Samb.. ,[object Object],[object Object],[object Object],[object Object]

Access MySQL dr PHP ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],$connection = mysql_connect(“localhost”,”root”,””); $selection = mysql_select_db(“namaDB”);

[object Object],[object Object],[object Object],[object Object],[object Object],$sql=" SELECT * from tableDB"; $result=mysql_query($sql)or die("SQL select statement failed"); $sql = “INSERT INTO tableDB(nama column) VALUES (isi column)”; $result = mysql_query($sql); If($result)…. $sql = " DELETE FROM tableDB "; $result = mysql_query($sql); $sql = “ UPDATE tableDB SET <nama column>=<isi column> WHERE….”; $result = mysql_query($sql);

INSERT INTO ,[object Object],<html> <head> <title>Belajar Php</title> </head> <form method="post" action="add.php"> <body> Tentang Saya Nama: <input type="text" name="Nama" size="40"> Umur : <input type="text" name=“Umur" size="40"> Jawatan : <input type="text" name="Nama" size="40"> <input type="submit" name="Submit" value="Hantar"> <input name="reset" type = "reset" Value = "Batal"> </body></html> add.html Hasilnya

Samb.. ,[object Object],<?php $Nama=$_POST["Nama"]; $Umur=$_POST["Umur"]; $Jawatan=$_POST["Jawatan"]; $connection=mysql_connect("localhost","root","") or die ("Could not connect to MySQL".mysql_error()); $selection=mysql_select_db("php") or die("Unable to select database.".mysql_error()); $sql="INSERT INTO belajar(Nama,Umur,Jawatan) VALUES('$Nama','$Umur','$Jawatan')"; $result=mysql_query($sql); if($result){echo "<b>Maklumat telah di Terima</b>"; echo "<p><b>Nama :$Nama</b>"; echo"<p><b>Umur :$Umur</b>"; echo"<p><b>Jawatan :$Jawatan</b>"; } else {die(mysql_error());} ?> add.php

SELECT ,[object Object],<html><head> <title>belajar Php</title> </head><body> <a href="view.php">Senarai DB</a> </body><html> view.html Hasilnya

Samb.. ,[object Object],<?php $connection=mysql_connect("localhost","root","") or die("could not connect to MySQL".mysql_error()); $selection=mysql_select_db("php") or die("Unable to select database".mysql_error()); $sql="SELECT*from belajar"; $result=mysql_query($sql) or die("SQL select statement failed"); $result=mysql_query($sql); echo"<table align='center' border='1' bgcolor='green'>"; echo "<tr><td>Nama</td><td>Umur</td><td>Jawatan</td></tr>"; while($row=mysql_fetch_array($result)){ $Nama=$row["Nama"]; $Umur=$row["Umur"]; $Jawatan=$row["Jawatan"]; echo "<tr><td>$Nama</td><td>$Umur</td><td>$Jawatan</td></tr>";} echo"</table>"; ?> Hasilnya view.php

UPDATE ,[object Object],<html><head><title>Belajar php</title></head> <form method="post" action=“update.php"> <body> Kemaskini Maklumat Masukkan Nama : <input type="text" name="Nama" size="40"> <input type="submit" name=“submit" value="Hantar"> <input name="reset" type = "reset" Value = "Batal"> </body></html> update.html Hasilnya

Samb.. ,[object Object],<form method="post" action="update.php"> <?php $connection = mysql_connect("localhost","root") or die("Could not connect to MySQL".mysql_error()); $selection = mysql_select_db("php") or die("Unable to select database.".mysql_error()); $submit = $_POST["submit"]; if($submit =="Hantar") { if(isset($_POST["Nama"])) { $Nama = $_POST["Nama"]; $sql = "SELECT * from belajar where Nama = '$Nama'"; $result = mysql_query($sql) or die("SQL select statement failed"); $row = mysql_fetch_array($result); echo "Nama : <b>$row[Nama]</b><p>"; echo "Umur :<b>$row[Umur]</b><p>"; echo "Jawatan :<input type='text' name = 'Jawatan' value = '$row[Jawatan]' size = '40'<p>"; echo "<input type = 'hidden' name = 'Nama' value = $row[Nama]><p>"; echo "<input type = 'submit' name = 'submit' value = 'update'>"; } } if($submit == "update") {$Nama = $_POST["Nama"]; $Umur = $_POST["Umur"]; $Jawatan = $_POST["Jawatan"]; $sql = "UPDATE belajar SET Jawatan = '$Jawatan'WHERE Nama = '$Nama'"; $result = mysql_query($sql); echo "<hr><h2> Maklumat telah Dikemaskini</h2><p>"; echo "Nama : $Nama <p>"; echo "Umur : <u><b>$Umur</b></u>"; echo "Jawatan : <u><b>$Jawatan</b></u><br>"; } ?> Update.php

Samb.. ,[object Object],Perlu menekan butang update. Agar maklumat dapat dikemaskini dalam DB Ini adalah hasil setelah butang update klik.

DELETE ,[object Object],<html><head><title>Belajar php</title></head> <form method="post" action="lupus.php"> <body> PERLUPUSAN MAKLUMAT Masukkan Nama : <input type="text" name="Nama" size="40"> <input type="submit" name=“submit" value="Hantar"> <input name="reset" type = "reset" Value = "Batal"> </body></html> lupus.html hasilnya

Samb… ,[object Object],<?php $connection=mysql_connect("localhost","root","") or die("could not connect to MySQL".mysql_error()); $selection=mysql_select_db("php") or die("Unable to select database".mysql_error()); $submit = $_POST["submit"]; if($submit == "Cari") { if(isset($_POST["Nama"])) {$Nama = $_POST["Nama"]; $sql= "SELECT * FROM belajar where Nama = '$Nama'"; $result = mysql_query($sql) or die ("SQL selsct statement failed"); if($row = mysql_fetch_array($result)) { echo "<b><i>Ini adalah maklumat yang anda ingin lupuskan</i></b><p>"; echo "Nama : <b>$row[Nama]</b><p>"; echo "Umur : <b>$row[Umur]</b><p>"; echo "Jawatan : <b>$row[Jawatan]</b><p>"; echo "<input type = 'hidden' name = 'Nama' value = '$row[Nama]'>"; echo "<input type = 'submit' name = 'submit' value = 'DELETE?'>";} else { echo "No record found";} } } if($submit=="DELETE?") { $Nama = $_POST["Nama"]; $sql = "DELETE FROM belajar WHERE Nama = $Nama"; $result = mysql_query($sql); echo "<hr><h2> Penghapusan Berjaya</h2><br>"; } ?> </form> lupus.php
