strtr function numeric character substitution garbled My replacement thesaurus comes from a text file. Text files either changed to GBK or the utf-8 format are garbled. If you define the replacement thesaurus yourself as follows: $words = Array (' say ' = ' dddddddddddddddddddd '); Replace will not garbled $data [' content '] = STRTR ($data [' content '], $words); I print out the words variable, the phrase inside is not garbled, with function detect

around, you can use a simple example to describe, a simple look at a piece of code:Add a P package to all elements$ (' div '). Wrapinner (' The final structure, the inner element of the matching di element is wrapped by P. Wrapinner (function) : allows us to use a callback function to make arguments, each time a matching element is encountered, the function is executed, returning a DOM element, jquery object, or HTML fragment to wrap the contents of the matching elementTake the above case as
