Functions
html_numeric_entity_decode()
Convert numeric HTML entities to their corresponding characters
html_numeric_entity_decode(string $str) : string
Act like html_entity_decode() builtin but converts also control characters.
Parameters
- $str : string
Tags
Return values
stringmb_ucfirst()
A unicode aware replacement for ucfirst()
mb_ucfirst(string $str) : string
Parameters
- $str : string
Tags
Return values
stringmb_str_word_count()
count UTF-8 words in a string
mb_str_word_count(string $str[, string $format = 0 ][, string $charlist = "" ]) : int|array<string|int, string>
This simple utf-8 word count function (it only counts) is a bit faster then the one with preg_match_all about 10x slower then the built-in str_word_count
If you need the hyphen or other code points as word-characters just put them into the [brackets] like [^\p{L}\p{N}'-]
Parameters
- $str : string
- $format : string = 0
- $charlist : string = ""

mb_explode(string $delimiter, string $string[, int $limit = PHP_INT_MAX ]) : string
Parameters
- $delimiter : string
- $string : string
- $limit : int = PHP_INT_MAX
-
Default is PHP_INT_MAX.
Return values
stringmb_str_pad()
Simulate str_pad() for multibytes strings
mb_str_pad(string $str, int $pad_len[, string $pad_str = ' ' ][, string $dir = STR_PAD_RIGHT ][, string $encoding = NULL ]) : string
Parameters
- $str : string
- $pad_len : int
- $pad_str : string = ' '
-
Default is ' '.
- $dir : string = STR_PAD_RIGHT

Default is NULL.
- $encoding : string = NULL
-
Default is NULL.
Return values
stringmb_trim()
Code by Ben XO at https://www.php.net/manual/en/ref.mbstring.php
mb_trim(string $string[, string $charlist = '\\s' ][, bool $ltrim = TRUE ][, bool $rtrim = TRUE ]) : string
Trim characters from either (or both) ends of a string in a way that is multibyte-friendly.
Mostly, this behaves exactly like trim() would: for example supplying 'abc' as the charlist will trim all 'a', 'b' and 'c' chars from the string, with, of course, the added bonus that you can put unicode characters in the charlist.
We are using a PCRE character-class to do the trimming in a unicode-aware way, so we must escape ^, , - and ] which have special meanings here. As you would expect, a single \ in the charlist is interpretted as "trim backslashes" (and duly escaped into a double-\ ). Under most circumstances you can ignore this detail.
As a bonus, however, we also allow PCRE special character-classes (such as '\s') because they can be extremely useful when dealing with UCS. '\pZ', for example, matches every 'separator' character defined in Unicode, including non-breaking and zero-width spaces.
It doesn't make sense to have two or more of the same character in a character class, therefore we interpret a double \ in the character list to mean a single \ in the regex, allowing you to safely mix normal characters with PCRE special classes.
Be careful when using this bonus feature, as PHP also interprets backslashes as escape characters before they are even seen by the regex. Therefore, to specify '\s' in the regex (which will be converted to the special character class '\s' for trimming), you will usually have to put 4 backslashes in the PHP code - as you can see from the default value of $charlist.
Parameters
- $string : string
-
The string to trim
- $charlist : string = '\\s'
-
charlist list of characters to remove from the ends
- $ltrim : bool = TRUE
-
trim the left? (Default is TRUE)
- $rtrim : bool = TRUE
-
trim the right? (Default is TRUE)
