//echo $str;

$result = stristr($str, 'event');
$a=str_replace(" ","<br>","$result");

$b=stristr($str, 'event');

finding if string exist strripos()

Example #1 A simple strripos() example

<?php
$haystack = 'ababcd';
$needle = 'aB';

$pos = strripos($haystack, $needle);

if ($pos === false) {
echo "Sorry, we did not find ($needle) in ($haystack)";
} else {
echo "Congratulations!\n";
echo "We found the last ($needle) in ($haystack) at position ($pos)";
}
?>

The above example will output:

Congratulations!
We found the last (aB) in (ababcd) at position (2

php searching string using stristr() & strpbrk()

<?php
$email = 'name@example.com';

$domain = stristr($email, '@');

echo $domain."<br>"; // prints @example.com

$user = stristr($email, '@', true); // As of PHP 5.3.0

echo $user;

echo "<br>";

echo strpbrk($email,'a');

?>

@example.com
name
ame@example.com

finding if string exist on string strpos()

<?php
$mystring = 'abc';
$findme = 'a';
$pos = strpos($mystring, $findme);

// The !== operator can also be used. Using != would not work as expected
// because the position of 'a' is 0. The statement (0 != false) uates
// to false.
if ($pos !== false) {
echo "The string '$findme' was found in the string '$mystring'";
echo " and exists at position $pos";
} else {
echo "The string '$findme' was not found in the string '$mystring'";
}

php explode and list() function

<?php

$data = "foo:*:1023:1000::/home/foo:/bin/sh";
list($user, $pass, $uid, $gid, $gecos, $home, $shell) = explode(":", $data);
echo $user; // foo
echo $pass; // *

?>

<?php

$data = "foo:*:1023:1000::/home/foo:/bin/sh";
$r=list($user, $pass, $uid, $gid, $gecos, $home, $shell) = explode(":", $data);

foreach($r as $value ){

echo $value."<br>";
}

?>

$datetime1 = strtotime($datetime ); //convert date to unixtime
$datetime2 = time(); //actual date on unixtime
$interval = abs($datetime2 - $datetime1);
$minutes = round($interval / 60);
return $minutes;
