I have inserted some JSON data into mysql database. And would like to retrieve it to display it. However it must first pass through a script..

My question is how do I convert a php variable to a javascript variable..

 

The contents of the php variable is

$signature= [{"lx":123,"ly":37,"mx":123,"my":36},{"lx":120,"ly":33,"mx":123,"my":37},{"lx":119,"ly":33,"mx":120,"my":33},{"lx":113,"ly":33,"mx":119,"my":33},{"lx":102,"ly":33,"mx":113,"my":33},{"lx":92,"ly":33,"mx":102,"my":33},{"lx":81,"ly":32,"mx":92,"my":33},{"lx":71,"ly":31,"mx":81,"my":32},{"lx":67,"ly":30,"mx":71,"my":31},{"lx":63,"ly":29,"mx":67,"my":30},{"lx":62,"ly":27,"mx":63,"my":29},{"lx":62,"ly":25,"mx":62,"my":27},{"lx":65,"ly":20,"mx":62,"my":25},{"lx":78,"ly":13,"mx":65,"my":20},{"lx":98,"ly":4,"mx":78,"my":13},{"lx":114,"ly":0,"mx":98,"my":4},{"lx":167,"ly":4,"mx":114,"my":0},{"lx":172,"ly":9,"mx":167,"my":4},{"lx":175,"ly":15,"mx":172,"my":9},{"lx":177,"ly":23,"mx":175,"my":15},{"lx":179,"ly":34,"mx":177,"my":23},{"lx":179,"ly":40,"mx":179,"my":34},{"lx":179,"ly":46,"mx":179,"my":40},{"lx":179,"ly":49,"mx":179,"my":46},{"lx":177,"ly":54,"mx":179,"my":49},{"lx":176,"ly":54,"mx":177,"my":54},{"lx":175,"ly":55,"mx":176,"my":54},{"lx":173,"ly":55,"mx":175,"my":55},{"lx":171,"ly":55,"mx":173,"my":55},{"lx":169,"ly":55,"mx":171,"my":55},{"lx":169,"ly":53,"mx":169,"my":55},{"lx":169,"ly":52,"mx":169,"my":53},{"lx":170,"ly":51,"mx":169,"my":52},{"lx":172,"ly":50,"mx":170,"my":51},{"lx":173,"ly":49,"mx":172,"my":50},{"lx":175,"ly":48,"mx":173,"my":49},{"lx":176,"ly":47,"mx":175,"my":48},{"lx":178,"ly":46,"mx":176,"my":47},{"lx":175,"ly":45,"mx":178,"my":46},{"lx":167,"ly":45,"mx":175,"my":45},{"lx":158,"ly":45,"mx":167,"my":45},{"lx":147,"ly":45,"mx":158,"my":45},{"lx":136,"ly":45,"mx":147,"my":45},{"lx":125,"ly":45,"mx":136,"my":45},{"lx":118,"ly":45,"mx":125,"my":45},{"lx":111,"ly":45,"mx":118,"my":45},{"lx":107,"ly":45,"mx":111,"my":45},{"lx":104,"ly":45,"mx":107,"my":45},{"lx":103,"ly":45,"mx":104,"my":45},{"lx":108,"ly":43,"mx":103,"my":45},{"lx":123,"ly":40,"mx":108,"my":43},{"lx":139,"ly":38,"mx":123,"my":40},{"lx":156,"ly":37,"mx":139,"my":38},{"lx":168,"ly":35,"mx":156,"my":37},{"lx":176,"ly":35,"mx":168,"my":35},{"lx":180,"ly":35,"mx":176,"my":35},{"lx":181,"ly":35,"mx":180,"my":35},{"lx":44,"ly":17,"mx":44,"my":16},{"lx":46,"ly":16,"mx":44,"my":17},{"lx":47,"ly":16,"mx":46,"my":16},{"lx":56,"ly":16,"mx":47,"my":16},{"lx":65,"ly":16,"mx":56,"my":16},{"lx":78,"ly":16,"mx":65,"my":16},{"lx":91,"ly":17,"mx":78,"my":16},{"lx":101,"ly":18,"mx":91,"my":17},{"lx":109,"ly":19,"mx":101,"my":18},{"lx":117,"ly":21,"mx":109,"my":19},{"lx":121,"ly":21,"mx":117,"my":21},{"lx":126,"ly":21,"mx":121,"my":21},{"lx":128,"ly":21,"mx":126,"my":21},{"lx":129,"ly":19,"mx":128,"my":21},{"lx":130,"ly":19,"mx":129,"my":19},{"lx":131,"ly":18,"mx":130,"my