PHP has str_split () function, which is used to print every character of a string. No need to use any loop.
You can use the PHP strpos() function to check whether a string contains a specific word or not. The strpos() function returns the position of the first occurrence of a substring in a string. If the substring is not found it returns false .
Step 1: convert the string to an array using the str_split function
$array = str_split($your_string);
Step 2: loop through the newly created array
foreach ($array as $char) {
echo $char;
}
You can check the PHP docs for more information: str_split
Iterate string:
for ($i = 0; $i < strlen($str); $i++){
echo $str[$i];
}
If your strings are in Unicode you should use preg_split with /u modifier
From comments in php documentation:
function mb_str_split( $string ) {
# Split at all position not after the start: ^
# and not before the end: $
return preg_split('/(?<!^)(?!$)/u', $string );
}
You can also just access $s1 like an array, if you only need to access it:
$s1 = "hello world";
echo $s1[0]; // -> h
