PHP Basic Algorithm: Exercise-85 with Solution
Write a PHP program to create a new string from a given string. If the first or first two characters is 'a', return the string without those 'a' characters otherwise return the original given string.
Sample Solution:
PHP Code :
<?php
// Define a function named 'test' that manipulates a string based on the presence of the character 'a'
function test($s1)
{
// Check if the length of $s1 is 1 and if the character is 'a'
if (strlen($s1) == 1 && substr($s1, 0, 1) == "a")
{
// Remove the character 'a' from $s1
$s1 = substr($s1, 1);
}
// Check if the length of $s1 is greater than 1
if (strlen($s1) > 1)
{
// Check if the second character is 'a'
if (substr($s1, 1, 1) == "a")
{
// Remove the second character from $s1
$s1 = substr($s1, 0, 1) . substr($s1, 2);
}
// Check if the first character is 'a'
if (substr($s1, 0, 1) == "a")
{
// Remove the first character from $s1
$s1 = substr($s1, 1);
}
}
// Return the modified or original string
return $s1;
}
// Test the 'test' function with different strings, then display the results
echo test("abcab") . "\n";
echo test("Python") . "\n";
echo test("aacda") . "\n";
echo test("jython") . "\n";
?>
Sample Output:
bcab Python cda jython
