Parameters: *s String to parse

Returns: The new string, with slashes

Create an array from a string separated by some special char.Divides the src string in pieces, each delimited by token and storing the total of pieces in total

Parameters: src String to parse

token Character delimiter to search.

total An integer variable passed as reference, which stores the total of itens of the array

Returns: The array, where each item is one separeted by token

char **pieces; char *name = 'This,is,a,string,of,test'; int total, i; pieces = explode(name, ',', &total); for (i = 0; i < total; i++) printf('Piece %d: %sn', i, *(pieces+i));

Strip left white spaces from a string.Parameters: str String to parse

Returns: The new string, without left spaces

char *s = ' String with spaces '; printf('_%s_n', s); s = ltrim(s); printf('_%s_n', s);

Makes a string.Works like printf(), with the difference that it returns a string that is the concatenation of the values passed as parameter.

Parameters: *s Inicial String and optionally formatation parameters ( just s is allowed )

Returns: The new String

char *sql = make_string('INSERT INTO myTable VALUES ('%s', '%s', '%s')', varValue1, varValue2, varValue3);

Todo String limits/error checking

Reads an entire line.Reads a line from the file specified by the file pointer passed as parameter. This function is intead to replace the non-portable GNU getline() function.

Decode a base64 encoded string.Parameters: *str Encoded String to decode

Returns: The decoded string

See also: str_base64_encode

Encodes a given tring to its base64 form.Parameters: *str String to convert

Returns: Base64 encoded String

See also: str_base64_decode

Replace characteres in a string, but not more than 'n'.Replace all occourences of *delim on *src with characteres pointed by *with, stopping after 'n' char.

Parameters: *src String to parse

*delim Character to search that will be replaced

with String to replace with

n Maximum number of chars to parse

Returns: The new string

See also: str_replace

char *linux = 'Linux C'; linux = str_nreplace(linux, 'C', 'Cool', strlen(linux)); puts(linux); // -- OR -- char *name = 'rAfAel steil'; name = str_nreplace(name, 'A', 'a', 3); puts(n);

Replace characteres in a string.Replace all occourences of *delim on *src with characteres pointed by *with. The problem with the folowing code is that the function only searches for the first caracter of *delim, ingoring the rest. Other problem is speed relacioned: note that the function ever compare the length of *with to do the correct action.

Parameters: src String to parse

delim Character to search that will be replaced

with String to replace with

Returns: The new string

See also: str_nreplace

char *linux = 'Linux C'; linux = str_replace(linux, 'C', 'Cool'); puts(linux); // -- OR -- char *name = 'rAfAel steil'; name = str_replace(name, 'A', 'a'); puts(n);

Delete characters from a string.Delete count characters of s, starting in start

Parameters: s String to search

*txt = 'Some text to test anything'; puts(txt); txt = strdel(txt, 2, 8); puts(txt);

Strip no more than 'n' slashes from a string.Strip the backslash character ( \ ) from a string, stopping after 'n' char

Parameters: s String to parse

n Maximum number of chars to parse

Returns: The new string, without slashes

See also: addslashes, stripslashes

char *name = 'My another string is called \'blablabla\''; puts(n); // will display My another string is called 'blablabla' name = stripslashes(name, 33); puts(n); // will display My another string is called 'blablabla'
