It is fairly simple to check the length of a string in PHP. All you need to do is use the function strlen(). Below is an example of how it is used.
<?php
$my_text = "Hello";
echo strlen($my_text); // outputs 5
?>
You can do this: <?php if ( $word === strrev( $word ) ) { echo "The word is a palindrome"; } else { echo "The word is not a palindrome"; }
According to PHP official manual It is used to converts a string to an array.If the optional split_length parameter is specified, the returned array will be broken down into chunks with each being split_length in length, otherwise each chunk will be one character in length. FALSE is returned if split_length is less than 1.If the split_length length exceeds the length of string, the entire string is returned as the first (and only) array element. Syntax: array str_split ( string string [, int split_length] );Example :< ?php$strW3 = "Hello w3answers";$arrW3 = str_split($strW3 );$arrW3 = str_split($strW3 , 3);print_r($arrW3);print_r($arrW3);?>
md5() is one-way encryption method. Example: $test_string="php"; $md_encoded_string=md5($test_string); But, you can't decode the string back to php.So, if you need to check the entered string is php or not $user_entered_string=md5($_POST['user_input']); if($md_encoded_string == $user_entered_string) { echo "input matched"; }
You could use a function like this:function isPalindrome($string) {$string = strtolower($string);return (strrev($string) == $string) ? true : false;}and then to check a palindrome call an if statement like so:if(isPalindrome($test)) {echo $test.' is a palindrome';}else {echo $test.' is not a palindrome';}
"Text move" isn't very clear. If you want to assign strings to different variables, use the assignment operator: <?php $old_var = 'blah'; $new_var = $old_var; echo $new_var; // Displays "blah" ?> If you want to work with a certain part of a string, use substr(): <?php $part_of_string = substr($string, $start, $length); // $start should be an integer, indicating which character to start obtaining the string at // $length should be an integer, indicating how many characters you want to obtain. echo = substr('somesimplestring', 5, 6); // Displays "simple" ?>
$string ="Guess my length"; $length = strlen($string); now the $length will have the length of the string.
You can do this: <?php if ( $word === strrev( $word ) ) { echo "The word is a palindrome"; } else { echo "The word is not a palindrome"; }

Varchar in SQL means string in PHP.
<?php trim(ereg_replace( ' +', ' ', $extraWhiteSpace)); ?>
$str = "Hello"; $nameArr=str_split($str); print_r($nameArr); echo "length: ".count($nameArr);
string length is a function use to check the lenght of a string i.e number of alphabets in a word or sentence.
If you will see this example as below, this may help. <?php $string = mysql_real_escape_string($string); $sql = "insert into stringtable(mystring) values('$string')"; ?>
