stripossearches for the first occurrence of a substring in a string, ignoring case.strripossearches for the last occurrence of a substring in a string, ignoring case.
CODE:
<?php
$string = "This is a test by Tom. He is a good boy. This is another test";
echo "Main sentence is:<br>";
echo $string;
echo '<br>Search the word "test" using strpos() <br>';
echo strpos($string, "test");
echo '<br>Search the word "Test" using strpos() <br>';
echo strpos($string, "Test");
if(strpos($string, "Test")){
echo "Word Found";
}else{
echo "Word not found--as strpos() is case sensitive";
}
echo '<br>Search the word "Test" using stripos()-- case sensitive <br>';
echo stripos($string, "Test");
echo '<br>Search the word "This" using stripos()-- case sensitive <br>';
echo stripos($string, "This");
echo "<br>";
if(stripos($string, "This") !== false ){
echo " Word is found";
}else{
echo "Word not found";
}
echo '<br>Search the word "This" using strripos()-- case sensitive. <br>';
echo strripos($string, "This");
echo "<br>";
echo "Another Test<br>";
$text = "This is a test. This is only a test.";
echo $text;
echo "<br>";
$substring = "test";
$firstPos = stripos($text, $substring);
$lastPos = strripos($text, $substring);
echo "First occurrence of test: " . $firstPos . "\n";
echo "Last occurrence of test: " . $lastPos . "\n";

Split String or String tokenization
CODE:
<?php
$sentence ="Hello World, My name is Jimmy";
echo "split using explode<br>";
$split1= explode(" ",$sentence);
print_r($split1);
echo "<br>Join Splitted Sentence<br>";
$join1=join(" ",$split1);
echo $join1;
echo "<br>Join splitted sentence using implode<br>";
$join2 = implode(" ",$split1);
echo $join2;
echo "<br>Split string using multiple delimeter<br>";
$split2 = strtok($sentence," ,");
while ($split2 !== false){
echo $split2."<br>";
$split2=strtok(" ,");
}
print_r($split2);
echo "<br>Split string using regular expression <br>";
$split3= preg_split("/ |,/",$sentence);
print_r($split3);
echo "<br>Split \"Hello World\" in characters<br>";
echo <<<MyText
Split "Hello WOrld" in Characters <br>
MyText;
$split4 = str_split("Hello World");
print_r($split4);

Reverse String in various ways
CODE:
<?php
$sentence = "My name is Jon";
echo "<br>Main sentence is:<br>";
echo $sentence;
$rev1= strrev($sentence);
echo "<br>First Reversal:<br>";
echo $rev1;
echo "<br>2nd Reversal system: <br>";
$rev2= "";
for($i=1;$i<=strlen($sentence);$i++){
$rev2.=$sentence[$i * -1] ;
}
echo $rev2 ;
$rev3="";
echo "<br>3nd Reversal system: <br>";
for($i=strlen($sentence);$i>=0;$i--){
$rev3.= $sentence[$i];
}
echo $rev3;
