How do i remove underscore from this echo?
if($validation->fails())
{
echo '<div class="error_message">', ($validation->errors()->first('first_name')), '</div>';
}
Thank you.
what madness is this?
if($validation->fails()) {
echo '<div class="error_message">' . str_replace("_"," ",($validation->errors()->first('first_name'))) . '</div>';
}
To replace a string char you have to use str_replace function.
Here is an example:
$var = "Hello_World";
$var = str_replace("_"," ",$var);
echo $var;
Output:
Hello World

all I want to know what's the syntax error in this code.
echo "<p id='hide_text_$heading->id' >"preg_replace($rx, "<b>$0</b>", $heading->shortHeadline)"</p>";
Use . to concatenate strings. Change your code to
echo "<p id='hide_text_$heading->id' >" . preg_replace($rx, "<b>$0</b>", $heading->shortHeadline) . "</p>";
to concatenate the three parts or separate each statement:
echo "<p id='hide_text_$heading->id' >";
echo preg_replace($rx, "<b>$0</b>", $heading->shortHeadline);
echo "</p>";

you forget concatination sympol => .
Also there is syntax error in $0 if you mean by that variable name.
variable name could not start with numbers
only _ and string characters as i remember.
echo "<p id='hide_text_".$heading->id."' >" . preg_replace($rx, "<b>.$0.</b>", $heading->shortHeadline) . "</p>";

If I use the below code, I get the literal string <b> DATE: <?php echo $date; ?> </b> appended to content:
$content .= '<b> DATE: <?php echo $date; ?> </b>';
$pdf->writeHTML($content);
How can I instead get the value of $date there?
You are trying to put php code inside a string which will not be evaluated again. Try this:
$content .= '<b> DATE: ' . $date . '</b>';
$pdf->writeHTML($content);

my str is :
999999999
Now, how can i add "-" in this str ?
my example with "-" :
99-9-9-99999
Try this code -
<?php
$str = "999999999";
$output = substr($str,1,2)."-".substr($str,2,1)."-".substr($str,3,1)."-".substr($str,4,5);
echo "$output";
?>
output - 99-9-9-99999
You can use preg_replace() to format the number.
<?php
$num = "999999999";
$new_num = preg_replace("/([0-9]{2})([0-9]{1})([0-9]{1})([0-9]{5})/", "$1-$2-$3-$4", $num);
echo $new_num;
?>
Output:
99-9-9-99999

I am designing a small application which shoots out status-like tweets from users at the five latest ones. To keep it a small application, I need for it to accept only so many characters on a line and the drop a line just below it. So for example:
Noah: The best thing about Stackoverflow
is that it is full of amazing programmers.
Something along the lines of something like that above. Can you help me with the code below :
echo "<div style='position:relative;top:-20px;padding-top:10px;padding-left:30px;padding-right:30px;'>";
echo "<p> $first_name: $body. </p>";
if (strlen($body <= 100)) {
echo "\n";
}
echo "</div>";
}
wordwrap will do that for you
string wordwrap ( string $str [, int $width = 75 [, string $break = "\n" [, bool $cut = false ]]] )
Example:
$text = "A very long woooooooooooord.";
$newtext = wordwrap($text, 8, "\n", true);
echo "$newtext\n";
A very
long
wooooooo
ooooord.

For exemple, it's possible to replace
{'a1b2,left'}
with
<img src="a1b2" class="left"/>
in Php?
Yes...
$str = preg_replace('/\{\'(.*?),(.*?)\'\}/', '<img src="$1" class="$2"/>', $str);
yes you can.
//strip unwanted characters.
$string = preg_replace("/[{'}]/", "", $string);
//convert string to array
$string = explode(',', $string);
<img src="<?php echo $string[0]; ?>" class="<?php echo $string[1]; ?>"/>