":19},{"lx":139,"ly":18,"mx":131,"my":18},{"lx":151,"ly":19,"mx":139,"my":18},{"lx":165,"ly":23,"mx":151,"my":19},{"lx":178,"ly":26,"mx":165,"my":23},{"lx":188,"ly":28,"mx":178,"my":26},{"lx":197,"ly":29,"mx":188,"my":28},{"lx":205,"ly":29,"mx":197,"my":29},{"lx":210,"ly":29,"mx":205,"my":29},{"lx":214,"ly":29,"mx":210,"my":29},{"lx":217,"ly":26,"mx":214,"my":29},{"lx":219,"ly":24,"mx":217,"my":26},{"lx":219,"ly":22,"mx":219,"my":24},{"lx":219,"ly":18,"mx":219,"my":22},{"lx":219,"ly":15,"mx":219,"my":18},{"lx":219,"ly":13,"mx":219,"my":15},{"lx":219,"ly":11,"mx":219,"my":13},{"lx":218,"ly":12,"mx":219,"my":11},{"lx":218,"ly":14,"mx":218,"my":12},{"lx":218,"ly":17,"mx":218,"my":14},{"lx":218,"ly":21,"mx":218,"my":17},{"lx":218,"ly":26,"mx":218,"my":21},{"lx":218,"ly":30,"mx":218,"my":26},{"lx":217,"ly":33,"mx":218,"my":30},{"lx":216,"ly":36,"mx":217,"my":33},{"lx":216,"ly":37,"mx":216,"my":36},{"lx":215,"ly":37,"mx":216,"my":37},{"lx":215,"ly":36,"mx":215,"my":37},{"lx":213,"ly":33,"mx":215,"my":36},{"lx":212,"ly":30,"mx":213,"my":33},{"lx":208,"ly":28,"mx":212,"my":30},{"lx":200,"ly":27,"mx":208,"my":28},{"lx":192,"ly":27,"mx":200,"my":27},{"lx":184,"ly":27,"mx":192,"my":27},{"lx":174,"ly":29,"mx":184,"my":27},{"lx":164,"ly":32,"mx":174,"my":29},{"lx":152,"ly":35,"mx":164,"my":32},{"lx":142,"ly":38,"mx":152,"my":35},{"lx":134,"ly":41,"mx":142,"my":38},{"lx":129,"ly":42,"mx":134,"my":41},{"lx":124,"ly":43,"mx":129,"my":42},{"lx":120,"ly":44,"mx":124,"my":43},{"lx":118,"ly":44,"mx":120,"my":44},{"lx":116,"ly":44,"mx":118,"my":44},{"lx":116,"ly":45,"mx":116,"my":44},{"lx":116,"ly":50,"mx":116,"my":45},{"lx":116,"ly":56,"mx":116,"my":50},{"lx":116,"ly":60,"mx":116,"my":56},{"lx":114,"ly":63,"mx":116,"my":60},{"lx":111,"ly":65,"mx":114,"my":63},{"lx":106,"ly":66,"mx":111,"my":65},{"lx":103,"ly":66,"mx":106,"my":66},{"lx":98,"ly":66,"mx":103,"my":66},{"lx":95,"ly":66,"mx":98,"my":66},{"lx":91,"ly":64,"mx":95,"my":66},{"lx":86,"ly":62,"mx":91,"my":64},{"lx":83,"ly":60,"mx":86,"my":62},{"lx":80,"ly":58,"mx":83,"my":60},{"lx":78,"ly":56,"mx":80,"my":58},{"lx":76,"ly":55,"mx":78,"my":56},{"lx":75,"ly":53,"mx":76,"my":55},{"lx":75,"ly":51,"mx":75,"my":53},{"lx":75,"ly":50,"mx":75,"my":51},{"lx":75,"ly":49,"mx":75,"my":50},{"lx":75,"ly":47,"mx":75,"my":49},{"lx":77,"ly":47,"mx":75,"my":47},{"lx":79,"ly":47,"mx":77,"my":47},{"lx":81,"ly":47,"mx":79,"my":47},{"lx":82,"ly":47,"mx":81,"my":47}

The way I understand that OP, $signature is actually the js var (it's part of the js he wants to output). So basically just echo out the php variable you store that whole thing in (make sure it's within script tags of course).

 

Example (truncated for brevity):

 

<?php

$variableFromDatabase = '$signature= [{"lx":123,"ly":37,"mx":123,"my":36}]';
echo "<script type='text/javascript'>$variableFromDatabase</script>";

?>
