Article Introduction：The method of splitting strings by multiple delimiters in PHP is achieved through regular expressions. 1. The basic syntax is preg_split('/pattern/',$subject), for example, it can be written as $parts=preg_split('/[,:;]/',$string); 2. In order to deal with spaces and other whitespace characters, you can add \\s* to the regular, such as $parts=preg_split('/\s[,;:]\s/',$string), which can automatically clear unnecessary spaces; 3. If you want to exclude null values ??caused by continuous separators, you can add PREG_SPLIT_N

Article Introduction：The most common way to split a string in PHP is to use the exploit function. 1. Using the exploit function is simple and efficient, suitable for most scenarios. 2. When dealing with multiple separators, using preg_split and regular expressions is more flexible, but you need to pay attention to performance and correctness. 3. When limiting the number of segmentation times, the third parameter of the exploit function is very useful. 4. Complex formats can be processed in combination with exploit and preg_split. 5. When processing large-scale data, the strtok function can improve efficiency.

Article Introduction：Use exploit() for simple string segmentation, suitable for fixed separators; 2. Use preg_split() for regular segmentation, supporting complex patterns; 3. Use implode() to concatenate array elements into strings; 4. Use strtok() to parse strings successively, but pay attention to their internal state; 5. Use sscanf() to extract formatted data, and preg_match_all() to extract all matching patterns. Select the appropriate function according to the input format and performance requirements. Use exploit() and implode() in simple scenarios, use preg_split() or preg_match_all() in complex modes, and use strto to parse step by step

Article Introduction：To convert a string to a PHP array, you need to select the method according to the format: 1. Use exploit() to separate the comma and use array_map(trim) to remove spaces; 2. Use json_decode($str,true) to parse; 3. Use parse_str() to convert the associative array to the URL parameters; 4. Complex structures combine functions such as preg_split() and exploit() to process key-value pairs. Different formats correspond to different conversion strategies, and the key is to identify the string structure.

Article Introduction：This tutorial explains in detail how to use PHP configuration files and PHPMailer to implement the function of sending emails to multiple recipients. In response to the PHPMailer's addAddress() method does not support directly dealing with comma-separated mailbox strings. The article provides a solution to parse multi-mailbox strings based on the preg_split function, and further introduces how to batch clean, deduplicate and validate the parsed mailbox addresses through custom functions to ensure the stability and accuracy of email sending.
