기본 사항을 간단히 살펴보고 매일 새롭고 재미있는 독서를 즐겨보세요.
어차피 이 책은 많은 호평을 받았는데, 호주 레드북이 집필한 Machinery Industry Press에서 출판한 `PHP 및 MySQL 웹 개발`입니다. 관심이 있으시면 읽어보셔도 좋습니다.
PHP를 사용한 첫 번째 기사
1. 시작하기
두 번의 클릭으로 5분 안에 읽어보세요.

2. 데이터 저장 및 검색(직접 파일 조작
하고 싶은 말은 모두 코드에 있습니다.

3. 배열
그 외엔 다 진부한 내용이니 그냥 확인하고 사용하세요. 숙련도 문제지만 그래도 알아두셔야 합니다. 그러다가 usort(사용자)를 배웠습니다. 사용자 정의 정렬의 아름다움:
<span> 1</span><span>//</span><span>Chapter3.Array</span><span> 2</span><span>namespace Bible\Basic\ArrayUsort; </span><span> 3</span><span>//</span><span>多维数组的排序</span><span> 4</span><span>$array1</span>=<span>array</span>(54654,545,668<span>); </span><span> 5</span><span>$array2</span>=<span>array</span>(5454,88,37,54<span>); </span><span> 6</span><span>$array3</span>=<span>array</span>(123,4444,5453<span>); </span><span> 7</span><span>$arrayAll</span>=<span>array</span>(<span>$array1</span>,<span>$array2</span>,<span>$array3</span><span>); </span><span> 8</span><span>var_dump</span>(<span>$arrayAll</span><span>); </span><span> 9</span><span>10</span><span>function</span> dimensionsCompare(<span>$x</span>,<span>$y</span><span>) </span><span>11</span><span>{ </span><span>12</span><span>if</span> (<span>$x</span>[1]==<span>$y</span>[1<span>]){ </span><span>13</span><span>return</span> 0<span>; </span><span>14</span> }<span>elseif</span> (<span>$x</span>[1]<<span>$y</span>[1<span>]){ </span><span>15</span><span>return</span> -1<span>; </span><span>16</span> }<span>else</span><span>{ </span><span>17</span><span>return</span> 1<span>; </span><span>18</span><span> } </span><span>19</span><span>} </span><span>20</span> @<span>usort</span>(<span>$arrayAll</span>, "dimensionsCompare"<span>); </span><span>21</span><span>var_dump</span>(<span>$arrayAll</span>);
4. 문자열 연산과 정규식
문자열 정렬
<span>1</span><span>$name</span>=<span>trim</span>(<span>$_POST</span>['name'<span>]); </span><span>2</span><span>$email</span>=<span>rtrim</span>(<span>$_POST</span>['email'<span>]); </span><span>3</span><span>$feedback</span>=<span>chop</span>(<span>$_POST</span>['feedback']);
