I want to print a new line character in browser but '\n' in echo statement does nothing. Whats wrong in this code?
$n = 5;
for($i= 0; $i<=$n; $i++)
{
for($j=0; $j <= $n-$i-1; $j++)
echo " ";
for( ; $j <= $n; $j++)
echo '* ';
echo "\n";
}
It's actually working, if you see your html source you will find it, whereas HTML needs <br> instead of new line character. if you want to convert new line to <br> you can use php function nl2br.
echo nl2br($stingHasNewLineChar);
The "echo" command in PHP sends the output to the browser as raw html so even if in double quotes the browser will not parse it into two lines because a newline character in HTML means nothing. That's why you need to either use:
echo [output text]."<br>";
when using "echo", or instead use fwrite...
fwrite([output text]."\n");
This will output HTML newline in place of "\n".

In contradiction with the documentation, in the following cycle (I am creating a select) when the variable $retval reaches 2048 characters, it's set to null.
foreach ($cache_ecmcategories as $category) {
$retval.= '<option value="'.$category['rowid'].'"';
if (($isfilter ? $category['label'] : $category['rowid']) == $defaulttx)
$retval.= ' selected="selected"';
$retval.= '>'.$category['label'].'</option>'; <== This line generate the problem
}
Also, change the PHP version from 5.6.25 to 7.0.10, the problem remains the same
What is the cause of this strange behavior?
I can't reproduce your issue on my server with the following script:
<?php
$foo='';
for($i=0; $i < 1000; $i++) $foo .= "cur:$i ";
var_dump($foo);
Even an additional $foo .= NULL; doesn't trigger the bug for me.
Are you really sure that the bug happens on your posted code? Have you tried to add additional debug statements?

I am trying to create a unique id by concatenating 3 variables using forward slashes(/). my code is like so
$year . "/" . $acronym . "/" . $num;
I am expecting an output of
"18/MC/1"
but the output I get is
"18\/MC\/1"
What am I doing wrong. I have already tried using stripslashes() but it doesn't do anything to the output.
You could use join function
<?php
// ...
join([$year, $acronym, $num], '/');
For more info, see: Join function documentation
I found what was wrong,
The code below outputs the correct format 18/MC/1
return response()->json([$id]);
while my previous code was
return response()->json($id);
which gave me an output of
`"18/MC/1"
There is function in php to remove backward slash from string use following function.
echo stripslashes(string);
output: 18/MC/1

I've tried out some code where I use a for loop in PHP to add up numbers but it seems to not work, how can be?
$n = 3; //or anything else
for($i=0;$i<$n;$i++){
$n = $n+$n;
}
echo $n;
This is just a test code for something else, but I'd still like it to work, please help
You are increasing the loop ending condition $n inside the loop
this means it will never exit the loop.
this is an infinite loop, and wont ever print anything.
also your loop needs to be $i = 0; $i < $n; $i++

Please tell me how to do a find and replace in PHP.
I nee to find Entry="OK" and replace with OK in a xml file.
I tried str_replace but confused because of the = and " in it.
Even though I'm not sure of the environment you're working in, here's a php sample that I think does what you want:
<html>
<?php
$teststr = "Entry=\"OK\"";
print $teststr . "<br>";
$newanswer = str_replace($teststr, "Entry=OK", $teststr);
print $newanswer . "<br>";
?>
</html>
Try this way
str_replace('Entry="OK"','OK',$var);
You can use str_replace its working
$r = 'Entry="OK" tyyuu hhh';
echo str_replace($r,'Entry="OK"','OK');
if any error found then u use preg_replace with corresponding patteren

I was wondering if there was a way to bold certain words on a line. For example if I wanted every third word on a line bold, how would I do it. I am currently using addText but that requires the whole line to be bold or not bold. Any responses would be greatly appreciated.
You will need to use createTextRun() method. I have tried with Text.php file from Examples folder, and here is code relevant for your problem:
$textrun = $section->createTextRun();
$sentence='I am sentence, and every third word will be bold. This is bold.';
$word_arr=explode(' ', $sentence);
$styleFont = array('bold'=>true, 'size'=>16, 'name'=>'Calibri');
$styleFont2 = array('bold'=>false, 'size'=>16, 'name'=>'Calibri');
$c = 0;
for($i = 0; $i < count($word_arr); $i++)
{
$c++;
if($c % 3 == 0)
{
$textrun->addText($word_arr[$i].' ', $styleFont);
}
else
{
$textrun->addText($word_arr[$i].' ', $styleFont2);
}
}
You could tweak it to get what you want, but, basically, by using of mentioned method, it is possible to get different styles in same line.
