Word count like function Ver.1.0! This function can count your input text
and display only part of it (like a description) without cutting words in half

  function smart_text ($text_input_var[string] ,text_length[int])
  {
      $strip_content=stripslashes($content);
      $all_content=strlen("$strip_content"); 

      $standard_content=substr($strip_content ,$text_length);
      $compare=stristr($standard_content ," ");
      $minus_content=strlen("$compare"); 

      $result_content=$all_content-$minus_content;
      $display_content=substr($strip_content ,0, $result_content); 

      $striped_content=stripslashes($display_content);
      echo nl2br($striped_content);
  } 

For example i insert a 300 words test but only want about 3 rows of it to be displayed
without cutting words in half. 

function smart_text($text,200) 

Displayed result will be the first 200 letters of the text plus the letters till the first space
char.

Trim Function

Left - ltrim() function
<?php 

$text = "\t\tThese are a few words   ...  ";
$trimmed = ltrim($text);
// $trimmed = "These are a few words   ...  "
$trimmed = ltrim($text," \t.");
// $trimmed = "These are a few words   ...  "
$clean = ltrim($binary,"x00..x1F");
// trim the ASCII control characters at the beginning of $binary
// (from 0 to 31 inclusive) 

?> 

Right - rtrim() function
<?php 

$text = "\t\tThese are a few words   ...  ";
$trimmed = rtrim($text);
// $trimmed = "\t\tThese are a few words   ..."
$trimmed = rtrim($text," \t.");
// $trimmed = "\t\tThese are a few words  "
$clean = rtrim($binary,"x00..x1F");
// trim the ASCII control characters at the end of $binary
// (from 0 to 31 inclusive) 

?>

This function allows you to take any string and split it into fairly even pieces

<? 

function breakString($str="", $pieces="") { 

// Find out how big the string is
$len = strlen($str); 

// String size can't be less than pieces
if ($len < $pieces) {
    $ary[0] = "String Size is less than Number of Pieces";
    return $ary;
} 

// Find out how big each piece should be
$lim = $len / $pieces;
$start = 0;
$i = 0;
$l = 0; 

// Split string into individual characters
for ($k = 0; $k < $len; $k++) {
     $x = $k + 1;
     $g[$k] = substr($str,$k,1);
} 

// Start Making Pieces
while ($i < $pieces) { 

// Glue Pieces Back Togeather
   for ($j = $start; $j < $lim; $j++) {
       $tmp = $tmp . $g[$l];
       $l++;
   } 

// Back up one character in the array
   $x = $l - 1; 

// If Last Charecter is NOT a space, AND this is NOT the last piece,
// Go until the next  space is found
   while (($g[$x] != " ") AND ($i != $pieces -1)) {
     $tmp = $tmp . $g[$l];
     $g[$x] = $g[$l];
     $l++;
   } 

// Move this String into array piece
   $ary[$i] = $tmp;
// Reset String
   $tmp = "";
   $i++;
} 

// Output String
   return $ary; 

} 

$text = "this is a little test with php3, MYSQL and Apache on my webserver. It works fine but i have to learn a lot about php3!";
echo("<b>$text</b><br><br>"); 

$now = breakString($text, 3); 

$sze = sizeof($now); 

for ($ii = 0; $ii < $sze; $ii++) {
     echo("$now[$ii]<br>");
} 

?>

Sub String Replace

<?php
$var = 'ABCDEFGH:/MNRPQR/';
echo "Original: $var<hr>\n"; 

/* These two examples replace all of $var with 'bob'. */
echo substr_replace($var, 'bob', 0) . "<br>\n";
echo substr_replace($var, 'bob', 0, strlen($var)) . "<br>\n"; 

/* Insert 'bob' right at the beginning of $var. */
echo substr_replace($var, 'bob', 0, 0) . "<br>\n"; 

/* These next two replace 'MNRPQR' in $var with 'bob'. */
echo substr_replace($var, 'bob', 10, -1) . "<br>\n";
echo substr_replace($var, 'bob', -7, -1) . "<br>\n"; 

/* Delete 'MNRPQR' from $var. */
echo substr_replace($var, '', 10, -1) . "<br>\n";
?>

Sorting Strings

<?php

echo "Standard string comparison\n";
usort($arr1,"strcmp");
print_r($arr1);
echo "\nNatural order string comparison\n";
usort($arr2,"strnatcmp");
print_r($arr2);
?> 

/* Output
