PHP - Php Concatenate
I know that usually when we concatenante in PHP we use the period . to concatenate but I have been watching a few videos and they seems to use a comma , instead of .
I didn't know about the comma before and if I didn't hear it wrong the video says both would work just depend on the way you work.
So I tried using comma for testing such as
echo '<pre>' , print_r($var) , '</pre>';which works fine but when I use it in a function for fun such as
function dd($var){
return '<pre>' , print_r($var) , '</pre>';
}
this gives me errors about the comma but if I use period as concatenate the page would not return as html tag <pre>
I know that I can just use var_dump and I tried searching things like difference between , and . in php or something similiar I couldn't find a page to explain the major difference.
Can someone give me a hand? Sorry if this question is too stupid though.
Similar TutorialsWhy won't '../stuff.com' concatenate? Code: [Select] <?php echo '<img src="', '../stuff.com'.getUserAvatar($post['username']), "\" class=\"avatar small\" title=\"${displayName}\" alt=\"${displayName}\" />"; ?> I have the variables $cap and $url If the $cap contains any of the strings ".jpg,.JPG,.gif,GIF" I have to concatenate $url.$cap I need to put this inside of a p tag so I can change some properties but everything I've tried doesn't work and just shows nothing.
I've tried this:
printf('<p style="text-align: left; width: 500px;">', htmlspecialchars($fetch['shout'], ENT_QUOTES, 'UTF-8'), '</p>');
This is what I need to be wrapped in p tags:
htmlspecialchars($fetch['shout'], ENT_QUOTES, 'UTF-8');EDIT: I've noticed the code below works but when I style it inside of the tag the text won't show, should I include a CSS file on the PHP file? echo "<p>".htmlspecialchars($fetch['shout'])."</p>\n";EDIT: I just needed to create the CSS for the p tags in the index and it worked perfectly fine. Sorry for the pointless thread. Edited by Alanay, 18 December 2014 - 09:14 AM. First project in php and mysql, I've searched but can't find the answer to stringing together two numbers and a "-" without php giving me the results as it thinks I'm creating an equation. I need the string as text. Example, I need the following as a text string, id_have (INT) and id_have (INT) joined together as id_have-id_want, or, as they will be numbers, 23-45. When I use this; $havewant = $id_have . "-" . $id_have; The result will be $id_have (23) minus $id_want (45), I get -22, not what I'm looking for!!! I need the text string of "23-45" to store in a table. Thanks! Hello I have an array where i want the join values (not sum) where the date are the same This my array(var_export)

So, for example i have repeated the date 2020-10-20, one with "tempos =1" and another with "tempos=3" I'm looking to have only one date with concatened tempos field Example
array (
'dataAula' => '2020-10-20',
'tempos' => 1+3,
'tempos2' => 'Terça',
'total' => 33,
),
So what i have now is this code but not getting what i need
foreach ($finalCronograma as $sub) {
$row = current($sub);
if (isset($result[$row[0]['dataAula']])) {
$result[$row[0]['dataAula']]['tempos'] .= '+' . $row[0]['tempos'];
} else {
$result[$row[0]['dataAula']] = $sub;
}
}
any help? This topic has been moved to MySQL Help. http://www.phpfreaks.com/forums/index.php?topic=313826.0 I have the following mysql query: Code: [Select] $lead_query=$this->db->query(" SELECT `first_name`, `last_name` , `state` FROM leads WHERE `lead_id`='$lead_id' "); $this->view->lead_query=$lead_query->fetchALL(); Now when I retrieve the above details I need to return the first_name last_name together(separated as space) and the name of the key as client_name in the array. I need it that way because when i return a json_encode($lead_query), I want to return the first_name.last_name as client_name. I'm trying to get a php script working to download the latest CNN news podcast each hour. CNN names the file based on the year, month, day, and time. Here's what I'm trying: Code: [Select] <?php $year = date('Y'); $month = date('m'); $day = date('d'); $now = date('Y-m-d-h'); $hour = date('gA'); $hourplus1 = ($hour + 1); $hourminus1 = ($hour - 1); $ampm = date('A'); $url = "http://podcasts.cnn.net/cnn/services/podcasting/newscast/" . "audio/" . "$year" . "/" . "$month" . "/" . "$day" . "/CNN-News-" . "$month" . "-" . "$day" . "-" . "$year" . "-" . "$hourplus1" . "$ampm" .

Hello, I am trying insert the values of csv file into a table. I want to concatenate the values of some columns of csv into one String column of table by delimiting them my commas. $im="INSERT into TB1 (col1, col2 ) values ('$a[2]','$a[3]')"; $b = ""; $b=".'$a[6]'."||".'$a[7]'."||".'$a[8]'."||".'$a[9]'."; $im1=$im+"UPDATE TB1 set latlng=.'$aline'."; mysql_query($im1) OR die(mysql_error()); I need to enter the value of $a[6] till $a[9] into a string column with delimiters and insert into the column col3 of TB1 with value as $a[4]. I am stuck up here could anyone help me with this issue. Although I am deciding on the best route to go on this, I was hoping for any feedback or ideas on the best and simplest approach to the below problem: Here is my table structu old_code_1 old_code_2 new_code_1 new_code_2 prod_code_1 prod_code_2 Each of the following fields has 5 digits e.g. 00045, 12654, etc. What I need to achieve is this: Concatenate each set (of the 3 sets above) data into one variable e.g. old_code_1 + old_code_2 = 0004512654. So old_code_1 & old_code_2 would become a combined data and the same for the othe 2 sets. Then. Once concatenated, I need to compa prod_code_1+prod_code_2 with old_code_1+old_code_2 and replace prod_code_1+prod_code_2 with new_code_1+new_code_2 where matches are found. The new_code_1 & 2 are in the same row as the old_code 1 & 2. So the data is in alignment that way for comparison. Thanks for any insight or suggestions on how to make this happen in the simplest form possible. |
