While trying to echo out a line, get an unexpected error for the following line:
echo "$arr[count($arr)]".')';
Cannot figure out what the fix might be. Want to print out the last item of the array.
Remove quotes and remember that array index starts from zero.
echo $arr[count($arr) - 1];
Or just:
echo end($arr);
try this:
echo '('.$arr[count($arr)].')';
Try this:
echo $arr[count($arr)];

I am trying to write a program using Call By Reference to calculate the area but I am getting a Parse Error :-
Parse error: syntax error, unexpected 'ar' (T_STRING) in C:\xampp\htdocs\workspace.php on line 7
Now I, cannot think why it is happening?
<?php
function perimeter(&$l,&$b,&$result)
{
$result=2*($l+$b);
}
funtction ar(&$le,&$br,&$result1)
{
$result1=$le*$br;
}
$result=1;
$length=$_GET['length'];
$breadth=$_GET['breadth'];
echo "<h1><center>Area And Perimeter Calculator Using Call By Reference</h1></center>";
$result = perimeter($length,$breadth,$result);
echo "<br />The Perimeter Of The Rectangle Is <strong>$result</strong>";
$result= ar($length,$breadth,$result);
echo "<br /><br />The Area Of The Rectangle Is = <strong>$result</strong>";
?>
You misspelled function:
funtction ar(&$le,&$br,&$result1)
{
$result1=$le*$br;
}
should be
function ar(&$le,&$br,&$result1)
{
$result1=$le*$br;
}

I am new to PHP and I am using PHP Version 5.4.17 in my mac. Below code with space gives me error. Once I remove the space in echo command, it gives me output but appended with Junk character. What am I doing wrong? Any help is appreciated
Code:
<?php
echo “Connection Success”;
?>
Error:
"Parse error: parse error, expecting ','' or';'' in /Library/WebServer/Documents/test org.php on line 2"
Code:
<?php
echo “ConnectionSuccess”;
?>
Output:
“ConnectionSuccessâ€
<?php
echo "ConnectionSuccess";
?>
You need to remove the bad quotes “ and ” and replace them with standard quotes: "

Following is my PHP code line:
$nic = "'".ADMIN_SITE_URL."'assets/img/watermark.png'";
$client->setWatermark($nic, 105, 148);
Here ADMIN_SITE_URL is a constant and I want to concatenate a string to this constant and wrap the whole sting into singlee quotes as this is going to be asigned as a parameter into a method named setWatermark(). But I'm not able to do it. Getting the error as:
PHP Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING in pdf_test_question_paper.php on line 83
Errors parsing pdf_test_question_paper.php
I'm not getting why this is happening. Can anyone help me in resolving this issue? Any help would be greatly appreciated.
Try That
$nic = "'".ADMIN_SITE_URL."assets/img/watermark.png'";

I have a String 7*10*6* I will separate the numbers, when I use explode function the out is:
Array
(
[0] => *
)
here is my code:
echo '<pre>';
print_r(explode('7*10*6','*'));
echo '</pre>';
what's the problem?
Oh boy, have you read the manual of explode?
the manual says:
explode(string $delimiter,string $string). You have done wrong. change your code to this:
print_r(explode('*','7*10*6'));
Try
print_r(explode('*','7*10*6'));
In explode function first argument is separator and second is string.

i have this simple typo issue here i guess.
How can i resolve it?
<?php the_content("<br /> <span class='custom-more'>Read More: " . get_the_title('', '', false) "</span>"); ?>
I need to make a read more button in WordPress and i need to wrap the read more inside a span class.
I get this error message:
Parse error: syntax error, unexpected T_CONSTANT_ENCAPSED_STRING in
How am i supposed to resolve this?
Thanks
You are missing the concatenation operator . between get_the_title function and </span>
<?
php the_content("<br /> <span class='custom-more'>Read More: ".get_the_title('', '', false)."</span>");
?>
You are missing the concatenate (.)
Correct code will be
php the_content("<br /> <span class='custom-more'>Read More: ".get_the_title('', '', false)."</span>");
