Test code

Test Results


It is found that only var_dump has output, while dump has no output.
Error analysis, locate htmlspecialchars
Trace the debugging function to check the htmlspecialchars function.

Official Website Description: Prior to version 5.4, the default encoding of this function is ISO-8859-1, 5.4 and 5.5 default encoding is UTF-8, after 5.6 is used as the default encoding configuration. P>
PHP Version 5.6.21, The htmlspecialchars encoding is the encoding of the configuration item, as follows:

Htmlspecialchars uses UTF-8 encoding, for gbk, gb2312 and other Chinese encoded strings, there is no output. No output is provided if the string of the htmlspecialchars function parameter contains a gbk or gb2312 encoded character. The test is as follows:
$ B = 'Chinese abc'; $ a = iconv ("UTF-8", "GB2312", $ B); $ c = $ B. $ a; var_dump (htmlspecialchars ($ a, ENT_QUOTES); // No output var_dump (htmlspecialchars ($ B, ENT_QUOTES); // The output is var_dump (htmlspecialchars ($ c, ENT_QUOTES); // No output
Solution

$ B = 'Chinese abc'; $ a = iconv ("UTF-8", "GB2312", $ B); $ c = $ B. $ a; var_dump (htmlspecialchars ($ a, ENT_QUOTES, 'iso-8859-1 '); // output, gb2312 encoding Chinese garbled var_dump (htmlspecialchars ($ B, ENT_QUOTES, 'iso-8859-1 '); // The output is var_dump (htmlspecialchars ($ c, ENT_QUOTES, 'iso-8859-1'); // The output is displayed, and the gb2312 encoding is garbled.
So add the htmlspecialchars function in the dump function of Thinkphp to the default encoding ISO-8859-1.
The above thinkphp dump function has no output instance code, which is all the content that I have shared with you. I hope to give you a reference and support for the customer's house.
