8. php数组 第4章 数据处理-php数组的处理-郑阿奇
Introduction: PHP Array: PHP Array Chapter 4 Data Processing - PHP Array Processing - Zheng Aqi: 1. Array Processing: 1.1 Array Creation and Initialization: 1. The array() function creates an array, by default The next 0 elements are the first elements of the array. The count() and sizeof() functions obtain the number of data elements. 2. Create an array using variables. compact() finds the variable name in the current symbol table and adds it to the output. In the array, the variable name becomes the key name and the content of the variable becomes the value of the key. Copy the code as follows:
