stristr in php code example

Example 1: strpos in php

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

// Note our use of ===.  Simply == would not work as expected
// because the position of 'a' was the 0th (first) character.
if ($pos === false) {
    echo "The string '$findme' was not found in the string '$mystring'";
} else {
    echo "The string '$findme' was found in the string '$mystring'";
    echo " and exists at position $pos";
}
?>

Example 2: stristr php

<?php
  $string = 'Hello World!';
  if(stristr($string, 'terre') === FALSE) {
   echo '"terre" non trouvé dans la chaîne de caractères';
  }
// affiche : "terre" non trouvé dans la chaîne de caractères
?>
