media/images/pdficon.png" width="30" alt="PDF Icon"></div>
<div class="DLB_Download_Zeile_Link">'.$Downloads->dateiname.'</div>
</a>
</div>';
I would now like to set the databse field to: fileadmin/media/pdf/AGB.pdf;fileadmin/media/pdf/anotherPDF.pdf;fileadmin/media/pdf/anotherFile.pdf
That mean in PHP I would need to run a loop that generates the same HTML for each path separated by the semicolon. How can I do this?
It would be possible to do using this:
$string = 'fileadmin/media/pdf/AGB.pdf;fileadmin/media/pdf/anotherPDF.pdf;fileadmin/media/pdf/anotherFile.pdf';
$paths = explode(';', $string);
foreach ($paths as $path) {
//Your code here
}
The explode() will split the sting at the semicolon's.
This can also be reversed to get a string again to put it in the database.
$string = implode(';', $paths);
You can try this :
$value = 'fileadmin/media/pdf/AGB.pdf;fileadmin/media/pdf/anotherPDF.pdf;fileadmin/media/pdf/anotherFile.pdf';
$array = explode(';', $value);
foreach ($array as $key => $value) {
echo $value;
}

I have a xml with more subcategory.
I want extract in Php the “long_name” where type is “adminkstrative_area_level_3”
How I can do?
This is my xml https://ibb.co/fY27bJ
I tried but don’t work
<?
$string_data = "https://maps.googleapis.com/maps/api/geocode/xml?latlng=41.51,15.16&key=AIzaSyClG_vc2nkQCzXqvDzW1maPrUWLyADI7xI";
$xml = simplexml_load_string($string_data);
$citta = (string) $xml->result[0]->address_component[3]->long_name;
echo "<p>".$citta."</p>";
?>
You are missing geoname in $xml-> name;
Try it like this:
$xml = simplexml_load_string($string_data);
$citta = (string)$xml->geoname->name;
echo $citta;
Demo Php
If you want to loop through mulitple items you could use:
foreach ($xml->geoname as $item) {
echo $item->name;
}
Update:
For the updated part you could use the same technique:
$xml = simplexml_load_file("https://maps.googleapis.com/maps/api/geocode/xml?latlng=41.51,15.16&key=AIzaSyClG_vc2nkQCzXqvDzW1maPrUWLyADI7xI");
foreach ($xml->result as $item) {
if ((string)$item->type === "administrative_area_level_3") {
echo $item->address_component->long_name;
}
}
Or by index [1]:
echo $xml->result[1]->address_component->long_name;

Well I am trying to make a simple php system.
Anywise I need to separate the text when I want to add it to the database.
So for example I want to add:
abc:123
I want that the : will be the separater, so it'll look like this:
abc
123
And then both will go to a different table.
Could someone help me with this? As I am not an experience PHP coder, yet I am willing to learn how to do this.
Kind regards
This is pretty basic stuff..
$data = explode(':','abc:123');
foreach($data as $word)
{
// some code here
}
Use Split:
<?php
$data = "abc:123";
list ($var1, $var2) = split (':', $data);
echo "Var1: $var1; Var2: $var2;<br />\n";
?>
You can achieve this using explode.
abc:123
Is a string. Let's define it as a variable:
$origin = "abc:123";
You can split the string, using : as the separator.
$separator = ":";
$exploded = explode($separator, $origin);
Now you have an array which you can use to access abc and 123 individually.
$pre = $exploded[0];
$post = $exploded[1];
You don't know how many splits there will be?
That's okay. Your array simply increases, meaning you can simply loop through the array and handle the values.
foreach ($exploded as $split)
{
// Do something with $split
}

I need to extract the value of the attributes of a html tag that is defined as a php variable:
[video src="http://localhost/video.mp4" poster="http://localhost/thumb.jpg" preload="none"][/video]
values of src and poster should be separated and cast to array
if your text is a php variable, you can use preg_match :
<?php
$text = '[video src="http://localhost/video.mp4" poster="http://localhost/thumb.jpg" preload="none"][/video]';
preg_match('/src=\"([^\"]+)\"/si', $text, $src);
preg_match('/poster=\"([^\"]+)\"/si', $text, $poster);
$array['src'] = $src[1];
$array['poster'] = $poster[1];
print_r($array);
?>
also you can use simplehtmldom
You can use an html parser for this. See this one: http://simplehtmldom.sourceforge.net/.
$html = str_get_html('<video src="http://localhost/video.mp4" poster="http://localhost/thumb.jpg" preload="none"></video>');
foreach($html->find('video') as $element)
{
$array['src'] = $element->src;
$array['poster'] = $element->poster;
}

Is it possible to get the text between <p></p> tags and set this in a variable?
<p>blabla</p> So i would like to get the text "blabla" and set this into a php variable so the variable would have the text value like this:.
<?$test = blabla;?>
Try:
$html = "<p>blabla</p>";
$dom = new DOMDocument;
$dom->loadXML($html);
$arr = $dom->getElementsByTagName('p');
foreach ($arr as $value) {
echo $value->nodeValue; // result => blabla
}
There are many methods which can be used based on your needs so take a look on documentation
DOMDocument
You can use this function, it is self explanatory:
function getTextBetweenTags($string, $tagname)
{
$pattern = "/<$tagname>(.*?)<\/$tagname>/";
preg_match($pattern, $string, $matches);
return $matches[1];
}
?>

I have an array of keys and a medium/long string.
I need to replace only max 2 keys that I found in this text with the same keys wrapped with a link.
Thanks.
ex.:
$aKeys = array();
$aKeys[] = "beautiful";
$aKeys[] = "text";
$aKeys[] = "awesome";
...
$aLink = array();
$aLink[] = "http://www.domain1.com";
$aLink[] = "http://www.domain2.com";
$myText = "This is my beautiful awesome text";
should became "This is my <a href='http://www.domain1.com'>beautiful</a> awesome <a href='http://www.domain2.com'>text</a>";
Don't really understood what you need but you can do something like:
$aText = explode(" ", $myText);
$iUsedDomain = 0;
foreach($aText as $sWord){
if(in_array($sWord, $aKeys) and $iUsedDomain < 2){
echo "<a href='".$aLink[$iUsedDomain++]."'>".$sWord."</a> ";
}
else{ echo $sWord." "; }
}
So, you could use a snippet like this. I recommend you to update this code by using clean classes instead of stuff like global - just used this to show you how you could solve this with less code.
// 2 is the number of allowed replacements
echo preg_replace_callback('!('.implode('|', $aKeys).')!', 'yourCallbackFunction', $myText, 2);
function yourCallbackFunction ($matches)
{
// Get the link array defined outside of this function (NOT recommended)
global $aLink;
// Buffer the url
$url = $aLink[0];
// Do this to reset the indexes of your aray
unset($aLink[0]);
$aLink = array_merge($aLink);
// Do the replace
return ''.$matches[1].'';
}
