strtolower

Returns string with all ASCII alphabetic characters converted to lowercase.

Bytes in the range «A» (0x41) to «Z» (0x5a) will be converted to the corresponding lowercase letter by adding 32 to each byte value.

This can be used to convert ASCII characters within strings encoded with UTF-8, since multibyte UTF-8 characters will be ignored. To convert multibyte non-ASCII characters, use mb_strtolower() .

Parameters

Return Values

Returns the lowercased string.

Changelog

Version	Description
8.2.0	Case conversion no longer depends on the locale set with setlocale() . Only ASCII characters will be converted.

Examples

Example #1 strtolower() example

$str = «Mary Had A Little Lamb and She LOVED It So» ;
$str = strtolower ( $str );
echo $str ; // Prints mary had a little lamb and she loved it so
?>

strtolower(); doesn’t work for polish chars

the best solution — use mb_strtolower()

for cyrillic and UTF 8 use mb_convert_case

$string = «Австралия» ;
$string = mb_convert_case ( $string , MB_CASE_LOWER , «UTF-8» );
echo $string ;

the function arraytolower will create duplicate entries since keys are case sensitive.

$array = array( ‘test1’ => ‘asgAFasDAAd’ , ‘TEST2’ => ‘ASddhshsDGb’ , ‘TeSt3 ‘ => ‘asdasda@asdadadASDASDgh’ );

$array = arraytolower ( $array );
?>
/*
Array
(
[test1] => asgafasdaad
[TEST2] => ASddhshsDGb
[TeSt3] => asdasda@asdadadASDASDgh
[test2] => asddhshsdgb
[test3] => asdasda@asdadadasdasdgh
)
*/

function arraytolower ( $array , $include_leys = false )

if( $include_leys ) <
foreach( $array as $key => $value ) <
if( is_array ( $value ))
$array2 [ strtolower ( $key )] = arraytolower ( $value , $include_leys );
else
$array2 [ strtolower ( $key )] = strtolower ( $value );
>
$array = $array2 ;
>
else <
foreach( $array as $key => $value ) <
if( is_array ( $value ))
$array [ $key ] = arraytolower ( $value , $include_leys );
else
$array [ $key ] = strtolower ( $value );
>
>

return $array ;
>
?>

which when used like this

$array = $array = array( ‘test1’ => ‘asgAFasDAAd’ , ‘TEST2’ => ‘ASddhshsDGb’ , ‘TeSt3 ‘ => ‘asdasda@asdadadASDASDgh’ );

$array1 = arraytolower ( $array );
$array2 = arraytolower ( $array , true );

print_r ( $array1 );
print_r ( $array2 );
?>

will give output of

Array
(
[test1] => asgafasdaad
[TEST2] => asddhshsdgb
[TeSt3] => asdasda@asdadadasdasdgh
)
Array
(
[test1] => asgafasdaad
[test2] => asddhshsdgb
[test3] => asdasda@asdadadasdasdgh
)

When you’re not sure, how the current locale is set, you might find the following function useful. It’s strtolower for utf8-formatted text:

function strtolower_utf8 ( $inputString ) $outputString = utf8_decode ( $inputString );
$outputString = strtolower ( $outputString );
$outputString = utf8_encode ( $outputString );
return $outputString ;
>
?>

It’s not suitable for every occasion, but it surely gets in handy. I use it for lowering German ‘Umlauts’ like ä and ö.

function strtolower_slovenian ( $string )
$low =array( «Č» => «č» , «Ž» => «ž» , «Š» => «š» );
return strtolower ( strtr ( $string , $low ));
>

how to capitalize all words in php

In order to make ucwords() worked properly in Turkish words that contain speacial characters, we can use the following command in our php codes: setlocale(LC_ALL, ‘tr_TR’); This will set locale to Turkish.

In this article, we go over how to capitalize each (and every) word in a string using the ucwords() function. The ucwords() function capitalizes the first letter of all the words in a string. So, if we have the string «wild at heart», after passing it through the ucwords() function, the string would then change to «Wild at Heart».

strtoupper() function– For making a PHP string uppercase (all letters in the string) strtolower() function – that converts a specified string to lowercase letters. ucwords() – camel cased i.e. capitalizes the first letter of each word in a string. For making the first letter of a string capital, use the ucfirst() function of PHP.

Notice that the last word «hELP» did not have the capitalization changed on the letters that weren’t first, they remained capitalized. If you want to ensure that only the first letter is capitalized in each word of your title, first use the strtolower function and then the ucwords function.

Returns a string with the first character of str capitalized, if that character is alphabetic. Note that ‘alphabetic’ is determined by the current locale. For instance, in the default «C» locale characters such as umlaut-a (ä) will not be converted.

With PHP you can perform a number of capitalization or case-changing operations on strings. You can capitalize all the letters in a string, the first letters of words only, or even the first letter of a string only. You can also convert parts of a string to lowercase if that is what you need to do.
