We can get the first element of the given array by accessing the 0 index because the indexing of the array elements starts with 0 (zero) instead of 1. So, by accessing the 0 index of the given array, we can get the first array element....

这里可以看出,忽略前置空格是最先做的动作;当遇到第一个[时,php则认为数数组,不再进行转换,设置了is_array = 1就 break 了。 这个is_array有什么用呢,往下看: 代码语言:javascript 复制 if(is_array){int nest_level=0;while(1){char*index_s;size_t new_idx_len=0;ip++;// [ 的下一个字符index...
