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.

If I have a paragraph:
echo "^b(This sentence becomes bold), and ^i(this becomes italic).\nThen this becomes ^up(uppercase).";
how to replace ^b, ^i, ^up, \n into a HTML tags ?
This sentence becomes bold, and this becomes italic.
Then this becomes UPPERCASE.
Thankyou.
You could try to use preg_replace() with patterns to do this:
<?php
// your example text
$text = "^b(This sentence becomes bold), and ^i(this becomes italic).\nThen this becomes ^up(uppercase).";
// array of patterns
$patterns = [];
$patterns[0] = "/\^b\((.*?)\)/";
$patterns[1] = "/\^i\((.*?)\)/";
$patterns[2] = "/\^up\((.*?)\)/";
// array of replacements
$replacements = [];
$replacements[0] = '<b>${1}</b>';
$replacements[1] = '<i>${1}</i>';
$replacements[2] = '<span style="text-transform:uppercase;">${1}</span>'; // or use something better here
// process the text
$formattedText = preg_replace($patterns, $replacements, $text);
// see the result
echo $formattedText;
?>
It would be much better if you write this logic in a helper function so you could use it easier on different places later.

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 want to cut text before "DETAIL" .
<?PHP
$text="Name:myproduct Price:99 DETAIL :abcdedsfsdff 21348dfsdf ds "
//i want result Name:myproduct Price:99
?>
You are going to need to use substr which is used to get the substring of a string along with strpos which gives the position of the given occurance:
echo substr($text, 0, strpos($text, 'DETAIL'));
Visit php.net
You can split the text in array and get the first element of array:
$text="Name:myproduct Price:99 DETAIL :abcdedsfsdff 21348dfsdf ds ";
$abc = explode('DETAIL',$text);
echo $abc[0];
$text = "Name:myproduct Price:99 DETAIL :abcdedsfsdff 21348dfsdf ds";
$clean = substr($text, 0, stripos($text, "detail"));
echo $clean;
This will output
Name:myproduct Price:99
$text = "Name:myproduct Price:99 DETAIL :abcdedsfsdff 21348dfsdf ds";
$clean = substr($text, stripos($text, "detail"), strlen($text) - 1);
echo $clean;
This will output
DETAIL :abcdedsfsdff 21348dfsdf ds

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

How to separate the sentence by "comma" and at last using "and " in PHP Like
"Bruce_Campbell is an actor and director and creator and producer and musician."?
now i want to to show the the sentence like this...
""Bruce_Campbell is an actor , director ,creator , producer and musician.""
You don't want to replace the last and in the string.
$str = "Bruce_Campbell is an actor and director and creator and producer and musician.\n";
$except_last_and = substr_count($str, 'and') - 1;
$resStr = preg_replace("/and/", ' , ', $str, $except_last_and);
echo $resStr;
But Gautam3164 is correct you should Google first.
And the PHP manual is a great resource.
http://ca1.php.net/preg_replace
http://www.php.net/manual/en/function.substr-count.php
One line solution:
$str = "Bruce_Campbell is an actor and director and creator and producer and musician.";
print str_replace(" and ",", ", substr($str, 0, strripos($str, 'and'))).substr($str, strripos($str, 'and'), strlen($str));
Bruce_Campbell is an actor, director, creator, producer and musician.
