A. CONTROL STRUCTURE
1.1. FOR
for ($ i = 1; $ i <= 10; $ i + +) {
echo $ i;
}
1.2. WHILE
$ I = 1;
while ($ i <= 10) {
echo $ i + +;
}
DO ... WHILE
$ I = 0;
do {
echo $ i;
} While ($ i> 0);
1.3. IF
if ($ a> $ b)
echo "a is greater than b";
ELSE
if ($ a> $ b) {
echo "a is greater than b";
Else {}
echo "a is not greater than b";
}
ELSE IF
if ($ a> $ b) {
echo "a is greater than b";
} Elseif ($ a == $ b) {
echo "a equal to b";
Else {}
echo "a is smaller than b";
}
1.4. SWITCH
switch ($ i) {
case 0:
echo "i equals 0";
break;
case 1:
echo "i equals 1";
break;
case 2:
echo "i equals 2";
break;
}
switch ($ i) {
case "apple":
echo "i contents apples";
break;
case "orange":
echo "i it orange";
break;
case "barked":
echo "i it barked";
break;
}
2. USER FUNCTION
function multiply ($ num1, $ num2)
{
return $ num1 * $ num2;
}
echo multiplication (3.4) / / output '12 '.
3. INTERNAL FUNCTIONS
3.1. STRING PARSING
3.1.1. Explode
Syntax: array explode (string $ delimiter, string $ string [, int $ limit])
Example:
$ Yogyakarta = "Yogyakarta, Sleman, Bantul, South Mountain, Kulonprogo";
$ District = explode (",", $ Yogyakarta);
echo $ district [0]; / / Yogyakarta
echo $ district [3]; / / Gunungkidul
Implode
Syntax: string implode (string $ glue, array $ pieces)
Example:
$ Array = array ('module', 'Practice', 'E-Commerce');
$ Join = implode ("-", $ array);
echo $ join; / / module-Lab-E-Commerce
3.1.2. Strlen
Syntax: int strlen (string $ string)
Example:
$ Str = 'E-Commerce';
echo strlen ($ str) / / 10
SUBSTR
Syntax: string substr (string $ string, int $ start [, int $ length])
Example:
$ Rest = substr ("abcdef", -1); / / result: "f"
$ Rest = substr ('abcdef', -2); / / result: "ef"
$ Rest = substr ("abcdef", -3, 1); / / result: "d"
$ Rest = substr ("abcdef", 0, -1); / / result: "abcde"
$ Rest = substr ("abcdef", 2, -1); / / result: "CDE"
$ Rest = substr ("abcdef", 4, -4); / / result: ""
$ Rest = substr ("abcdef", -3, -1); / / result: "de"
3.2. STRING formating
3.2.1. Printf, sprintf
Example 1:
$ Number = 12345;
$ Tulisan1 = 'PHP';
$ Tulisan2 = 'E-Commerce';
$ Format = '% s Learning to learn% s lucky number
% D ';
printf ($ format, $ tulisan1, $ tulisan2, $ number);
Example 2:
<? Php
$ S = 'amikom';
$ T = 'amikom student';
printf ("[% s] \ n", $ s); / / output common
printf ("[% 15s] \ n", $ s); / / 15 characters with spaces flush right
printf ("[%-15s] \ n", $ s); / / 15 characters with spaces left flat
printf ("[% 015s] \ n", $ s); / / 15 characters padding 0
printf ("[% '# 15s] \ n", $ s); / / 15 characters padding #
printf ("[% 15.10s] \ n", $ t) / / 15 characters cut of 10 characters
?>
Results:
[Amikom]
[Amikom]
[Amikom]
[000000000amikom]
[# # # # # # # # # Amikom]
[Student]
Example 3:
$ Uang1 = 68.75;
$ Uang2 = 54.35;
$ Money = $ + $ uang2 uang1;
/ / Echo $ money will output "123.1";
echo $ money;
$ Formatted = sprintf ("Rp.% 01.2f", $ currency);
/ / Echo $ formatted output "Rp.123.10"
echo $ formatted;
3.2.2. Str_replace, STR_IREPLACE
Example 1:
$ BodyTag = str_replace ("% body%", "black", "<body text='%body%'>");
Example 2:
$ Vowels = array ("a", "e", "i", "o", "u", "A", "E", "I", "O", "U");
$ Gantivokal = str_replace ($ vowels, "o", "Learning E-Commerce");
echo $ gantivokal;
Example 3:
$ Phrase = "You must learn to courtship, the streets, watching movies
to college. ";
$ Goodness = array ("PHP", "MySQL", "SEO");
$ Ugliness = array ("going out", "the streets", "movies");
$ Kalimatbaru = str_replace ($ evil, $ good, $ sentence);
echo $ kalimatbaru;
STR_IREPLACE str_replace just NOT the same as CASE SENSITIVE.
3.2.3. Htmlentities
Example:
$ Str = "A sign of 'quotation', written by <b> bold </ b>";
/ / Output: A sign of 'quotation', written by
<b> bold </ b>
echo htmlentities ($ str);
/ / Output: A sign of 'quotation', written by
<b> bold </ b>
echo htmlentities ($ str, ENT_QUOTES);
3.2.4. Html_entity_decode
Example:
$ Orig = "A sign \" quote \ "written by <b> bold </ b>";
$ A = htmlentities ($ orig, ENT_QUOTES);
$ B = html_entity_decode ($ a);
echo $ a; / / A sign of "quotation" written by
<b> bold </ b>
echo $ b; / / A sign of "quotation" written by <b> bold </ b>
3.2.5. Htmlspecialchars
Example:
$ Code = htmlspecialchars ("Fit & Proper <a href='test'>
Test </ a> ", ENT_QUOTES);
echo $ code; / / <a href='test'> Fit & Proper
Test </ a>
3.3. MATHEMATICS (To Be Continued ....)
3.3.1. ABS
3.3.2. Ceil
3.3.3. FLOOR
3.3.4. MAX
3.3.5. MIN
3.3.6. ROUND
3.3.7. RAND
3.3.8. FMOD
3.4. DATE & TIME
3.5. Sending MAIL
function multiply ($ num1, $ num2)
{
return $ num1 * $ num2;
}
echo multiplication (3.4) / / output '12 '.
